I've got an Energizer something-or-other battery in my Cavalier, it's been in there almost a year and replaced the original AC Delco battery that lasted the previous owner and myself a combined 7 years, before it died absolutely suddenly and abruptly. The car started fine, I shut it off, it would not start again with a jump. No matter how many times I jumped it and drove it after that, it would never charge.
Wife's car has an unknown age Kirkland (Costco) battery in it, that's almost dead because leaving her lights on seems to be almost a weekly occurrence.
