Battery Charging

1. Use a charger, with an end voltage of 16 V, equipped with a voltmeter that is accurate to within 1 percent.
2. The ambient temperature should be 15-38°C (60-100°F). A battery that is extremely cold will not accept measurable current for several hours after starting the charger.
3. Ensure that the charging area is well ventilated.
4. Do not charge the battery when the built in hydrometer is clear or yellow (C). Replace the battery if there is a cranking problem.
5. Do not charge a battery that appears to be frozen. Replace the battery.
6. Batteries showing a green dot in the hydrometer (A) do not need to be charged unless the battery has just been discharged (such as cranking the engine).
