Important: Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis.

5.Wait 5 to 10 minutes after filling the battery cells. Add distilled water, if necessary, until the electrolyte level is up to the Upper line (Figure 36) on the battery case.

6.Install the battery vent caps.

Charging the Battery

Charging the battery produces gasses that can explode.

Never smoke near the battery. Keep sparks and flames away from battery.

Important: Always keep the battery fully charged (1.260 specific gravity), especially when the temperature is below 32°F (0°C) to prevent battery damage.

1.Remove the battery from the chassis; refer to Removing the Battery.

2.Check the electrolyte level; refer to Checking the Electrolyte Level.

3.Make sure that the vent caps are installed in the battery, and charge it for 1 hour at 25 to 30 amps or 6 hours at 4 to 6 amps. Do not overcharge the battery.

4.When the battery is fully charged, unplug the charger from the electrical outlet.

5.Disconnect the charger leads from the battery posts (Figure 37).
