[QUOTE="WayneF, post: 514223, member: 12496"] Many battery brands license the Eneloop technology now. PowerEx is the Maha brand, and they have a version of these. [URL="http://www.mahaenergy.com/batteries/"]Batteries - Maha Energy[/URL] Imedion is Maha's version of Eneloop. They have both. Imedion is PowerEx Imedion, but there is also PowerEx, which is not that type. Note this Maha link says PowerEx discharges 1% per day (regular NiMH), and their Imedion retains 85% charge after one year (which is Eneloop type). That is a huge difference. This does come at the cost of a slightly lower total capacity. And both are considered good, but PowerEx (like all regular NiMH batteries) will self discharge and be dead in a couple months of storage. Imedion and Eneloop will still be good to go in a year or two. This seems an important property. Of course, this makes little difference when recharging today for a big session tomorrow. But a big deal when we get it out each Christmas for pictures. It's good when it still works But there are still lots of batteries that are not this low self discharge type (still regular old NiMH). IMO, any new batteries we buy should say words like low self discharge, or precharged, or mention a year or two of shelf storage. Eneloop and Imedion are top choices. [/QUOTE]
