Knowing the signs of failing will help you know when to replace a car battery. Some of these signs are quite obvious, while others aren’t. Here are the signs you should look for, to know that it’s time to replace your car battery.
If almost every time you go to start the car in the morning, you either have to charge the battery or get it jump started, you may need a new car battery. Check the electrolyte level. If it’s low, refill it and recharge the battery fully. If this doesn’t help, you should probably replace the battery. This will fix the problem if the battery still has usable life in it. If not, it won’t help.
At least twice a month, you should use a tester to check whether your battery is capable of maintaining a charge under load. If not, you need a new car battery.
If during your routine maintenance electrolyte checks, you notice that you have to refill the battery cells with electrolyte, you most likely have either a leaking vent or a cracked case. If either of these are the case, you will need a car battery replacement.
If you have the post clamps as tight as they will go and they still wiggle or move, then most likely you have a broken terminal or post. You should replace this battery as soon as possible.
These are some of the most common problems that will cause you to need to replace a car battery.
