when you drain a rechargeable NiMH battery fully with an LED light, it gets damaged? that's what someone said awhile ago. If true, does this also affect rechargeable alkalines and NiCad's?

It will definitely reduce the life of the rechargeable alkaline. Rechargeable alkalines should be refreshed while it's still basically fresh. NiCad and NiMH are both better recharged before reaching a state of being dead. In most cases you notice a degeneration of performance before it gets significantly below the proverbial one volt lower limit. If left on in a infrequently checked application, it can become exhausted, or even some LED lights with regulation can drain them too far down.
Usually in such a case a couple of charge discharge cycles will return them to a quality state.

If you have a 1700 mah NiMH, and you're only permitted to use a small number of those milliamps, then those milliamps aren't worth a plugged nickel, are they? NiMH was introduced as a replacement for NiCad, and are a resonable replacement only if it's power is as readily available. The tales of only being able to skim the mah off the top of NiMH's are greately exaggerated.
