While Charging

TOOLS REQUIRED
GM P/N 12303040 Battery Terminal Adapters

1. Do not charge a battery with a green hydrometer dot unless it has just been discharged, such as in cranking.
2. When charging, the adapters should be snug against the battery terminals to keep resistance to a minimum.
3. Make sure all battery terminals are clean and tight.

Tighten
Tighten the battery side terminal adapters to 15 N.m (11 lb ft).

4. Best results occur when charging a battery that is at room temperature. A battery that is extremely cold may not accept current for several hours.
5. Charge the battery until the hydrometer has a green dot.
6. Inspect the battery every half hour after starting the battery charger.
7. Tap the hydrometer lightly to dislodge any air bubbles. The bubbles may cause a false indication.
8. After charging, load test the battery.
