01 gagt 59k miles, about a month ago battery started dying slowly, got a charger and it did a desulfidation cycle on it and charge and it seemed to bring it back to normal. it had been fine up until end of last week with hot weather and it all of a sudden was a slow barely starter again. yesterday the battery would not start the car so i jumped it fine. stopped by pep boys on the way home from work (at which time it did start by itself barely) and picked up a new energizer battery. now the interesting part, when removing the factory battery last night, when i went to remove the positive terminal, the lead female donut terminal and surrounding plastic on the battery actually broke off with the terminal. inside the screw in terminal end was rusted/corroded together to that piece. based on this corrosion, this obviously had been going on for awhile, and i assume just got so bad that it was cutting off the proper amount of current i could get to start the car. i have never seen a failure like this and am curious what could've caused it and if anyone else had a failure like this. as well, acid was able to easily spill out then from this broken off spot. luckily i was able to remove the terminal bolt from the broken piece, pulled it apart, baking soda'd any acid corrosion, sanded the terminals clean, and hooked up new battery and all is perfect. just curious of this failure. and disappointed in only getting 4 years out of a factory battery.
