6.1 - TEST PREPARATION
1. Checkthatthebatterycablesareingoodworkingcondition.Replaceany
damagedorbrokencables.
2. Checkthatallterminalconnectionsaretightenedtopropertorque
specicationasdescribedinTABLE 2.
3. Fully charge batteries.
4. Let batteries rest for at least 8 hours once charging is complete.
6.2 - OPEN CIRCUIT VOLTAGE TEST
1. Checkandrecordopencircuitvoltage(O.C.V.)ofeachbattery.
2. Ifallofthebatteriesarebelow6.1V(6Vbattery),8.1V(8Vbattery)or12.2V
(12Vbattery)thesethasfailed.Replacetheentiresetofbatteries.Inthis
situation,thebatterysethadeitherprovidedallofitsavailableenergyorwas
severleyabused.
3. Otherwise,anybatterythatis0.25Vlowerthanthehighestbatteryvoltage(6V
battery),0.35Vlowerthanthehighestbatteryvoltage(8Vbattery),0.5Vlower
thanthehighestbatteryvoltage(12Vbattery),mighthavefailed.Makenoteof
these batteries.
Allbatteriesinagoodsetshouldbeabove6.4V(6Vbattery),8.5V(8Vbattery),and
12.7V(12Vbattery)whenfullychargedafteratleast8hoursofrest.
6.3 - DISCHARGE TEST (if you do not have a discharger, proceed to section 6.4)
1. Connectandstartdischarger.
2. Recordminutes(runtime)whendischargeiscomplete.Correctruntime
minutesforbatterytemperatureusingthefollowingformula:
Mc = Mr [1 - 0.009 (T-27)]
Where Mcisthecorrectedminutes,MristheminutesrecordedandT is the
temperatureattheendofthedischargein°C.
