I recently bought a 2001 4dr 4wd s-10 blazer with 40,000. miles. Last Sunday, afternoon, I went to start it, and all I got was a clicking sound, and after a few times it turned over enough to start. I drove about 25 miles that evening and the next morning, it hesitated when I turned the key before turning the engine to start......yesterday, it would barely start (lots of clicking before finilly starting)....It also wanted to stall for the 1st 1/2 mile or so when coming to a complete stop. (Additionally the clock on radio had reset to default of 1:00) I drove it about 60 miles with out any problem, and all gages were right where they should be, and after the several stops I made it started just fine, instant turn over with key. the truck sat from about 10 am to 7 pm, and it was just about dead again. (clock back to 1) again it charged on the 60 mile trip home, but was dead again this morning. It appears that the battery is the origional that came in the truck new.
Do batteries just die all of a sudden like this, or is there something else draining it when the truck is parked. it seems to be charging just fine, but won't hold a charge for more then a few hours. I checked everything I could think of the might be draining it, but didn't find anything unusal.....any input would be greatly appricated.
