What current should be set for a car battery charger?

[DiKeegan]

The current of a car battery charger should be adjusted to one-tenth of the battery's capacity. The CCA parameter in the car's performance specifications represents the battery's maximum discharge current. The maintenance methods for the battery are: 1. Charge the battery promptly when the ammeter indicates insufficient charge; 2. Adjust the electrolyte density according to the standards for different regions and seasons; 3. Add distilled water or a special replenishing fluid when the electrolyte is low. The functions of the battery are: 1. It supplies power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. It powers the car's electrical equipment when the engine is off or idling at low speed; 3. It provides power to the electrical equipment when the generator's output is insufficient; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It stores excess electricity generated by the alternator.
