General Procedure

TOOLS REQUIRED
- GM P/N 12303040
- J 42000 Digital Battery Tester
- For best results, use an automatic, taper-rate battery charger with a voltage capability of 16 Volts.




- A battery showing a green dot in the hydrometer (A), does not need to be charged unless the J 42000 battery tester has shown that the battery needs to be charged.
- A battery showing a dark dot in the hydrometer (B) should be charged unless the J 42000 battery tester has indicated no charge is needed.
- Do not charge a battery when the built in hydrometer is clear or yellow in the center (C). Tap the hydrometer lightly in order to dislodge any air bubbles. The bubbles may cause a false indication. If the hydrometer is still clear or yellow, replace the battery.
- The charging area should be well ventilated.
- Do not charge a battery that appears to be frozen, a low the battery to warm to room temperature and test it before charging.
