Is It Normal for Charging Batteries to Heat Up?
1 Answers
It is normal for charging batteries to become slightly warm, but if they become excessively hot or too hot to touch, that is abnormal. Battery maintenance methods include: 1. When the ammeter indicates insufficient charge, recharge promptly; 2. Avoid parking the car in an open parking lot for extended periods. If long-term parking is necessary, remove and take the battery to prevent freezing damage; 3. Start the car periodically to recharge the battery; 4. In winter, car engines are harder to start. Each attempt should not exceed 5 seconds, with at least 15 seconds between attempts; 5. Avoid using car electronics after the engine is off, as using the battery alone without the engine generating power can damage it; 6. Clean the battery terminals regularly and apply special grease to protect the wiring harness.
