Many consider a vehicle’s engine to be its beating heart but without a working car battery, you’re not going anywhere. Once your motor begins to crank slowly, it’s time to get your hands on a new battery before you wind up needing a tow. And unless batteries are an area that you’re familiar with, it can be tough to understand how car battery performance figures relate to you. Whether you compete in car stereo contests or just want to heat your seat on a cold winter’s morning, there’s a battery for you.

You’ve got questions.The Autance has answers.

Q: How long does a car battery last?

Flooded batteries usually last 3-5 years, although their lifespans are getting shorter due to the heavier electrical load modern vehicles require. AGM batteries can last up to 10 years if well maintained.

Q: How do I know if my car battery is dying?

If your engine is slow to crank, then your battery is on the way out. Dim headlights are also a sign of a dying battery, as it can’t fully power all electrical components.

Q: Why does a car battery stop working?

Put simply, car batteries run out of juice over time. Other issues that could cause your battery to fail included corroded or loose battery connections, faulty electronics that drain the electrical system, and exposing your battery to extreme temperatures.

Q: How long does a car's battery last without driving it?

A: Normally, a new battery that's in good condition will last at least two to three weeks before it needs to be recharged by the generator. After about two to three months of non-use, a car battery will fully discharge.

Q: How much do I need to drive to keep my battery healthy?

A: You should drive your car for at least 30 minutes per week to keep its battery healthy, preferably at highway speeds.
