2. The engine won’t crank (and the accessories and lights are off)
This symptom points squarely at a flat battery – just as with the above scenario, there could be a number of causes. Battery damage as a result might mean it needs to be replaced too.
3. You've had to jump start your car a lot
If you have had to jump start your car
a lot, there is obviously a problem with your car. A slow power drain or a failing alternator could be the culprit, but there is a chance the repeated jump start has damaged the battery, so you might also have to replace it.
4. Your car battery is cracked, swollen or leaking
If you notice the battery case is cracked or swollen, or you see battery acid leak, you will certainly need a new battery. The replacement battery must be of the right size and type, with the posts in the right place and enough power (expressed in CCA, for cold cranking amps) to start your car. Cold cranking amps (CCA) refers to the amount of power needed to start a cold engine. The colder the engine, the more power required to start it. If you live in a cold climate, you will need a battery that can generate enough CCA to always start your engine.
