I. INTRODUCTION
ODYSSEY®batteries are manufactured by EnerSys®using its unique Absorbed Glass Mat (AGM) Thin
Plate Pure Lead (TPPL) technology to deliver twice the power and three times the life of conventional
AGM batteries.
Bringing together the technologies incorporated into ODYSSEY batteries and NorthStar batteries has
integrated years of intelligence, research and development, resulting in the creation of the next
generation of AGM - TPPL batteries. AGM2is a unique design of Valve Regulated Lead Acid (VRLA)
batteries that combines three major technical advancements in one battery: super high-grade
materials + refined chemical formula + TPPL technology. This sets AGM2batteries apart in terms of
power, fast-charge acceptance, shelf life, durability and most of all exceptional value for your
investment.
Throughout their design cycle life, AGM2batteries can provide engine cranking pulses of up to 2700
amps for five seconds at 77°F (25°C), while delivering over 400 charge/discharge cycles to 80% Depth
of Discharge (DOD). This challenges all typical starting batteries, which are only designed for high cur-
rent for short durations, to perform poorly when deeply discharged repeatedly.
Likewise, a typical deep cycle battery, which is designed to provide relatively low current for a long
duration of time, cannot provide the high current bursts that are needed for starting applications.
AGM2technology allows one battery to provide both excellent cycling life and high-power capability
for many applications. AGM2batteries excel in both starting and deep cycling without compromising
lifespan or performance, making them an excellent choice for a wide range of applications such as
heavy-duty trucks, recreational vehicles, marine, emergency power and much more.

IV. GETTING STARTED
A. INSTALLATION
ODYSSEY®AGM2batteries are shipped from the factory at a full State of Charge (SOC) and should be
readyforinstallationoutofthebox.Intypicalstartingapplications,measurethebattery’svoltage;ifit
is12.65voltsorhigher,thebatterycanbeinstalled.Ifthevoltageislowerthan12.65volts,thebattery
should be charged. Multiple battery configurations should be matched voltage. Refer to the Charging
section in this manual if needed.
To replace an existing battery, follow the steps below:
  1. Besuretoweartheappropriatepersonalprotectiveequipment.
  2.Notetheorientationoftheexistingbattery’spositiveandnegativeterminals.
  3. Disconnectthecables,negativefirst,fromtheoldbatteryfollowingvehiclemanufacturer
guidelines if applicable. The old battery should be returned to a battery dealer for proper
recycling.
  4. Inspectthebatterycablesforcorrosion,aciddamageorinsulationdeteriorationandreplaceif
needed.

V. TECHNICAL DETAILS
A. OPERATING TEMPERATURE RANGE
Temperature impacts the life and performance of AGM2batteries,asitdoesallbatteries.Ingeneral,
higher temperatures reduce battery life while lower temperatures reduce the available capacity that a
 batterycanprovide.RefertoTable3belowfortheoperatingtemperaturerangeforeachmodel.

Like all batteries, it is best that AGM2batteries be kept at
ahighSOC.Itisimportanttounderstandhowto
determine the SOC of AGM2batteries correctly. The
approximate SOC value is found by measuring the
battery’sOpenCircuitVoltage(OCV)withahigh-quality
voltmeter. The voltage reading must be taken at least four
hoursafterthebatteryfinisheschargingoratleast30
minutes after it finishes a discharge. Measurements will
not be accurate if adequate rest time is not allowed.
Table 4 shows the typical relationship between OCV and SOC.
C. STORAGE AND SELF-DISCHARGE
Table 5

113°F(45°C) 6
Even if batteries are not installed in an
application and are being stored, their SOC
declines over time. The rate at which a
battery loses charge depends on the
temperature. The warmer the temperature
the shorter the storage time before a
freshening charge is required. Cooler
temperatures slow down the rate of
self-discharge. A good rule of thumb to use
isthatforevery18°F(10°C)riseintemperaturethestoragetimeiscutinhalf.Thismeansthatthe
storagetimeat95°F(35°C)ishalfthestoragetimeat77°F(25°C).
  Ifstoredat77°F(25°C)orlower,ODYSSEY®AGM2batteries should be given a freshening charge at
leastonceeverytwoyearsorwhentheOCVdropstoabout12.2volts,whichevercomesfirst.This

AMER-EN-IOM-ODY-0523
www.odysseybattery.com
OCV corresponds to a SOC of about 50%. Batteries should always be fully charged before they are
stored. The warmer the temperature the more frequently OCV should be monitored. Table 5 shows
how temperature impacts the rate of self-discharge.
D. BATTERY LIFE EXPECATIONS
Cycling Applications 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 charge. Design
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.
DOD is one of the main factors that determines how many cycles a battery can provide. 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generalrelationshipbetweenDODandnumberofcyclesisshownbelowinFigure1.HigherDODs
results in longer cycle life.

E. FLOAT APPLICATIONS
Batteries that are primarily used as a source of backup or emergency power are not frequently cycled.
The life of these types of applications is referred to as float life. Emergency lighting, security alarms
andUninterruptiblePowerSupply(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 float or trickle charge.
Since ODYSSEY®AGM2batteries are dual purpose by design, they offer a long-life battery option in
float applications. At room temperature (77°F (25°C)), these batteries have a design life of 10+years in
float applications. At end of life, an AGM2battery will still deliver 80% of its rated capacity.

F. CHARGING
  TherelationshipbetweencyclelifeandDODshowninFigure1holdsonlyifthebatteryisproperly
charged after each discharge. This means that each time the battery is discharged, between
103-105%ofthedischargedamphoursshouldbereturned.Forexample,if100amp-hourswere
dischargedfromthebatterybetween103-105amp-hoursmustbereturnedtothebatteryforafull
recharge. Failure to do so (over or under charging) will result in a loss of cycle life and ultimately a loss
of capacity. There are several ways to recharge batteries and the best way depends on how the
battery is being used.
Charging with an Alternator
  Whenusedinstartingapplications,ODYSSEY®AGM212-voltbatterieswillbechargedon-boardwith
astandardautomotivealternatorthatgeneratesanywherebetween14.2-14.5voltsat77ºF(25ºC).We
recommendatemperaturecompensationofthechargevoltageat±18mvperbatteryperºCvariation
intemperaturefrom25ºC.Thewarmerthetemperaturethelowerthechargevoltageandthecooler
the temperature the higher the charge voltage.
Charging with an A/C Powered Charger
  Whenusedincyclingorstand-bypowerapplications,anA/Cpoweredchargercanbeusedto
recharge ODYSSEY AGM2batteries. There are two main types of A/C powered battery chargers on
the market: full recharging ability or maintaining a full SOC.
  Inordertorechargeabatterythathasbeendischarged,itisbesttouseanautomaticchargerwithan
AGM setting that has the appropriate charge voltage and current per recommendations. For optimum
charging,thecurrentoutputshouldatleast40%ofthebattery’sC10rating.Thismeansabatterythat
hasa10-hourratingof100amphoursshouldbechargedwith40amps.Chargecurrentshouldnever
belessthan10%ofthebattery’sC10rating.Voltageshigherthan15.0voltswillcauseirreversible
damage to the battery. Please refer to Figure 2 below for a graphical representation of the
recommended charge profile for ODYSSEY AGM2batteries used in non-starting applications.
Figure 2
  ChargersthataredesignedformaintainingafullSOCareoftencalled“float”or“trickle”chargers
andgenerallysupplycurrentinthe0.5ampto1.5amprange.Thesechargersmightalsobecalled
maintenance chargers and are often used to maintain batteries that are used in seasonal applications
such as boats or RVs. These chargers are not suitable for recharging ODYSSEY AGM2batteries that
have been deeply discharged. However, they are suitable for maintaining batteries at a full SOC,
provided the float voltage setting is appropriate. The recommended float voltage for ODYSSEY AGM2

11
AMER-EN-IOM-ODY-0523
www.odysseybattery.com
batteriesis13.6voltsfora12-voltbatteryat77°F(25°C).
There are also chargers available that charge using constant current. These chargers do not have
multiple charge phases as shown in Figure 2. They simply supply current to the battery, which causes
the battery voltage to rise. Once the battery voltage reaches the setpoint for a fully charged battery,
the charging will terminate. How long it takes to charge a battery with this method depends on how
deeplythebatteryisdischargedandhowmuchcurrentthechargerprovides.SeeTable6belowas
anexampleofrechargingabatteryratedat100Ahfromvariousdepthsofdischargeusinga10-amp
constant current charger.

Temperature Compensation of Charge Voltages
Proper charging of all AGM2batteries requires temperature compensation of the charge voltage. This
is especially true in float applications where the batteries are on-charge constantly. The temperature
compensationcoefficientisapproximately±18mVper°Cvariationfrom25°Cper12-voltbattery.
Temperature and charge voltage are inversely related. Therefore, charge voltage must be reduced as
temperatures increase and charge voltage must be increased as temperatures decrease. Regardless
oftemperature,theminimumchargevoltageis13.2voltsaslowervoltageswilldamagethebattery
grids and shorten life.
Recovering a Severely Discharged Battery
Many commercially available chargers must detect a certain minimum voltage for the charging process
tostart.Thisisacommonsafetyfeaturetopreventusinga12-voltchargerona6-voltbattery.
Chargers of this type are unable to charge a battery that has been severely over-discharged. For
example,a12-voltchargermightnotstartthechargingprocessifthebatteryconnectedtoithasan
OCVof5volts.Dependingonthesizeofthebattery,therearetwowaystotrytorecoverthebattery.
   • Forbatteriesusedinstartingapplications,thealternatorcanbeusedtorechargethebatteryafter
jump-starting the battery to start the vehicle.
   • Forbatteriesnotusedinstartingapplications,asecondbatterythatisknowntobeatahighSOC
can be connected to the discharged battery in parallel. Refer to Section IV, B (Battery Sketch 2)
fordetailsrelatedtoconnectingbatteriesinparallel.Oncethelowbattery’svoltagereaches11.5
volts, the batteries can be disconnected from each other. The standard A/C
charger normally used by the system can then be connected to the battery that needs to be
charged. Please refer to “Procedure to Recover Deeply Discharged ODYSSEY Batteries”found
on www.odysseybattery.com for more details.
  Itisimportanttounderstandwhythebatterybecameover-discharged,sothesituationdoesnot
happen again. The most common reasons for batteries to be over-discharged are system issues
relatedtoparasiticloads(seepage13)ormalfunctioning/non-existentlowvoltagedisconnect
equipment.

Unfortunately,thisrecoveryprocessisnotalwayssuccessful.Whenbatteriesareseverelydischarged,
sulfation develops and can be very difficult to remove depending on how deeply the batteries
are discharged and how long they have been in that state. This condition is not warrantable
since it is the result of abuse or neglect in the application, rather than a manufacturing defect.
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chargersthatprovide105-108%rechargebeforeswitchingtostoragecharge.
Chargers approved by EnerSys are listed on www.odysseybattery.com.
TofullychargeanODX-AGM31andODP-AGM31batterythatareroutinelydischargeddeeply,a
minimumof40ampsarerequiredwithchargervoltagewithintherangeof14.1voltsto14.7volts.
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15.0volts,especiallytwo-wheelgarage
chargers,sochargingvoltagesshouldbeveriedbymeasuringthechargingvoltageduringthetime
when the charging amperage is reducing from full output. The deep cycle charging voltage must be
within14.1voltsminimumto14.7volts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exceed15.0volts
during charge. A hand held voltmeter can be used to monitor this periodically.

G. PARASITIC LOADS
  Inmanycasesbatteriesthatareapparentlyatrestmaybesupplyingasmallamountofcurrentto
connected equipment such as radios, clocks and security systems, to name just a few examples.
Today’svehicleshavemultipleon-boardelectronicsthatrequiresmallamountsofpower.Thesesmall
currents are collectively referred to as parasitic loads and may be detrimental to the life of a battery if
they are not accounted for in the design of the system.
  Overtimethesesmallloads–typicallytensofmilliamps(mA)–willconsumesignificantamphours,
which results in the battery voltage decreasing. Consider a boat that has a parasitic draw of 20mA and
isdockedforfivemonthswiththebatteryconnectedtotheload.Inthat150-dayperiodthatparasitic
load will consume more than 70 amp hours.
There are three ways to ensure that batteries are not being drained by parasitic loads in the system.
    1.Physicallydisconnectthebatteryfromtheloadafterfullychargingit.Amasterdisconnect
switch is also an effective countermeasure.
2. Periodically give the battery a freshening charge, using the charging guidelines outlined
onpage10.
    3.ConnectatricklechargerforAGMbatterieswhenthebatteryisstored,usingthecharging
guidelinesoutlinedonpage10.
H. TESTING
There are several different ways to test AGM2batteries. Depending on the time and equipment
available, one may choose to perform either a capacity test, a ½CCA Load Test or a Conductance
Test. These options should help determine whether the battery returned by the customer has reached
its end of life or simply needs a full recharge. For all methods, the battery should be fully-charged
before testing. The following includes details related to each test method:
RECOMMENDATION: Testing should be completed on a clean/main battery terminal surface, not
a steel stud. Testing batteries individually in multiple battery situations is best. At minimum, each
battery must be disconnected at one terminal (the same polarity).
1.Capacity Testing: This method tests the performance of the battery based on its Reserve
Capacity (RC) rating, which means the test may be more time consuming, however it is the
preferred test method for a state of health check. The equipment needed to perform this

AMER-EN-IOM-ODY-0523 www.odysseybattery.com
14
type of testing is called a discharger tester. The battery should be fully charged before using
this test method. Discharge testers are designed to apply a constant current load to a fully-
charged batteryuntilthebatteryvoltagereaches1.75voltspercell(10.5voltsperbattery)or
other appropriate end point voltageinlinewithpublishedperformancetables,whichis100%
discharged.Thelengthoftimethedischargetesterrunsuntil1.75voltspercellisreached
shouldbecomparedtothebattery’srated RC. Batteries that do not provide at least 80% of
their rated runtime are considered failed.
2. ½CCA Load Test: This method tests the performance of the battery based on its CCA rating
and is much faster than capacity testing. The equipment needed to perform this type of test is
called a ½CCA load tester. For accurate testing, the battery must be at least 75% charged,
which for AGM2batteriesmeanshavinganOCVof12.6voltsorhigher.
To perform the test, the CCA rating of the battery must be programmed into the tester. These
testersapplyhalfofthebattery’sCCAratingtothebatteryfor15seconds.After15seconds,
thebatteryvoltageshouldbeabove9.6voltsifthetemperatureis70°F(21°C)orwarmer;voltage
below 9.6indicatesafailedbattery.Fortemperaturesbelow70°F(21°C), refer to Table 7 on the
next page for voltage. Most of these testers will specify whether the battery passed or failed the
test. This can be an ideal test for batteries used in starter applications.
Temperature End of Test Voltage
70°F(21ºC) 9.60
60°F(16ºC) 9.50
50°F(10ºC) 9.40
40°F(5ºC) 9.30
30°F(-1ºC) 9.10
20°F(-7ºC) 8.90
10°F(-12ºC) 8.70
0°F(-18ºC) 8.50
Table 7
3.Conductance Test: This method tests the performance of the battery based on its level of
conductance. This is a fast test and is generally the type of test that will be used by auto parts
shops. The equipment needed to perform this type of test is a hand-held electronic battery
tester. There are a variety of hand-held testers on the market and most allow the user to
programkeybatteryparameterssuchasCCAandbatterytype.Ifthetesterhasanoptionfor
AGM2, it should be used, otherwise AGM is suitable. Like the ½CCA Load Test, the AGM2
batteryshouldhaveanOCVof12.6voltsorhigherbeforetesting.Aftertheelectronictestingis
complete, the tester will indicate whether the battery passed or failed.
I. MAINTENANCE
ODYSSEY®AGM2batteries are very different from standard flooded batteries that are openly vented.
These batteries operate as a sealed battery, which depend on internal recombination of battery
gasses under normal operating conditions. This means that there should be minimal corrosion of
terminalsoranypartofthesurroundingarea.Intheeventthatcorrosionispresent,itisbesttoclean
it off thoroughly by using a wire brush on any metal surfaces, and a wet rag anywhere else where there
areresidualsubstances.Itisalwaysrecommendedtouserubbergloveswhencleaningabattery.Do
not use chemicals to clean a battery, as some can damage to the plastic of the battery. There is no

15
AMER-EN-IOM-ODY-0523
www.odysseybattery.com
need to add water to the batteries. Opening the battery cover causes damage to the battery and voids
any warranty.
PLEASE NOTE: Perform periodic inspection for case damage, loose battery hold downs, loose
connections, corrosion and container swelling.
J. VENTILATION
ODYSSEY®AGM2batteries are part of a broader category of lead acid batteries called VRLA. This type
of battery depends on the internal recombination of battery gasses for proper operation. The internal
valveallowsfornearly100%recombinationofgasses,whichmeansthereisnoneedtoperiodically
add water.
WARNING: Any battery producing an odor or visibly venting should be removed from service.
Physically disconnect only after the area has been ventilated.
The high recombination efficiency of ODYSSEY AGM2batteries makes 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 stored, operated or
charged in a sealed or gastight enclosure. However, local regulations regarding ventilation must also
be followed.
K. Winter Storage
The ODYSSEY battery does not lose its charged energy during cold storage temperatures, so there
isnoneedtotrickleoroatchargeduringwintermonths.Tostoreo-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 applied 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twoyearsor
morebelow77°F(25°C).Chargingisrequiredattwoyearsor12.2volts,whichevercomesrst.
A12-volttricklechargercanalsobeleftconnectedtothebatteryifitiskeptinstorage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13.5voltsand13.8volts.Itisrecommendedto
use 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 at www.odysseybattery.com.
L. WARRANTY CONSIDERATIONS
ODYSSEY AGM2batteries are covered by warranty against defects in material and workmanship for at
least two years. Some models and applications are covered for longer. Please note that the following
actions will void any warranty coverage:
   • Removingthelabeledcover
   • Removingoralteringthebattery’sdatecode/serialnumber
   • Removingoralteringthebatteryterminal(s)
   • Openingthebatterycase

VI.ADDITIONAL INFORMATION
Should you need additional information, please contact your local Sales Representative or battery
supplier.OurTechnicalSupportgroupisalsoavailablebyphoneat[phone]andby
submittingaTechnicalInquirythroughtheContactUslinkonourwebsite.
VII. FAQS
Are ODYSSEY®AGM2batteries the same as Gel batteries?
No, these are not Gel batteries. These are absorbed electrolyte batteries, which means there is no
freeacidinsidethebattery;alltheacidisabsorbedintheglassmatseparators.Theseseparators
servetokeepthepositiveandnegativeplatesapart.InGelbatteries,theelectrolyteisinagelform.
What is the Ah rating?
   Theamperehour(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10.5voltsfora12-voltbattery.
Does mishandling the battery void the warranty?
The warranty applies to manufacturing defects and workmanship issues and does not cover
damages caused by customer mishandling.
What is the CCA rating?
Per SAE standard, the Cold Cranking Ampere (CCA) rating is the number of amperes a battery can
deliverfor30secondsatatemperatureof0°F(-18°C)beforethevoltagedropsto1.2voltspercell
or7.2voltsfora12-voltbattery.A12-voltbatterythathasaratingof550CCAwilldeliver550amps
for30secondsat0°F(-18°C)beforethevoltagefallsto7.20.
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fora12-volt
battery.A12-voltbatterythathasanMCAratingof725willdeliver725amperesfor30seconds
at32°F(0°C)beforethevoltagefallsto7.20.TheMCAissometimescalledthecrankingamperes
or CA.
What is the 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Ampere(PHCA)ratingdoesnothavean“official”
definition;however,itissuggestedthatfortrueautomotiveandmarinepurposes,a30-second
dischargeisunrealistic.ThePHCA,ashortduration(about3-5seconds)highratedischarge,ismore
realistic. Because the discharge is for such a short time, it is more like a pulse. The low impedance
of ODYSSEY battery technology allows them to maintain a higher voltage for more starter pulses,
resulting in less heating of starter motors and cables. Higher power output results in a faster start.
What is impedance?
The impedance of a battery is a measure of its internal resistance. The lower the battery impedance
the more the available power. The impedance of ODYSSEY®AGM2batteries is considerably
lower than that of a conventional automotive or marine battery. The high rate discharge capability
of ODYSSEY AGM2automotive and marine batteries is significantly higher than that of conventional
automotive and marine batteries.

What is Reserve Capacity (RC) rating?
The RC 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fora12-voltbattery.A12-voltbatterywithareservecapacityratingof100
willdeliver25ampsfor100minutesat80°F(27°C)beforeitsvoltagedropsto10.5.
What is the short-circuit current of these batteries?
Typically thousands of amps. As mentioned before, the AGM2batteries have a very low internal
resistance, which means that the short circuit current is very high. Precautions should be taken to
avoid short circuits as equipment and battery damage will occur.
What is the operating temperature range of these batteries?
   Theoperatingrangevariesbasedonthebatterytype.RefertoTable3onpage8fordetails.
Is the battery ruined if it is dropped?
   Itispossibletodamagetheinternalconnectionsaswellastheexternalcontainer,leadingtoa
damaged the battery. Batteries with visible external damage should not be used. Dropped batteries
should be tested prior to use.
VIII. DEFINITIONS OF ACRONYMS
AGM–AbsorbedGlassMatbattery.ThisisatypeofVRLAbatteryinwhichalltheelectrolyteinthe
battery is absorbed into the glass mat separator material.
TPPL – Thin Plate Pure Lead. This refers to the fact that these batteries are made of very thin plates,
which do not contain any calcium or other typical impurities that deplete battery voltage over time.
VRLA Battery – Valve Regulated Lead Acid Battery. These lead acid batteries are designed to include
pressurereliefvalvesthatallowfornearly100%recombinationofthegassesthatwouldventin
traditional flooded batteries. Because of this very efficient recombination process, there is no need
to periodically add water to these batteries.
OCV – Open Circuit Voltage. This is a voltage reading obtained from a battery that is not charging or
discharging. To get an accurate OCV on AGM2batteries, it is important to wait at least four hours after
chargingor30minutesafterdischargingtotakethevoltagereading.
DOD – Depth of Discharge. This is the measure of how many amp hours were taken out of a battery
comparedtothebattery’srating.Forexample,a100amp-hourbattery,whichhas40amp-hours
removed during discharge is said to be at 40% DOD.
SOC – State of Charge.Thelevelofchargeofabattery.Itcanbeapproximatedbyevaluatingthe
battery’sOCV.
