How Long Should You Drive to Charge a Dead Car Battery?
1 Answers
A dead car battery typically requires about 4 hours of driving to fully recharge. Here are some precautions for car battery usage: 1. Turn off all lights before shutting down the engine. Older car models do not support automatic power-off after engine shutdown, so manually turn off headlights and interior reading lights before shutting down. 2. Turn off the air conditioning and audio system before shutting down. The air conditioning system involves the compressor and blower, and the audio system is also a high-power electrical device. If not turned off before shutdown, they will automatically start the next time the car is turned on, placing a heavy burden on the battery and causing damage. 3. Avoid leaving the car parked for extended periods. The battery installed in the car will self-discharge over time when left idle. It is best to drive the car at least once a week, with a trip duration of at least 20 minutes, to allow the battery to recharge while driving. 4. Close all windows before shutting down the engine. The power for operating car windows and sunroofs comes from the battery, so it is advisable to close all windows before shutting down the engine.
