Constant – Voltage Charge

Cycle application 1. Limit initial current less than 30A.
2. Charge until battery voltage (under charge) reaches 14.1V to 14.4V at 25℃( 77F) .
3. Hold at 14.1V to 14.4V until current drop to under 0.72A for at least 3 hours.
4. Temperature compensation coefficient of charging voltage is -30mV/℃.
Standby service 1. Hold battery across constant voltage source of 13.6to 13.8 volts with current limit 30A
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/℃
NOTE : The battery should be charged within 6 months of storage, Otherwise, permanent loss of capacity might occur as a result of sulfating.
