When should I replace my car's battery?
There's a quick test you can do on your own to test your battery health. Start the car about a dozen times. Every time it should start normally. If it it stops cranking and starts clicking and we know it's a weak battery. Here in the desert on a normal flooded battery we typically don't get more than about 3 years out of them due to the heat. So you should always have the battery tested and not just replace it.
