anyone have battery problems??

[WannaXP8]

So ive had this problem two times now, so heres what it does, like everything will be fine..forever, and then all of a sudden, like it will go completely dead, so dead that it cant even be jumped, like the lights wont even go on, when you open the door, and you change the battery and its all good again, tell it did the same thing again last night..the first battery lasted like 80,000 miles, and the last one only lasted like 20,000, its like it frys the cells inside the battery..

sound like a bad batt. make sure to check the alt.

i would put my money on the alt. sounds like its not charging the batt. could also be a combination of the 2.

when a alt goes bad at the shop we always suggest on replacing the batt. at the same time.
They go hand and hand

The connection is probably just bad at the posts...try cleaning up the terminals.
