How Long Does It Take to Recharge a Dead Car Battery by Driving?

[McGarrett]

It takes about 1-3 hours of driving to fully recharge a dead car battery. Here is some relevant information about car batteries: 1. Definition: Under normal conditions where the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, a car battery can typically last for more than 3 years. If you notice that the battery isn't holding a charge, the starter is weak, or the headlights are significantly dimmer, you should remove the battery and charge it using a battery charger for 12-24 hours. 2. Principle: The battery uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
