What do you people think?
They sound like a good idea, though i imagine they take a good while to charge!

EDIT: Just realised theyre AA and not AAA :(

Found them for $27.50 free shipping on Amazon for the charger and 4x AA: http://www.amazon.com/PowerGenix-ZR-PGX1HRAA-4B-Charger-Rechargeable-Batteries/dp/B0029NZVZ0 or with 8AAs for $38 shipped: http://ecobatteries.net/Powergenix-5Hour-Fast-Charger-with-8/M/B002WLP69U.htm?traffic_src=froogle&utm_medium=organic&utm_source=froogle . Might be good for a TX that you use a lot!

It looks like they plan on making AAAs soon: "Charger will charge 123or 4 AA NiZN batteries or 1 or 2 AAA NiZN batteries independently"

I'm not buying it... I've have some nimh cells for years now and as long as they are charged properly, they last a long time. Sure, some of the punch goes out of nimhs over time, but I usually retire the AAAs to TV remotes, or whatever other household duties I can find.

I think the issue some have with nimh cells is that they just let them sit too long uncharged, and some of the usual store-bought chargers are just crap. The general public doesn't worry about delta-peaks and discharge rates though... if the article would have shown some graphs and numbers, I might be interested.

Regardless, I'm sure we'll see them popping up in MiniZs soon enough though.
