2007 Pontiac Wave LT, 4D Hatchback, Standard, Y4M/MLMSECTION Notes
- Batteries with the green dot showing do not require charging unless they have just been discharged, such as in cranking a vehicle.
- When charging sealed-terminal batteries out of the vehicle, install the adapter kit. Make sure all the charger connections are clean and tight. For best results, batteries should be charged while the electrolyte and the plates are at room temperature. A battery that is extremely cold may not accept current for several hours after starting the charger.
- Charge the battery until the green dot appears. The battery should be checked every half-hour while charging. Tipping or shaking the battery may be necessary to make the green dot appear.
- After charging, the battery should be load tested. Refer to Battery Inspection/Test .
