The best thing about Eneloops do not seem to leak. I can just leave them in rarely used electronic devices without worrying. They might discharge, but so far this has never been a problem.

I don't think that I've ever seen any NiMH leak. If you look at teardowns - it's maybe not even possible. They look rather dry inside.

I've been using NiMH AA batteries for over 20 years. I've never had one leak. It's not unique to Eneloop.

Mentioned this above - so happy we went with Eneloops. Our battery waste is nearly 0, and no leaking..
