How do I fix a car battery that won't hold a charge?
I need to jump my car every time I want to turn it on. I’d rather not replace the battery if I don’t have to. Is there a way to fix a battery that won’t hold a charge?

Batteries are not designed to last forever, and yours may simply be at the end of its life. That said, there are a couple of things to try to fix a battery that won’t hold a charge.
First, establish if the battery is salvageable. If you own a load tester, connect it to your battery. If the battery drops below 12 volts, it needs to be replaced.
The culprit may also be a faulty alternator. You can diagnose this by running the headlights—if their brightness slowly decreases, you have an alternator issue. This can spell larger car trouble, so you should get your alternator checked out by a mechanic.
A defective fuse can also be to blame. If you can identify the problem fuse and replace it, your battery could be back in action. This is a much cheaper fix than replacing the battery.
If the battery is at a functional voltage and these other issues aren’t to blame, you should try to
refill the car battery
