I just stopped by a store after work to pick something up. I pulled up and turned off the car. I was gone for about 1 minute. When I got back to the car, it wouldn't start. This has never happened before.
When I popped the hood, there was a bunch of blue powder around the positive terminal of the battery. I cleared most of it away with a cloth while waiting for someone to give me a jump. I got a jump and drove home and turned off the engine. I immediately tried to start the car again and it wouldn't start.
Do I need a new battery? How much do they cost? Can I install it myself? I have a 99 Mazda Protege that I bought second-hand about three years ago.
Mostly I get around by bike, so I am not sure what to do or if I'll be able to afford this.
