I recently bought a new battery. 2 days later i let my brother use it and he forgot to turn off the lights. So this it starts, so he got a car for him to jump start but the guy reversed the wire. Negative to positive and vice versa. Had the car towed home and i checked out the fuses and it was blown. So okay, no big problem not mad or anything i changed the fuse 100A and jump start it and it works fine.

Now this morning, i tried starting my car but no jump. I had 2 jump start it for it to work. Now this is a new battery and i still have warrenty. So should i go get another battery or is it something else?

 

if all your connections are good and it still dont start with that battery then put it in a different car and see if it starts if not the the battery is dead it might need to be charged....but you have warranty so u should just get a new one just to be safe

 

Since you still have warrenty I would go and get a new battery....
