[ale] [OT] any experience with low self discharge NIMH batteries

[Brian Mathis]

I am using some Eneloops and they are pretty nice.  I have them in
some motion-sensing night-lights in high-traffic areas, so they are
used frequently.  I recharge them every few months, but have not
actually seen them completely die.  Overall I'm very happy with them.
