the blog shows it went in last July. I'm not impressed with that battery life. Worst of all, it uses a special battery.
When digging through our electronics box recently I was reminded I had a battery that looked similar. Miraculously, it was a perfect match. I used one of these batteries for my Camaro's key fob, probably in 2007. I knew I held onto the other one for eight years for a reason. Hopefully that 2011 expiration date is overly cautious. Since it's a name-brand, I hope it lasts longer than the original.
