3 - 58CHKADJCHECKING THE BATTERYCharging method using a variable voltage chargerMeasure the open-circuitvoltage prior to charging.Connect a charger andammeter to the battery andstart charging.Is the amperage higherthan the standard chargingamperage written on thebattery?NOYESChargerAmmeterAdjust the voltage to obtain thestandard charging amperage.Set the timer to the chargingtime determined by the open-circuit voltage.Refer to “CHECKING THEBATTERY”.Adjust the charging voltage to20 ~ 25 V.Monitor the amperage for 3 ~5 minutes. Is the standardcharging amperage exceeded?NOYESIf the amperage does notexceed the standard chargingamperage after 5 minutes,replace the battery.If the required charging time exceeds 5 hours, it is advisable to check thecharging 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 itsopen-circuit voltage.12.8 V → Charging is complete.12.0 ~ 12.7 V → Recharging is required.Under 12.0 V → Replace the battery.Leave the battery unused formore than 30 minutes beforemeasuring its open-circuit voltage.Set the charging voltage to16 ~ 17 V. (If the chargingvoltage is lower, charging willbe insufficient, if it is higher,the battery will be over-charged.)NOTE:NOTE:
