INTRODUCTION
The ODYSSEY
®
battery ingeniously uses Absorbed Glass Mat (AGM) Valve Regulated Lead Acid (VRLA) technology to offer,
in one package, the characteristics of two separate batteries. It can deep cycle as well as deliver serious cranking power.
Traditional battery designs allow them to either deep cycle or provide high amperage discharges for applications such as engine
starting. The ODYSSEY battery can support applications in either category. ODYSSEY batteries are capable of providing engine
cranking pulses of up to 2,250A (PC2250) for 5 seconds at 77ºF (25ºC) as well as deliver 400 charge/discharge cycles to 80%
Depth of Discharge (DOD) when properly charged. A typical Starting, Lighting and Ignition (SLI) battery, for example, is designed to
provide short-duration, high-amperage pulses; it performs poorly when repeatedly taken down to deep DOD or if they are placed
on a continuous trickle charge, such as when they are used to crank a backup generator. A traditional battery resembles either a
sprinter or a long distance runner; an ODYSSEY battery will do both – provide short duration high amperage pulses or low rate,
long duration drains.
WHY USE ODYSSEY®BATTERIES?
Guaranteed longer service life
With an 8- to 12-year design life in float (emergency power) applications at 77ºF (25ºC) and a 3- to 10-year service life depending
on the nature of the non-float applications, ODYSSEY batteries save you time and money because you do not have to replace
them as often. Unlike other AGM VRLA batteries, the ODYSSEY battery is capable of delivering up to 400 cycles when
discharged to 80% DOD and properly charged.
Longer storage life
Unlike conventional batteries that need a recharge every six to 12 weeks, a fully charged ODYSSEY battery can be stored
for up to two years at 77ºF (25ºC) from a full state of charge. At lower temperatures, storage times will be even longer.
Deep discharge recovery
The ease with which an ODYSSEY battery can recover from a deep discharge is extraordinary. A later section on storage and
recharge criteria discusses test data on this important topic.
Superior cranking and fast charge capability
The cranking power of ODYSSEY batteries is superior to that of equally sized conventional batteries, even when the temperature is
as low as -40°F (-40ºC). In addition, with simple constant voltage charging there is no need to limit the inrush current, allowing the
battery to be rapidly charged. Please see the section titled Rapid charging of ODYSSEY batteries for more details on this feature.
Easy shipping
Because of the starved electrolyte design, the ODYSSEY battery has been proven to meet the US Department of Transportation
(USDOT) criteria for a non-spillable battery. They can be shipped by highway, air or sea as specified on our SDS that can be found
at www.odysseybattery.com.
Tough construction
The rugged construction of the ODYSSEY battery makes it suitable for use in a variety of environments ranging from marine to
over-the-road trucks and powersports applications.
Mounting flexibility
Installing the ODYSSEY battery in any orientation other than inverted does not affect any performance attribute. There is also no
fear of acid spillage.
Superior vibration resistance
ODYSSEY batteries have passed a variety of rigorous tests that demonstrate their ruggedness and exceptional tolerance of
mechanical abuse. Please see the section titled Shock, Impact and Vibration testing for more details on these tests.
Ready out of the box
ODYSSEY batteries ship from the factory fully charged. If the battery’s open circuit voltage is higher than 12.65V, simply install it
in your vehicle and you are ready to go; if below 12.65V boost charge the battery following the instructions in this manual or the
owner’s manual. For optimum reliability, a boost charge prior to installation is recommended, regardless of the battery’s Open
Circuit Voltage (OCV).

EXTENDED DISCHARGE CHARACTERISTICS
In addition to its excellent pulse discharge capabilities, the ODYSSEY®battery can deliver many deep discharge cycles,
yet another area where the ODYSSEY battery outperforms a conventional SLI battery, which can deliver only a few deep
discharge cycles.
The following twenty graphs show detailed discharge characteristics of the entire ODYSSEY battery line. The end of discharge
voltage in each case is 10.02V per battery or 1.67 volts per cell (VPC). Each graph shows both constant current (CC) and
constant power (CP) discharge curves at 77ºF (25ºC). The table next to each graph shows the corresponding energy and
power densities. The battery run times extend from 2 minutes to 20 hours.

CYCLE LIFE AND DEPTH OF
DISCHARGE (DOD)
Applications in which the battery is frequently discharged
and recharged are called cyclic. A complete cycle starts with
a charged battery that is discharged and then brought back
to a full state of charge. Battery life in these applications is
stated as the number of cycles the battery will deliver before
its capacity drops to 80% of its rated value. For example,
suppose a battery is rated at 100 amp-hours (Ah) and has a
published cycle life of 400. This means that the battery can
be cycled 400 times before its delivered capacity drops to
80Ah.
Proper charging and DOD are the two key factors that
determine how many cycles a battery will deliver before it
reaches end of life. The DOD is simply the ratio of capacity
extracted from the battery to its rated capacity expressed as
a percentage. If a 100Ah battery delivers 65Ah and is then
recharged, it is said to have delivered a 65% DOD cycle.
The relationship between DOD and cycle life for ODYSSEY®
batteries, excluding PC370, PC950 and PC1100, is shown
in Figure 1. The lower the DOD the higher the number of
cycles the battery will deliver before reaching end of life.
Figure 1
FLOAT LIFE
Float life refers to the life expectancy of a battery that is
used primarily as a source of backup or emergency power.
Emergency lighting, security alarm and Uninterruptible
Power Systems (UPS) are good examples of batteries in
float applications. In each of these applications the battery is
discharged only if the main utility power is lost; otherwise the
battery remains on continuous trickle charge (also called float
charge).
Since ODYSSEY®batteries are dual purpose by design, they
offer a long-life battery option in float applications. At room
temperature (77°F or 25°C) these batteries have a design life
of 10+ years in float applications; at end of life an ODYSSEY
battery will still deliver 80% of its rated capacity.
ODYSSEY®BATTERY STORAGE AND
DEEP DISCHARGE RECOVERY
For any rechargeable battery, storage and recharge are
important criteria. This section provides some guidelines
that will help you get the most from your ODYSSEY battery.

battery?

Use Figure 2 to determine the SOC of the ODYSSEY
battery, as long as the battery has not been charged or
discharged for six or more hours. The only tool needed is
a good quality digital voltmeter to measure its OCV1. The
graph shows that a healthy, fully charged ODYSSEY battery
will have an OCV of 12.84V or higher at 77ºF (25ºC).

1The OCV of a battery is the voltage measured between its positive and negative terminals without the battery connected to an external
circuit (load). It is very important to take OCV reading only when the battery has been off charge for at least 6-8 hours, preferably overnight.

(B) How long can the battery be stored?
ODYSSEY®batteries should be fully charged prior to
storage. Fully charged ODYSSEY batteries can be stored
for up to 24 months at 77ºF (25ºC). Battery voltage naturally
decreases with time and with increased temperature.
The battery voltage should be checked periodically. If the
battery voltage drops to 12.0 volts (35% state of charge)
it should be recharged immediately to avoid permanent
battery damage. The following can be used as a rough
approximation for the potential storage times at different
temperatures.
Figure 3: ODYSSEY®battery storage time at
temperatures

(2) High temperature discharged storage test
Two PC1200 samples were discharged in this test at the
1-hour rate to 9V per module, and then placed in storage at
122°F (50°C) in a discharged condition for 4 weeks.
At the end of 4 weeks, the two batteries were recharged
using a constant voltage (CV) charge at 14.7V per battery.
As Figure 4 below shows, both samples recovered from this
extreme case of abusive storage.

(C) Can the battery recover from deep discharge
conditions?
Yes, the ODYSSEY battery can recover from extremely deep
discharges as the following test results demonstrate.
(1) German DIN standard test for overdischarge recovery
In this test, a PC925 was discharged over 20 hours (0.05C10
rate)2to 10.20V. After the discharge2a 5Ωresistor was
placed across the battery terminals and the battery kept in
storage for 28 days.
At the end of the storage period, the battery was charged
at 13.5V for only 48 hours. A second 0.05C10 discharge
yielded 97% of rated capacity, indicating that a low rate
48-hour charge after such a deep discharge was insufficient;
however, the intent of the test is to determine if the battery

Extreme cold temperature performance
High discharge rate performance in extremely cold
conditions is another area in which ODYSSEY® batteries
excel. An example of this is shown in Figure 5. Even at
-40°F (-40°C) the battery was able to support a 550A
load for over 30 seconds before its terminal voltage
dropped to 7.2V.

a standby float charger. A standard automotive charger at
14.4V would have allowed the battery to recover greater
10.0
than 97% of its capacity. 9.0
These test results prove that ODYSSEY batteries can 8.0
recover from deep discharge conditions. Reinforcing this 7.0
conclusion is the next test, which is even harsher than the 6.0
DIN standard test, because in this test the battery was
stored in a discharged state at a temperature of 122°F Run time in seconds
(50°C).
Since all ODYSSEY batteries are designed similarly, one can
expect similar outstanding cold temperature performance
from any of the other ODYSSEY batteries.
2The C10 rate of charge or discharge current in amperes is numerically equal to the 10 hour rated capacity of a battery in ampere-hours
divided by 10. Thus, a 26Ah battery at the 10-hour rate, such as the PC925, would have a C10 rate of 2.6A.

PARASITIC LOADS
With the proliferation of more and more electronic
equipment in cars, trucks, motorcycles and powersports
equipment, the phenomenon of parasitic loads is becoming
a serious problem.
Parasitic loads are small currents, typically of the order
of a few milliamps (mA) that the battery has to deliver
continuously. Retaining memories and operating security
systems are common examples of parasitic drains on
batteries in modern systems.
On the surface it would seem that such small loads would
not be a factor in the overall scheme of things. However,
since parasitic loads can be applied on a long-term basis
(weeks or months is not uncommon), the cumulative amp-
hours (Ah) extracted from the battery can be significant.
For example, a 10mA draw on a motorcycle battery will
discharge it by 0.24Ah per day. If left unchecked for 30
days, that small 10mA parasitic load will discharge a 20Ah
battery by 7.2Ah – a 36% depth of discharge (DOD).
Regardless of the application, it is important to make sure
your battery does not have a parasitic load; if there is a slow
drain, connect the battery to a float (trickle) charger that
puts out between 13.5V and 13.8V at the battery terminals.
Physically disconnecting one of the battery cables is an
alternate method to eliminate the drain.

CHARGING ODYSSEY®BATTERIES
Charging is a key factor in the proper use of a rechargeable
battery. Inadequate or improper charging is a common
cause of premature failure of rechargeable lead acid
batteries. To properly charge your premium ODYSSEY®
battery, EnerSys®has developed a special charge algorithm.
It is designed to rapidly and safely charge these batteries.
Called the IUU profile (a constant current mode followed by
two stages of constant voltage charge), Figure 6 shows it in
a graphical format. No manual intervention is necessary with
chargers having this profile.

test was conducted for a total of 100 hours. The battery is
considered to have passed the test if (a) it does not lose any
electrolyte, (b) it is able to support a load test and (c) it does
not leak when subjected to a pressure test.
The ODYSSEY®battery successfully completed this arduous
test.
(B) Shock and vibration test per IEC 61373, Sections 8-10
An independent test laboratory tested an ODYSSEY®
31-PC2150 battery for compliance to IEC standard 61373,
Category 1, Class B, and Sections 8 through 10. Section
8 calls for a functional random vibration test, Section 9
requires a long-life random vibration test and Section 10 is
for a shock test. Table 2, in the next column summarizes the
test results.
If the charger has a timer, then it can switch from absorption
mode to float mode when the current drops to 0.001C10
amps. If the current fails to drop to 0.001C10 amps, then the
timer will force the transition to a float charge after no more
than 8 hours. As an example, for a PC1200 battery, the
threshold current should be 4mA. Another option is to let
the battery stay in the absorption phase (14.7V or 2.45 VPC)
for a fixed time, such as six to eight hours, then switch to
the continuous float charge.

Table 3 shows the minimum charge currents for the full
range of ODYSSEY®batteries when they are used in deep
cycling application. When using a charger with the IUU
profile, we suggest the following ratings for your ODYSSEY
battery. Note the charger current in the bulk charge mode
must be 0.4C10 or more. A list of chargers approved by
EnerSys for use with ODYSSEY batteries is available at
www.odysseybattery.com under FAQs.

Small, portable automotive and powersport chargers may
also be used to charge your ODYSSEY battery. These
chargers are generally designed to bring a discharged
battery to a SOC that is high enough to crank an engine.
Once the engine is successfully cranked, its alternator
should fully charge the battery. It is important to keep in
mind the design limitations of these small chargers when
using them.
Another class of chargers is designed specifically to
maintain a battery in a high SOC. These chargers, normally
in the 3/4amp to 11/2amp range, are not big enough to
charge a deeply discharged ODYSSEY®battery. They must
only be used either to continuously compensate for parasitic
losses or to maintain a trickle charge on a stored battery, as
long as the correct voltages are applied. It is very important,
therefore, to ensure that the ODYSSEY battery is fully
charged before this type of charger is connected to it.
Effect of undercharge in cycling applications
Proper and adequate charging is necessary to ensure that
ODYSSEY batteries deliver their full design life. Generally
speaking, a full recharge requires about 5% more amp-
hours (Ah) must be put back in than was taken out. In other
words, for each amp-hour extracted from the battery, about
1.05Ah must be put back to complete the recharge.
Cycling tests conducted on an ODYSSEY PC545 battery
demonstrated the impact raising the charge voltage from
14.2V to 14.7V has on the cycle life of the battery. The
results are shown in the graph at right.

Samples 1 and 2 were charged at 14.2V while Samples 3
and 4 were charged at 14.7V. All batteries were discharged
at 2.3A until the terminal voltage dropped to 10.02V and
charged for 16 hours. In this particular test, a capacity of
11.5Ah corresponds to 100% capacity and 9.2Ah is 80%
of rated capacity and the battery is considered to have
reached end of life at that point.
The message to be taken from this graph is clear – in deep
cycling applications it is important to have the charge
voltage set at 14.4 – 15.0V. A nominal setting of 14.7V
is a good choice, as shown by the test results.
(A) Selecting the right charger for your battery
Qualifying portable automotive and powersport chargers
for your ODYSSEY battery is a simple two-step process.
Step 1 Charger output voltage
Determining the charger output voltage is the most important
step in the charger qualification process. If the voltage output
from the charger is less than 14.2V or more than 15V for a 12V
battery, then do not use the charger. For 24V battery systems,
the charger output voltage should be between 28.4V and 30V.
If the charger output voltage falls within these voltage limits
when the battery approaches a fully charged state, proceed to
Step 2, otherwise pick another charger.
Step 2 Charger type - automatic or manual
The two broad types of small, portable chargers available
today are classified as either automatic or manual. Automatic
chargers can be further classified as those that charge the
battery up to a certain voltage and then shut off and those
that charge the battery up to a certain voltage and then switch
to a lower float (trickle) voltage.
An example of the first type of automatic charger is one that
charges a battery up to 14.7V, then immediately shuts off.
An example of the second type of automatic charger would
bring the battery up to 14.7V, then switches to a float (trickle)
voltage of 13.6V; it will stay at that level indefinitely. The
second type of automatic charger is preferred, because the
first type of charger will undercharge the battery.
A manual charger typically puts out either a single voltage or
single current level continuously and must be switched off
manually to prevent battery overcharge. Should you choose
to use a manual charger with your ODYSSEY battery, do not
exceed charge times suggested in Table 5 on the next page. It
is extremely important to ensure the charge voltage does not
exceed 15V.

(B) Selecting battery type on your charger
Although it is not possible to cover every type of battery
charger available today, this section gives the ODYSSEY
®
battery user some general charger usage guidelines to follow,
after the charger has been qualified for use with this battery.
In general, do not use either the gel cell or maintenance free
setting, if provided on your charger. Choose the deep cycle
or AGM option, should there be one on your charger. Table
5 below gives suggested charge times based on charger
currents. As previously indicated, deep cycling applications
require a minimum 0.4C10 current available from the charger
so the values shown in Table 5 do not apply to all products in
all applications. To achieve maximum life from your ODYSSEY
battery after completing the charge time in Table 5, we
recommend that you switch your charger to the trickle charge
position and leave the battery connected to the charger for
an additional 6-8 hours. The trickle charge voltage should be
13.5V to 13.8V.

applications

Temperature compensation
Proper charging of all Valve Regulated Lead Acid (VRLA)
batteries requires temperature compensation of the charge
voltage – the higher the ambient temperature the lower the
charge voltage. This is particularly true in float applications
in which the batteries can stay on trickle charge for weeks
or months at a time.

The charge times recommended in Table 5 assume that
the ODYSSEY battery is fully discharged and these charge
times will only achieve about a 80% state of charge. For
partially discharged batteries, the charge times should be
appropriately reduced. The graph in Figure 2, showing
OCV and SOC, must be used to determine the battery’s
SOC. The battery should be trickle charged after high rate
charging, regardless of its initial SOC.
*PC1220 no longer distributed in the United States.
The temperature compensation graphs for ODYSSEY
batteries in float and cyclic applications are shown for
ambient (battery) temperatures ranging from -40°F (-40°C) to
176°F (80°C). The compensation coefficient is approximately
+/-13.3mV per 12V battery per oF (+/-24mV per 12V battery
per °C) variation from 77°F (25°C). Since the charge voltage
and ambient (battery) temperature are inversely related,
the voltage must be reduced as the temperature rises;
conversely, the charge voltage must be increased when the
temperature drops.
Note, however, that the charge voltage should not be
dropped below 13.2V as that will cause the battery grids
to corrode faster, thereby shortening the battery life.
RAPID CHARGING OF ODYSSEY®
BATTERIES
All ODYSSEY batteries can be quickly charged. Figure 7
on the next page shows their exceptional fast charge
characteristics at a constant 14.7V for three levels of inrush
current. These current levels are similar to the output
currents of modern automotive alternators. Table 6 and
Figure 7 show the capacity returned as a function of the
magnitude of the inrush3current.
Standard internal combustion engine alternators with an
output voltage of 14.2V can also charge these batteries.
The inrush current does not need to be limited under
constant voltage charge. However, because the typical
alternator voltage is only 14.2V instead of 14.7V, the
charge times will be longer than those shown in Table 5.
3Inrush is defined in terms of the rated capacity (C10) of the battery. A 0.8C10 inrush on a 100Ah battery is 80A.

Table 6 shows that with a 0.8C10 inrush current, a 100%
discharged battery can have 80% of its capacity returned
in 57 minutes; doubling the inrush to 1.6C10 cuts the time
taken to reach 80% capacity to only 28 minutes.

LOAD TEST PROCEDURE
This procedure should help determine whether the battery
returned by the customer has reached its end of life or simply
needs a full recharge. Depending on the time available one
may choose to perform either the longer load test (Step 4) or
the shorter ½CCA load test (Step 5).
The ½CCA test is quicker but less reliable than the longer test.
This is also the test that is performed when a battery is taken
to an auto store for testing.
1. Measure the OCV of the battery. Proceed to Step 4 or Step
5 if the OCV is equal to or more than 12.80V; if not go to
Step 2.
2. Charge the battery until the device indicates the charge is
complete.
3. Unplug the charger and disconnect the battery from the
charger. Let the battery rest of at least 10-12 hours and
measure the OCV. If it is equal to or more than 12.80V
proceed to the next step; otherwise reject the battery.
4. Long Test: Discharge the battery using a resistor or other
suitable load until the voltage drops to 10.00V and record
the time taken to reach this voltage. Let the battery rest
for an hour and repeat Steps 1 through 4. If the time taken
by the battery to drop to 10.00V is longer in the second
discharge than in the first discharge, the battery may be
returned to service after a full recharge; if not the battery
should be rejected as having reached end of life.
5. ½CCA Test: Battery OCV must be at least 12.60V to
proceed with this test. Connect the load tester cables
and the voltage leads of a separate digital voltmeter
(if the tester does not have a built-in digital voltmeter)
to the battery terminals.
6. Adjust the tester load current to load the battery to
half its rated CCA and apply the load for 15 seconds.
Table 7 shows the ½CCA values for all ODYSSEY®
battery models. Use Table 8 to adjust the battery end
of test voltage temperature.

ODYSSEY®BATTERIES IN NO-IDLE
APPLICATIONS
Since these batteries are dual purpose in nature they can
be used for both engine starting and deep cycling
applications. This makes them particularly well suited for
fleets such as police vehicles that would like to power
their computers and communications equipment without
having to idle their engines. Auxiliary Power Units (APU) on
trucks provide another example of a no-idling application.
All of these require energy sources to power loads such
as computers and refrigerators with the engines shut off to
reduce their carbon footprints and lower gas consumption.
As discussed in a previous section, properly charged
ODYSSEY®batteries are capable of delivering as many
as 400 cycles to a 80% DOD. A shallower discharge will
yield higher cycles, as noted in the cycle life vs. DOD graph
shown earlier. This is the reason why ODYSSEY batteries
are becoming increasingly popular in APU and police fleet
applications that require batteries to have both high cycling
and excellent engine cranking capabilities in the same
package.
Correct Wiring Connections
Positive tap to load
Negative tap to load
Improper Wiring Connections
Positive tap to load
Negative tap to load
PARALLEL CONNECTIONS
It is common to have batteries connected in parallel to
achieve a desired amp-hour capacity. This is done by
connecting all the positives to each other and all the
negatives to each other.
Typically the positive and negative leads to the load
are taken from the same battery; usually the leads from
the first battery are used. This is not a good practice.
Instead, a better technique to connect the load is to take
the positive lead from one end of the pack (the first or last
battery) and the negative lead from the other end of the pack.
The two methods are illustrated above. Solid lines and
arrows indicate positive terminals and leads; broken lines
and arrows indicate negative terminals and leads.
In both illustrations, the positive leads are connected to
each other; similarly the negative leads are connected to
each other. The only difference is that in the first illustration
the positive and negative leads to the load come from the
first and last batteries. In the second case, both leads to
the load are tapped from the same battery.
The first schematic is recommended whenever batteries
are hooked up in parallel to increase battery capacity.
With this wiring, all batteries are forced to share both charge
and discharge currents. In contrast, a closer inspection
of the second schematic shows that it is possible for only
the battery whose terminals are tapped to support the load.
Implementing the first schematic eliminates this possibility
and is therefore a better one.
VENTILATION
VRLA batteries like the ODYSSEY battery depend on the
internal recombination of the gases for proper operation.
This is also why these batteries do not require periodic
addition of water.
The high recombination efficiency of ODYSSEY batteries
make them safe for installation in human environments. It
is not uncommon to see these batteries in aircraft, hospital
operating rooms and computer rooms. The only requirement
is that these batteries must not be installed in a sealed or
gastight enclosure; however, local regulations with respect
to ventilation requirements must be followed.
CONCLUDING REMARKS
We believe that there is no other sealed-lead acid battery
currently available commercially that can match the
ODYSSEY battery for sheer performance and reliability.
We hope that the preceding material will help the reader
arrive at the same conclusion.

FREQUENTLY ASKED SLI BATTERY QUESTIONS
What is the CCA rating?
The Cold Cranking Ampere (CCA) rating refers to the
number of amperes a battery can deliver for 30 seconds
at a temperature of 0°F (-18°C) before the voltage drops
to 1.20 volts per cell, or 7.20 volts for a 12V battery. A 12V
battery that has a rating of 550 CCA means that the battery
will provide 550 amps for 30 seconds at 0°F (-18°C) before
the voltage falls to 7.20V.
What is the MCA rating?
The marine cranking ampere (MCA) rating refers to the
number of amperes a battery can deliver for 30 seconds at
a temperature of 32°F (0°C) until the battery voltage drops
to 7.20 volts for a 12V battery. A 12V battery that has a
MCA rating of 725 MCA means that the battery will give 725
amperes for 30 seconds at 32°F (0°C) before the voltage falls
to 7.20V.
The MCA is sometimes called the cranking amperes or CA.
What is a HCA rating?
The abbreviation HCA stands for hot cranking amps. It is the
same as MCA, CA or CCA, except that the temperature at
which the test is conducted is 80°F (26.7°C).
What is the PHCA rating?
Unlike CCA and MCA the Pulse Hot Cranking Amp (PHCA)
rating does not have an “official” definition; however, we
believe that for true SLI purposes, a 30-second discharge is
unrealistic. The PHCA, a short duration (about three to five
seconds) high rate discharge, is more realistic. Because the
discharge is for such a short time, it is more like a pulse.
Are these gel cells?
No, the ODYSSEY®battery is NOT a gel cell. It is an absorbed
electrolyte type battery, meaning there is no free acid inside
the battery; all the acid is kept absorbed in the glass mat
separators. These separators serve to keep the positive and
negative plates apart.
What is the difference between gel cell and
AGM?
The key difference between the gel cell and the AGM is that
in the AGM cell all the electrolyte is in the separator, whereas
in the gel cell the acid is in the cells in a gel form. If the
ODYSSEY battery were to split open, there would be no acid
spillage! That is why we call the ODYSSEY battery a Drycell
battery.
What is the Ah rating?
The Ah rating defines the capacity of a battery. A battery
rated at 100Ah at the 10-hour rate of discharge will deliver
10A for 10 hours before the terminal voltage drops to a
standard value such as 10.02 volts for a 12V battery. The
PC1200 battery, rated at 40Ah will deliver 4A for 10 hours.
What is reserve capacity rating?
The reserve capacity of a battery is the number of minutes
it can support a 25-ampere load at 80°F (27°C) before its
voltage drops to 10.50 volts for a 12V battery. A 12V battery
with a reserve capacity rating of 100 will deliver 25 amps for
100 minutes at 80°F before its voltage drops to 10.5V.
