Before charging the batteries, inspect the plug of the bat­tery charger and vehicle receptacle housing for dirt or debris.

Charge the batteries after each days use. Monthly

• Inspect all wiring for fraying, loose terminations, corrosion or deterioration of insulation.

• Check that the electrolyte level is correct and add suitable water as required.

• Clean the batteries and wire terminations.

The correct level of the electrolyte is 1/2" (13 mm) above the plates in each cell (Ref Fig. 18 on page 15).

This gas is hydrogen which is lighter than air. Water and sulfuric acid droplets will be carried out of the battery vents by the hydrogen gas; however, this loss is minimal. If the battery electrolyte level is too high, the electrolyte will block the vent tube and the gas will force it out of the vent tube and battery cap. The water will evaporate but the sulfuric acid will remain where it can damage vehicle components and the storage facility floor. Sulfuric acid loss will weaken the concentration of acid within the elec­trolyte and reduce the life of the battery.

Over the life of the battery, a considerable amount of water is consumed. It is important that the water used be pure and free of contaminants that could reduce the life of the battery by reducing the chemical reaction. The water must be distilled or purified by an efficient filtration system. Water that is not distilled should be analyzed and if required, filtration installed to permit the water to meet the requirements of the water purity table (Ref Fig. 19 on page 15).

Electrolyte level should be at least 1/2" (13 mm) above the plates and 1/4" to 3/8" (6 to 10 mm) below vent

Plates

This level will leave approximately 1/4" - 3/8" (6-10 mm) of space between the electrolyte and the vent tube. The electrolyte level is important since any portion of the plates exposed to air will be ruined beyond repair. Of equal importance is too much water which will result in electrolyte being forced out of the battery due to gassing and the increase in volume of the electrolyte that results from the charging cycle.

Even if the water is colorless, odorless, tasteless and fit for drinking, the water should be analyzed to see that it does not exceed the impurity levels specified in the table.

Automatic watering devices such as the one included in the E-Z-GO Battery Maintenance Kit (P/N 25587-G01) can be used with an approved water source (Ref Fig. 20 on page 16). These watering devices are fast and accu­rate to use and maintain the correct electrolyte level within the battery cells.

Do not overfill batteries. The charging cycle will expel electrolyte and result in

caution

component damage.

Unless the electrolyte is at or below the plates, all watering should be done after charging.

A battery being charged will 'gas' with the majority of the gassing taking place at the end of the charging cycle.
