Q: At what percentage should a car battery be replaced?

Answer: You would rather be safe than sorry when it comes to your car battery, as it is best to avoid getting stuck without a functional vehicle due to a dead battery. Therefore, most mechanics will recommend that you get your battery replaced when it reaches 50% of its full capacity charge. However, this percentage can vary slightly depending on your car’s make and model, so it is best to consult your owners’ manual for clarification on when you should replace your battery. If you start to experience any signs that your car battery is dying or losing power, take it to get checked as soon as possible to avoid a dysfunctional car due to a dead battery.
