Before you start
- Do not use open flames or other fire hazards near the battery.
- Battery electrolyte contains dilute sulfuric acid; wear protective goggles and rubber gloves.
Procedure
- Check the electrolyte level; correct level is between LOWER LEVEL and UPPER LEVEL lines.
- For batteries without level lines, keep the fluid about 10 to 15 mm above the top of the plates.
- If the fluid level is low, remove the caps and add distilled water to the proper level.
- Measure the specific gravity of the electrolyte at 20°C [68°F].
- If specific gravity is lower than 1.22, charge the battery.
