The great mystery of NiMH high-capacity vs. low self-discharge, answered
NiMH batteries are cool, but they are expensive. If you really want to "go green"* and switch wholesale to NiMH, it's a significant investment and you want to get the best stuff you can afford. I know a lot of people out there don't know if they should go for "high-capacity" NiMH or "low-discharge" NiMH. I know it caused me a lot of consternation when I needed to replace my older cells - none of which were low-discharge type, so I had no experience to go by. Here's my take: Low-discharge, hands down. This is based on my experience - no formal tests, but the experience is so compelling I don't think it's even worthwhile testing. Many of my NiMH batteries go into my SLR flash. Obviously I do not use my camera every day, and it sometimes sits for weeks. I also obviously want to be able to pick it up at any time and go to it, which I often do for work purposes.
