What is the capacity of a car battery?
1 Answers
Generally, the capacity of household car batteries ranges between 54-60Ah. Car battery capacity refers to the amount of electricity the battery can discharge under certain conditions (discharge rate, temperature, termination voltage, etc.). Functions of a car battery: It supplies power to the starting system, ignition system, and electronic fuel injection system during engine startup; provides power to car electrical equipment when the engine is off or at low idle; acts as a voltage stabilizer for the vehicle's electrical system; and stores excess electrical energy generated by the alternator. Maintenance of a car battery: Avoid parking the car in open parking lots for extended periods. If long-term parking is necessary, remove and take the battery to prevent freezing damage; car batteries should be charged regularly as prolonged disuse leads to gradual self-discharge, eventually causing failure. Therefore, start the car periodically to recharge the battery; clean the battery terminals regularly and apply special grease to protect the wiring harness; frequently inspect battery accessories and connecting circuits; avoid using car electrical appliances after the engine is turned off, as using the battery alone when the engine is not generating electricity can cause damage.
