3 - 58CHKADJCHECKING THE BATTERYCharging method using a constant voltage chargerMeasure the open-circuitvoltage prior to charging.Connect a charger andammeter to the battery andstart charging.NOYESIs the amperage higherthan the standard chargingamperage written on thebattery?Charge the battery until the chargingvoltage reaches 15 V.Leave the battery unused for more than 30minutes before measuring its open-circuitvoltage.12.8 V → Charging is complete.12.0 ~ 12.7 V → Recharging is required.Under 12.0 V → Replace the battery.This type of battery charger cannotcharge an MF battery. A variablevoltage charger is recommended.Leave the battery unused formore than 30 minutes beforemeasuring its open-circuit voltage.NOTE:Set the charging time to amaximum of 20 hours.NOTE:Constant amperage chargers arenot suitable for charging MFbatteries.CAUTION:ChargerAmmeterVoltmeter
