Charging Procedure

1. Batteries with a built-in hydrometer showing a green dot do not require charging unless they have just been discharged (by cranking the engine).

Battery Charging:




2. Connect the battery charger cables to the positive (+) and negative (-) battery terminals. Make sure all charger cable-to-battery terminal connections are clean and tight.
3. Charge the battery using the charge setting for 12 VDC batteries that gives the highest charge rate to the battery.

Important
^ Do not use the charge settings for jump starting vehicles.

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 for the green dot to appear.
5. After charging, the battery should be tested.
