| Cycle Application |
| 1. Limit initial current less than 2.25A. |
| 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 0.054A 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 13.6to 13.8 volts with current limit2.25A 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
