Charging Equipment

A battery charger that is considered sufficient is usually capable of a 16-volt output. when choosing a charger, the following items should be considered essential:
1. A 16-volt minimum output.
2. To prevent overcharging, the unit should have a timer (1 to 2 hours) or a voltage regulator that would regulate a maximum of 18 volts, or have an automatic shut-off feature at full charge.
3. Ammeter or charging rate meter.
4. An automatic polarity protector.

Some equipment that is available includes the AC Delco MP2101-07, Associated No. 6001, the Sun 720, or equivalent. Very few chargers have sensitive low-voltage meters, therefore, separate voltmeters may be necessary.

A suitable load tester such as the Sun VAT-40 (or equivalent) is available and is a very useful tool to properly diagnose battery problems.
