measuring its open-circuit voltage.

 

Ammeter

 

 

 

NOTE:

 

 

 

 

YES

Connect a charger and ammeter to the battery and start charging.

Is the amperage higher than the standard charging amperage written on the battery?

Set the charging voltage to 16 ~ 17 V. (If the charging voltage is lower, charging will be insufficient, if it is higher, the battery will be over- charged.)

NO

Adjust the voltage to obtain the standard charging amperage.

Adjust the charging voltage to 20 ~ 25 V.

YES

Monitor the amperage for 3 ~

5 minutes. Is the standard

 

 

charging amperage exceeded?

 

NO

Set the timer to the charging time determined by the open- circuit voltage.

Refer to “CHECKING THE BATTERY”.

If the amperage does not exceed the standard charging amperage after 5 minutes, replace the battery.

If the required charging time exceeds 5 hours, it is advisable to check the charging amperage after 5 hours. If there is any change in the amperage, readjust the voltage to obtain the standard charging amperage.

Leave the battery unused for more than 30 minutes before measuring its open-circuit voltage.

12.8 V Charging is complete.

12.0~ 12.7 V Recharging is required. Under 12.0 V Replace the battery.
