2004 Century battery totally dead, fully charged 1 min. after jump

[blowout preventer]

2004 Century was totally dead after church, no crank, no horn. Made
sure it was in park. All I noticed with the key in ON position was the
indicator LED by the A/C button dimly lit.
Hooked jumpers onto it, let it sit like that less than a minute, tried
starting it and it popped right off.
Unhooked cables and drove it home, literally two blocks, shut it off
and tried starting it again, and it cranked right over like nothing was
ever wrong.
What would have caused that? I suspected the battery at first since
it's an '04 and original battery, but it starts fine ever since.
Anything to do with that chip in the ign key?

Good chance it was a dirty connection. Putting the cables on it may
have been just enough to jiggle it for a better connection. Take the
cables off and clean them.

If the battery is truly eight years old, it is not going to last much
longer. I don't know what your driving conditions are, but I'd
probably replace it now rather than have to go dead in the middle of a
rain storm at night. It may last two more day, two more moths, two
more years. Do you want to take the chance? Comes down to how much
of a value you put on peace of mind. Even if you have AAA or other
road service, do you want to wait for the to show up?
