Can a Car Battery That Doesn't Hold Charge Be Repaired?
1 Answers
Car batteries that don't hold charge can be repaired. Here are the details: 1. If the issue is insufficient electrolyte, you can add distilled water or purified water to the battery. However, tap water should not be used as it can cause severe self-discharge of the battery. 2. If the battery voltage is insufficient, below 11V, you can use a repair device's high-resistance repair function to raise the voltage above 11V, which is necessary for charging. If the battery voltage is below 10V and cannot be improved through charging or repair, the battery must be replaced. 3. If the electrodes are sulfated, this condition cannot be repaired, and the battery needs to be replaced. If the battery is aging, it is also recommended that the owner replace it as soon as possible. 4. The battery is a crucial component of the car, and regular maintenance should be observed. 5. Long-term parking can cause the battery to lose charge or become damaged. If the car needs to be parked for an extended period, the battery's electrode cables should be disconnected to avoid complete discharge. Try not to leave the car unused for more than 10 days. For long-term parking, the car should be started approximately every 5 days, keeping the engine idling to allow the alternator to charge the battery.
