Judgment Of Charge Completion
- Specific gravity of electrolyte should be held within the specific range of 1.250 - 1.290 for one hour or more.
- Voltage while charging should be held within the specified range of 15.0 - 16.8 V for one hour or more.
- Gas is actively generated in all cells.
- The amount of charge reaches 1.2 - 1.5 times of the amount of discharge.NOTE: The amount of discharge/charge can be calculated by the following formula.
Amount of discharge (Ah) = remaining capacity calculated by specific gravity (%) x 5 hour rate capacity (Ah)
Amount of charge (Ah) = Charging current value (A) x Time for charging
