Okay so i accidentally popped my trunk and left it open for 2 days. Just found out about it today and threw a charger on it. Tried the terminal under the hood and a ground and my charger keeps turning off thinking its fully charged after about 10 min or so. So i pulled the back seat and hooked directly to the battery and still had the same problem. I reclosed the truck hoping maybe that was drawing of something but it's still shutting off saying charged. I tried both fast and slow charges. Any ideas? I've never seen drawing a battery dead once actually kill it. Thinking of pulling all connections and hooking the charger up to the battery directly seeing is something is drawing while its charging thats causing the problem. Hoping not to have to replace the battery. Any help would be greatly appreciated.
