Car Battery Replacement
You didn’t leave a car door open or a light on. (We believe you.) But your vehicle just won’t start. You turn on the ignition, and all you get is the tell-tale clicking noise. Possibly followed by competing pronouncements of “Your battery’s dead” and “It’s your alternator” from anyone within earshot.

WHY WON’T MY CAR START?
- Your battery is drained (but healthy): It’s the best-case scenario: you accidentally left on your lights, or some other battery-draining feature. A jump start will send you on your way, lesson learned.
- Your battery is too old to hold a charge: It’s time for a new battery. If your jump start fails – or your car won’t start the next day – have your battery tested.
- Your starting system needs service: It’s not your battery. There’s a mechanical problem preventing ignition, draining your battery, or keeping your battery from charging as you drive.
Why won’t my car start if it’s not the battery?
Hold a charge
Why won't my car battery hold a charge?
From the easiest-to-fix to the most complicated, here are the most common reasons your vehicle’s battery can’t hold a charge:
- Corrosion around the battery terminals: Your Auto 8 technician will visually inspect these during every Auto 8 Courtesy Check and can clean away corrosion safely.
- Something’s draining your battery: Check every light switch, door (liftgate included), and lighted compartment in your vehicle. You may be leaving a door slightly ajar, or a faulty latch could appear closed but is allowing your lights to stay on overnight.
- End of battery life: Every car battery has a finite charging capacity, testable with a voltmeter machine.
- A bad alternator: The alternator is responsible for recharging your battery as you drive, so it’s one of the first mechanical problems to check.
- Other defective vehicle parts: From the fuses to the serpentine belt.
About Car Battery Replacement
FREQUENTLY ASKED QUESTIONS
A car battery should be replaced when its capacity has dropped below 12 volts — which happens to most batteries after three to seven years of use. Here are some signs that your battery is running critically low:
- Your battery won’t accept a charge: You hear rapid clicks instead of your engine cranking — and jump-starting doesn’t help. You’ll need a new battery to get rolling again.
- Your battery can’t hold a charge: Jump-starting works, but you have to jump-start repeatedly. Replace your battery as soon as you can. You’re at risk of being stranded.
- Your battery shows low voltage on a voltmeter.
Request a car battery check appointment at the first sign of trouble starting your vehicle (unless you drained the battery by accident, and a jump start solves the problem indefinitely). Your Auto 8 technician will test your battery’s voltage with a voltmeter and help you select a new battery if the time has come. If your battery’s healthy, we’ll diagnose the real problem.
You’ll get the most thorough testing by having your vehicle towed to Auto 8. If you remove your battery and bring it to Auto 8, we can test it — but we won’t be able to test your charging system. (That’s the next step if we find your battery is in good shape.)
Most car batteries last from three to seven years, depending on climate and driving patterns. With such a long time window for your battery to potentially fail, it’s smart to incorporate battery testing into your regular maintenance cycle. Don’t get stranded!
At Auto 8, it takes 20-30 minutes to replace a car battery on most vehicles. Our battery replacement service includes cleaning the battery tray and terminals to get rid of battery acid and other debris. We also recycle your old battery.
Your vehicle owner’s manual will tell you what size battery you need. Your Auto 8 technician can answer any questions you have about the battery specifications for your make and model.
