INTRODUCTION
The ODYSSEY®battery ingeniously uses Absorbed Glass Mat (AGM) technology to offer,
in one box, the characteristics of two separate batteries. It can deep cycle as well as
provide enormous cranking power – it is almost as if a champion long distance runner
and a world class sprinter are one and the same person.
These batteries are capable of providing engine cranking pulses in excess of 2250A
for five seconds as well as 400 charge/discharge cycles to 80% Depth of Discharge (DOD).
A typical Starting, Lighting and Ignition (SLI) battery can do one or the other, but not both.
It is either a sprinter or a long distance runner; ODYSSEY batteries will do both – provide
short duration high amperage pulse or low rate long duration drains.
In order to achieve the full design cycle life of ODYSSEY batteries in cyclic applications
the charge current must be a minimum of 40% of the battery’s 10-hour rating (column
8 of the chart on page 7). Thus the minimum charge current for a PC925 battery in
a cycling application is 10.8 amps (40% of 27Ah). Please refer to Figure 6 of the
ODYSSEY battery Technical Manual for a detailed discussion of the recommended charge
profile for ODYSSEY batteries in cycling applications, and refer to Table 5 for suggested
charge times. The manual may be downloaded from www.odysseybattery.com.

WHY USE ODYSSEY® BATTERIES?
GUARANTEED LONGER SERVICE LIFE
With an eight to 12 year design life (float) and a three to 10 year service life, ODYSSEY
batteries save you time and money because you do not have to replace the battery as
often. Since actual warranty can vary with your geographical location, please check with
your ODYSSEY battery representative for the warranty specific to your application.
SUPERIOR CRANKING AND FAST CHARGE CAPABILITY
The five second cranking power of ODYSSEY batteries is double to triple that of equally
sized conventional batteries, even when the temperature is as low as -40°F (-40°C). Also,
with simple constant voltage charging (alternator or independent charger), there is no
limitation on the inrush current, so the user is assured of fast charge recovery.
MOUNTING FLEXIBILITY
The ODYSSEY battery may be installed in any orientation (except inverted) without
sacrificing any performance attributes. Acid spillage is avoided due to the fact that the
electrolyte is fully absorbed in the AGM material, and is not free to spill as it is in traditional
flooded batteries. The valve regulated design of the ODYSSEY battery eliminates the need
for an acid vent tube; eliminating the fear of acid burns or damage to expensive chrome
or paint.
2
SUPERIOR VIBRATION RESISTANCE
ODYSSEY®batteries have endured rigorous tests that demonstrate their overall
ruggedness and exceptional tolerance of mechanical abuse.
READY OUT OF THE BOX
ODYSSEY batteries are shipped fully charged. If the ODYSSEY battery's voltage is 12.65V
or greater, simply install the battery in your vehicle and you are ready to go! If below
12.65V, boost charge following the instructions in the ODYSSEY battery Owner’s Manual
and/or Technical Manual. Putting a boost on the battery will not damage it, even if its
voltage reads higher than 12.65V.
WORRY-FREE SHIPPING
Owing to the drycell design, the US Department of Transportation (USDOT) has
classified the ODYSSEY battery as a nonspillable, so it may be shipped worry-free
by express service or by air. Please see our SDS for complete details at
www.odysseybattery.com.
LONGER STORAGE LIFE
Unlike conventional batteries that require a recharge every six to 12 weeks, the ODYSSEY
battery can be stored for up to two years at 77ºF (25ºC) from a fully charged state. These
batteries can be stored for two years or until the open circuit voltage (OCV) drops to
12.00V, whichever comes first.
DEEP DISCHARGE RECOVERY
Should the ODYSSEY battery become deeply discharged, simply recharge following
instructions in this manual.
INSTALLATION
Your ODYSSEY battery is normally ready to install right out of the box! Measure
the battery voltage; if it is 12.65V or greater, install; if less, then refer to the
charging section.

INSTALLATION
1. Using proper procedures as recommended by the vehicle manufacturer, carefully
disconnect the cables from your old battery and remove it from the vehicle. Return
the spent battery to the battery dealer for proper recycling.
2. Inspect existing battery cables for corrosion, acid damage or insulation deterioration.
Replace if deterioration is present.
3. Position your ODYSSEY®battery in the battery holder and fasten firmly to the vehicle.
• Optional height adapter may be used on the Group 34 models for installations where a
group 24 or group 27 is required. Snap the adapter securely into place on the bottom
of the battery. The Group 34 models with this adapter may be used to replace a group
24F or 27F.
4. Connect the positive cable from your ignition to the
Positive (+) terminal.
5. Connect the negative cable from your engine or chassis
to the Negative (-) terminal.
6. Torque the bolt, screw or nut per the specification noted
in table. If you’re using the Accessory Bolt (C), hold the
Brass Post (A) with vise grips and counter torque.
Do the same with General Motors®automotive battery
cable installation.
NOTE: This is a valve regulated sealed battery and never needs
to have water or electrolyte (acid) added. Warranty will be void if opened!
SPECIAL NOTICE!
• CUSTOM V-TWIN MOTORCYCLE INSTALLATIONS USING ODYSSEY PC535, PC545,
PC545MJ, PC680MJ AND PC925LMJ BATTERIES
If your V-Twin motorcycle is equipped with a standard 32 amp single phase stator/
alternator and you ride at a low engine rpm around town or even on long rides, the
appropriate ODYSSEY battery may run out of charge due to low amperage output of the
bike's stator at low rpms. After riding, turn the bike's engine off but leave the lights on for
30 seconds. Then, turn everything off and connect the ODYSSEY battery charger using
the proper procedure as detailed in the ODYSSEY battery charger owner's manual.
• Prolonged storage of vehicles with fuel injection computers, alarms, GPS and other
electrical devices that require continuous battery power to support active memories;
this power drain must be offset with a maintenance-float charger, periodic charging
or disconnecting the battery to prevent the establishment of irreversible crystallized
sulphation in the battery plate oxide. Failure to address this destroys battery capacity
and voids the warranty, as this is not a warranted defect in materials or workmanship.

Figure 1 shows the relationship between
Open Circuit Voltage (OCV) and State of
Charge (SOC) for the ODYSSEY®battery.
(A) How do I know the state of charge
of the battery?
Figure 1: ODYSSEY®battery OCV vs. SOC
As long as the battery has not been
charged or discharged for 6 or more hours,
Figure 1 can be used to determine the
SOC of the ODYSSEY battery. Use a high
quality digital voltmeter to measure its
OCV. The graph shows that a healthy,
fully charged ODYSSEY battery will have
an OCV of 12.84V or higher at 77°F (25ºC).
(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% SOC) 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.

MAINTENANCE
ODYSSEY®batteries are very different from standard flooded batteries that are openly
vented. The ODYSSEY battery is and operates as a sealed battery, recycling nearly all
gases internally under normal operating conditions. There is no corrosion of the positive
terminal or corrosion to the surrounding area. ODYSSEY batteries are shipped fully
charged from the factory, but prior to installation, check the battery’s voltage to see if it is
12.65V or greater. If not, recharge it using the procedure below.
Do not charge in an air tight compartment.
Never attempt to remove the top decal cover, as it will cause the battery to fail.

CHARGING
The SOC in an ODYSSEY®battery can be determined from the following chart:
*Cold Start Performance S.A.E. J537 June 82
** Pulse Current
Operating temperatures from -40°F (-40°C) to 140°F (60°C)
To get long life from the ODYSSEY battery, it is important that the battery is kept near full
charge, approximately 12.8V. If there are electrical loads during storage, then the negative
battery cable should be disconnected or an independent float charger used. Low power
2.0 amp chargers for storage charge will keep a fully charged battery fully charged but
cannot recharge if the ODYSSEY battery becomes discharged.
Racing Vehicles using total loss (no alternator) - standard automotive type chargers
are not designed to return 105-108% of the energy removed. They normally boost charge
to 80-95% and expect the alternator to complete the charge. EnerSys®recommends
using approved chargers that provide 105-108% recharge before switching to storage
charge. The EnerSys approved chargers are listed on www.odysseybattery.com.
To fully charge a 31-PC2150 and 31-800 battery that is routinely discharged deeply,
a minimum of 40 amps are required with charger voltage within the range of 14.1V to
14.7V. It is imperative not to exceed 15.0V as this will cause the pressure valves to open
and out-gas hydrogen, oxygen and water from inside the battery. This will shorten the life
of the battery and cause premature failure. Some portable chargers exceed 15.0V, especially
two-wheel garage chargers, so charging voltages should be verified by measuring the
charging voltage during the time when the charging amperage is reducing from full out-
put. The deep cycle charging voltage must be within 14.1V minimum to 14.7V maximum.
If a standard automotive charger is used to boost charge a discharged battery because
of an accessory left on, it is important to make sure the charging voltage does not ex-
ceed 15 volts during charge. A hand held voltmeter can be used to monitor this periodically.
WINTER STORAGE

10 11
Winter Storage
The ODYSSEY®battery does not lose its charged energy during cold storage tem-
peratures, so there is no need to trickle or float charge during winter months. To store
off-season, measure the battery voltage to make sure it is fully charged, 12.84 volts or
greater; recharge if necessary. Disconnect the negative battery cable to prevent any ap-
plied electrical load during storage. The ODYSSEY battery cannot freeze down to -40°F
(-40°C), so it can be left in the vehicle. It can be stored for 2 years or more below 77°F
(25°C). Charging is required at 2 years or 12V, whichever comes first.
A 12V, 2 amp trickle charger can also be left connected to the battery if it is kept in stor-
age for extended periods or if the battery is subject to parasitic loads during storage.
The trickle charge voltage measured at the battery terminals must be between 13.5V and
13.8V. We recommend using the ODYSSEY battery charger for your battery. Additional
information on ODYSSEY battery chargers, where to buy ODYSSEY battery chargers and
ODYSSEY battery charging in general can be found on our website at
www.odysseybattery.com.

36V BATTERY CONNECTION
To power a 36V trolling motor, you will need to connect three ODYSSEY batteries in
series. As shown in the bottom illustration, the negative of Battery 1 is wired to the
positive of Battery 2; the negative of Battery 2 is then connected to the positive of
Battery 3. Finally, hook up the positive terminal of Battery 1 to the positive terminal
of your trolling motor and the negative terminal of Battery 3 to the negative terminal
of the trolling motor.
24V BATTERY CONNECTION
To power a 24V trolling motor, you will need to connect two ODYSSEY®batteries in
series. As shown in the top illustration, the negative of Battery 1 is wired to the positive
of Battery 2. Hook up the positive terminal of Battery 1 to the positive terminal of your
trolling motor and the negative terminal of Battery 2 to the negative terminal of the
trolling motor.
