How many years can a car battery generally last?
1 Answers
Automotive batteries typically last around 2 years. Functions of car batteries: Power the starting system, ignition system, and electronic fuel injection system during engine startup; supply power to vehicle electrical equipment when the engine is stopped or at low idle; act as a voltage stabilizer for the entire vehicle electrical system; store excess electrical energy generated by the alternator. Car battery maintenance methods: Clean the accumulated white acid corrosion powder on battery terminals to extend service life; add distilled water to the level between the upper and lower indicator lines; check whether the battery is charging normally.
