So, I've been recently stocking up on a whole mess of Eneloop NiMH - with the kiddos, I've probably got at least 75 of each AA and AAA batteries scattered among their toys and in storage for swapping out.
These are the standard capacity NiMH Eneloops. Great for toys, but my camera flash tends to chew through them pretty hard. So the other day, I stumbled upon the Ikea LADDA batteries. These are a 2450 mAh low self discharge cell, roughly equal in capacity to the Eneloop Pro's. So people did some digging, and they're made in Japan. Apparently, the only factory in Japan that makes a LSD NiMH cell is FDK, who also makes the Eneloop line. People have done a *lot* of testing - capacity, discharge curves, etc - and short of sneaking into the factory and looking, it appears that the Ikea LADDA cells are a rewrapped Eneloop Pro. The nice part is that while the Eneloop Pros run about $21 bucks for a 4 pack on Amazon, the Ikea branded cells run $7 for a 4 pack.
So I snagged 3 packs last time at Ikea over the weekend. Got them charged up, gonna slap them in the flash and see how they last. But from what I've been reading, they should run pretty well.
