My nimh AAA batteries do not seem to be giving as much voltage as they used to. Is there a way to fix this?

over time rechargeables die out and give less and less power. and then you buy new ones. they just wear out. if you were to 'fix' a battery, that would involve fooling around with the mixture of stuff inside (sry, I can't translate chemistry). you might try completely discharging and fully recharging a coupla times, but you can't 'reboot' a battery so to speak.

If you have a "smart" charger that can do so, try conditioning the batteries, a couple of times if necessary.

How do I completely discharge my batteries?

Hrrmm I will consider investing in a smart charger, I thought mine was when I bought it but I was wrong.

I'd guess you could put a wire in connecting the + and - terminals. And then make sure the battery doesn't get too hot.

I take it you're using them in a PCDP or something, right? just use them till it cuts out, then wait some time and do it again (it'll work again for a couple of seconds), two or three times and they should be completely drowned.

I'm just guessing "conditioning" does the same thing?

but anyway, even rechargeables aren't meant to last forever...

The batteries should last about 400-500 charges which is more than a year or 2 depending on your use.

This is considered the best charger:

Here is a FAQ page that deals with NiMH batteries and conditioning.

How do I condition stuff manually? I'll get a new charger when I get some cash flow but until then..

They are fairly new 700mah batteries so I hope they still have a lot more charges in them. ^^
