Martin,
Tom Moore who is a test engineer for medical and military battery packs
wrote recently on a RC web site that the chief reason NiMh false peak is
the wrong charge rate. They should be charged at close to 1C or the
peak may not be detected.

That's worth knowing. Thanks. Do you know how he is detecting the peak
(i.e. voltage or involution)?

I've just upped the rate to 1C charge (2.4A) and 0.2C (0.5A) discharge on
the Prodigy II and am running a couple of cycles.

He also mentions that they should never be
left on trickle charge for an extended time and that trickle charge as a
regular charging method will eventually destroy them.

Noted with thanks.

I have had good luck with Sanyo Eneloops 2000 mAh.

Looks like I need to get a set. I did a search and found a lot of good
experiences being reported. What charge conditions are you using for them?
