How do you know if you need a new car battery?

Answer 1

That is a 50/50 chance. A battery bought in 2003 might be still good today, while a battery bought 3 months ago might go bad.

Asking how do you need to know if you need a car battery is like asking when you tire will go flat if you running it too low. You just don't know, however if you turn your car over and it seems like it is cranking over for a few times before it starts, take your car to a garage that specializes in auto electrics and batteries. They will usually test your battery and charging system for free. Another way is to take the battery itself to a car parts store and they will usually test it for free as well.

Some other reasons a car won't start may be nothing to do with the battery at all, such as a faulty starter solenoid or starter motor or some loose wiring or a faulty ignition coil.

Regarding the battery, another possibility is that a it can lose its charge and die if the car has been in stilling or storage for a long period of time without having regular top-up charges.
