Man, I have had a ton of problems with Nimh batteries and are disgusted with them. I've had numerous packs fail over the past few years, and they were ''quality'' batteries maintained by a very good charger. I'm done with them.

Buy up some good old fashioned nicads before the supply dries up. That's what I did. (They are doing away with them...)

Nicads good, NiMH bad.

I've disposed of tens of the rechargable types for my cameras too and other electronics. Nothing but problems with them.
Hmmmmm ... guess I have not seen that be the case if proper capacity and correct impedence NIMH batteries are used in the first place. Cell selection is much more critical with NIMH batteries than with NiCds. Both types of cells have been around long enough now and both have more than proved their worth.
In most cases, users went out and bought high capacity, high impedence NIMH batteries, fryed them a few times on a charger then wondered why they didn't work so well. In some cases these same batteries couldn't supply the current they needed from day one because the user chose to use the wrong battery for the application. Simply stated, NiCd batteries are a bit more tolerant to abuse and for a given cell size, usually have a lower impedence. As a result, many users get along better with NiCds than they do NIMH batteries.

I was always thankful that I didn't sell batteries to the RC community and I'll leave it at that.
