[Elecraft] NiMH Battery Question

[n2htt at optonline.net]

I've been looking around for this info and throught someone on the list must know:

1) What is the full charge voltage for a AA NiMH battery? I'm guessing about 1.275v, since the pack of 8 I just got for my K1 had a starting voltage of 10.2v or thereabouts.

2) At what voltage is it recharge time? The pack has dropped to about 9.8v after about 6 hours, seems to be still going strong.

3) I have a solar panel that puts out  250ma in full sun. Since these batteries are rated 2000mah, can I just hook the pack up to the solar cell to charge. I've done some reading and that seems to be the conclusion, but somehow it seems too easy.

Thanks for the help
