While Charging

TOOLS REQUIRED
GM P/N 12303040 Battery Side 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 adapter should be snug against the battery terminals to keep resistance to a minimum.

NOTE: Refer to Fastener Notice in Service Precautions.

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.
