Cycle Application
1. Limit initial current less than 16.25A.
2. Charge until battery voltage (under charge) reaches 14.1V to 14.4V at 25ºC(77ºF )
3. Hold at 14.1V to 14.4V until current drop to under 0.42A for at least 3 hours
4. Temperature compensation coefficient of charging voltage is -30mV/ºC
Standby Service
1. Hold battery across constant voltage source of 13.6 to 13.8 volts with current
limit 16.25A continuously .When held at this voltage , the battery will seek its
own current level and maintain itself in a fully charge status.
2. Temperature compensation coefficient of charging voltage is -18mV/ºC.

NOTE : The battery should be charged within 6 months of storage, Otherwise, permanent loss of capacity might occur as a result of sulfation
