Car Battery Maintenance Guide
Regular Maintenance Steps
-
Visual Inspection
Check for signs of corrosion, damage, or leakage. Look for bulging or cracking in the battery case.
-
Clean Battery Terminals
Remove corrosion using a wire brush and baking soda solution. Ensure terminals are tight and clean.
-
Check Electrolyte Levels
For non-sealed batteries, check and top up distilled water if needed. Never use tap water.
-
Test Battery Voltage
Use a multimeter to check voltage. A healthy battery should read around 12.6V when fully charged.
-
Inspect Battery Hold-Down
Ensure the battery is securely mounted to prevent vibration damage.
Safety Warning:
Always wear protective gear when handling batteries. Remove metal jewelry and work in a well-ventilated area. If unsure, seek professional help.
