I love these batteries, and I've been buying them for a few years now. They're always charged up and ready to go, unlike NiCd and NiMH batteries which tend to decay and lose capacity between charges. This means I can charge up the Eneloop batteries when I find a dead one, put it in my battery drawer, and not have to worry that it might be dead when I need it. I recently found an un-opened pack of Eneloop batteries with a receipt from 2015, and the batteries were just as usable as a fresh pack of alkaline batteries.
