Battery inspection and maintenance
1. Inspecting electrolyte levels
Electrolyte levels should be inspected at least once a month. Routine inspections are required by law (Road Transport Vehicle Act).
Inspect the electrolyte levels from the side of the battery
- If the side of the battery is dirty, clean the electrolyte level lines with a cloth dampened with water, and check that the electrolyte level is between the UPPER LEVEL and LOWER LEVEL lines.
Note: Do not clean the battery with a dry cloth otherwise static electricity may ignite and cause an explosion.
- When the electrolyte level is lower than half way between the UPPER LEVEL and LOWER LEVEL lines, immediately add purified water until the electrolyte level is at the UPPER LEVEL line. When finished, ensure that the vent plug is tightly fastened.
- For details, refer to the battery user's manual or the car's maintenance guide book.
2. Exterior inspection
Visually inspect the battery exterior
- Check the container for cracks, breaks, and leakage, and check that the exhaust hole of the vent plug is not clogged up with dust or dirt.
- If you find anything unusual, consult with the battery distributor.
3. Inspect for loose clamps or terminals
Check that the clamps and terminals are secure
- Inspect the clamps
Inspect the battery to make sure that it is secured by clamps. If loose, tighten the clamp nut until the battery is securely fixed in place.
- Inspect the terminals
Check that the connection between the battery terminals and the cable terminals on the car are tightly secured. If loose, tighten the terminal nut until the cable is securely fastened. If there is corrosion, remove it with a wire brush.
