Thisphenomenon is referred to as "sulphation". Since thelead sulphate acts as an insulator, it has a directdetrimental effect on charge acceptance. The moreadvanced the sulphation, the lower the chargeacceptance.The below table shows the normal storage time orshelf life at various ambient temperatures.Temperature Shelf Life20 4 1 30.2 150 ( 32 F) to 20 ( 68 ) 12 months21 ( 70 ) to 30 ( 86 ) 9 months31 ( 88 ) to 40 (104 ) 5 months41 (106 ) to 50 (122 ) 2.5 months- o o o oo o oo o o oo o o oo o o oC ( F) to C ( F) monthsC C FC C C FC F C FC F C F- - -oRelationship of OCV and state of charge (25 C)oCharge CharacteristicsThe batteries in the ABT TS/TM...W product rangemust be charged at a constant voltage.The charging voltage of 2.27-2.30 v/cell should befor float charging.It is not necessary to limit the current as this willbe governed by the maximum output availablefrom charger until the voltage limit is reached.Maintenance is recommended as the batteryapproaches end of useful life used forfloat charging.To achieve nominal performance characteristics,it is recommended to adjust this value to suit theambient temperature, as indicated in thefollowing table:At an ambient temperature of 20 C.oTemperature Float charge Voltage5 2.36-2.39Vpc10 2.31-2.34Vpc20 2.27-2.30Vpc25 2.25-2.28Vpc30 2.23-2.26VpcoooooCCCCCTemperature Floating charge voltageOperatingOperating temperature rangeDischarge Charge Storage-20~60 -10~60 -20~60o o oC C CTS...W series0 2 4 6 8 10 12 14 16 18 20110100908070605040Capacity(%)Storage time: months13.51312.51211.5110 10 20 30 40 50 60 70 80 90 100Battery voltage(V)Relative state of charge(%)Life characteristics of standby useLife characteristics of standby use40 Co 30 Co20 CoTM...W series2.30V/Cell2.30V/Cell100%80%60%40%20%0% 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8Thousand cyclesD.O D. in%.120%100%80%60%40%20%0% 0 0.2 0.4 0.6 0.8 1 1.2Thousand cyclesD.O D. in%.11THUNDERTS ...W SERIESM/Operating |
