How to Determine When a Car Battery Needs Replacement?

[SanElliot]

To determine if a car battery needs replacement, check for insufficient charge or malfunction. Battery maintenance methods include: 1. Charge promptly when the ammeter indicates low charge; 2. Adjust electrolyte density according to regional and seasonal standards; 3. Add distilled water or specialized replenishing fluid when electrolyte is low; 4. Limit engine cranking to 5 seconds per attempt; 5. Start the car periodically if the battery is unused for extended periods; 6. Regularly check that the battery vent holes are clear; 7. Inspect terminals for oxidation; 8. Examine all electrical circuits for aging or short circuits.
