Charging Procedure


Charging Procedure

1. A battery with a built-in hydrometer showing a green dot does not require charging unless the battery has just been discharged (by cranking the engine).
2. Connect the battery charger cables to the positive and the negative battery terminals. Make sure all charger cable-to-battery terminal connections are clean and tight.

IMPORTANT: Do not use the charge settings for jump starting the vehicles.

3. Charge the battery using the charge setting for 12 VDC batteries that gives the highest charge rate to the battery. Refer to the battery charger manufacturer's instructions.
4. Charge the battery until the green dot appears in the hydrometer. Check the battery every half-hour. The battery may need to be tipped or shaken gently in order for the green dot to appear.
5. After charging, test the battery. Battery Load Test
