Ideas on how someone could intentionally wreck a car battery?
My dad go his tires changed the other day, and they came in telling him that his two month old battery needed to be replaced. He said no because it was new, they insisted, then he asked for the manager and let him have it. He got the car back later, and it was fine. The next morning, it wouldn't start. He jumped it and got it started, then let the engine run for a while to recharge.
The car now starts, but voltage is so low that every light, the air conditioner, the radio, etc. Have to be turned off. Then it takes a while for any lights to come on.
So I think the manager or one of the workers got pissed at my dad, and did something to the battery. Before, it was able to run a 12v air co
pressor for a solid 20 minutes and still start up without a problem, and now it barely even starts and refuses to charge.
Btw, we have checked and water levels are fine, and there are no ibvious signs of it being swapped out.
Might just be paranoia talking though
