What are some symptoms of a dead cell in a car battery?

I was trying to start my car yesterday but it wouldn’t. It seemed like it wanted to start but one of the cells might have been dead. What are some symptoms of a car battery with a dead cell?

Interestingly, some symptoms of a dead cell in a car battery are reminiscent of a dying car battery itself. If you get a dead cell in a car battery, it’s likely kaput, so watch out for these signs:
  • Your car struggles to turn over.
  • You have a lack of power to the accessories of the vehicle.
  • The battery has a voltmeter rating that’s less than 12.4 volts.
  • The car stops after you’ve been driving.
If you’re experiencing any of these symptoms, take your battery to an auto parts store for testing. They’ll be able to tell you quickly if your battery is bad or if you have a dead cell.
