How to Maintain Battery Life?
2 Answers
Maintaining battery life can be achieved through the following methods: 1. Regularly clean the dust and oil stains from the car battery terminals, and apply special grease to protect the wiring harness; 2. Periodically inspect the accessories and connecting circuits on the battery; 3. Minimize the use of electrical equipment inside the car after the engine is turned off; 4. Check the car battery through the observation hole on the battery and replace it regularly; 5. Start the car periodically if it is not used for a long time. The functions of the battery include: 1. Providing starting current to the starter when starting the engine; 2. Assisting the generator in supplying power to electrical equipment when the generator is overloaded; 3. Supplying power to electrical equipment when the engine is idling; 4. Protecting the electrical appliances used in the car.
I've been driving for over 20 years, and car batteries can last five to six years—the key is maintaining regular usage. Leaving the car parked too long without driving can easily drain the battery, especially in winter when low temperatures reduce battery performance. I make it a habit to take a long drive once a week to allow the alternator to fully recharge the battery, avoiding only short trips. Cleaning the battery terminals is crucial, as corrosion can cause poor contact—use baking soda and a toothbrush to scrub off the green powder. I also bought a portable charger to occasionally plug in for maintenance, especially during idle periods. A voltmeter check can provide early warning of low voltage. If you notice difficulty starting, don't delay—replace the battery early to avoid getting stranded on the road. Regularly check the fluid level—older-style batteries require topping up with distilled water, but modern maintenance-free types are more convenient. Overall, developing small habits can significantly extend battery life and prevent the need for roadside towing.
