Final Verdict Added 01/03/2013: After having used these batteries, along with some older Energizer, for some time I’m not left with the impression that they’re any better. Perhaps they perform better in a laboratory but I’ve found they’re just as likely to be discharged (or nearly discharged) as the Energizers when I need to use them and this is despite recharging all of the batteries at least a few times a year in an attempt to ensure they’ll be ready when I need them.
I’m not convinced that they’re worth the premium charge, especially since they typically have less capacity than similar batteries that cost less. As far as batteries are concerned they seem fine but I just haven’t had an experience that leads me to believe that they are superior.
It’s easy for me to remember the rechargeable batteries that my dad used to have. It seems that it took forever for them to recharge and they were much more expensive than current rechargeable batteries.
Several years ago I started using Energizer rechargeable batteries along with a charger by the same company. In general, I typically used them in digital cameras or entertainment remotes. They worked well though tended to discharge fairly quickly when not in use.
A couple of years ago my wife purchased a battery charger from my wish list, which has extended the life of the Energizer rechargeables. However, every once in a while I’d find a mention of the Sanyo Eneloop brand that caught my attention.
