NiMH will self-discharge pretty quickly. I bought a bunch for the boat,
but can only use them in things that I use a lot, and aren't critical.
For instance, don't put them in a flashlight you never use, and expect
it to work three months later. Stick with Duracells for those types of
uses. I use mine in my digital camera, some entertainment radios,
flashlights I use a lot, a coreless gangway light, etc. Other than
that, they are nice.
