Can Maintenance-Free Batteries Be Topped Up with Electrolyte?

[LeGenesis]

Maintenance-free batteries cannot be topped up with electrolyte, as they are factory-sealed with the appropriate electrolyte solution. The functions of a car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the vehicle's electrical equipment when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the alternator's output is insufficient; 4. Cushioning voltage surges in the electrical system to protect the vehicle's electronic components; 5. Storing excess electricity generated by the alternator. Battery charging precautions: 1. Always charge the battery while it is connected to avoid data loss from disconnection; 2. A battery voltage 10% below the rated voltage indicates undercharging; 3. Prevent water from entering the battery during charging.
