I have a lab scale that uses 8 alkaline AA batteries, and it quit working a few days ago. Turned out the batteries were dead, a bit too soon.
But what's worse is that at least one of the cells leaked badly. I had the 8-cell battery holder in a plastic bag, so the corrosives were not able to get anywhere vulnerable, but these batteries were installed in July 2011, and are marked as good until March 2014.
I think I heard on the web of similar experience with Kirkland. In any event, I've thrown all Kirkland batteries out.
