As to rechargable AAA and AA I use 'Eneloop' batteries,

NiMH generally work well in devices that will tolerate low voltages.
Eneloop cells start out at about 1.5V and expected to work down to
1.2V.  Most of the meters and gadgets fail at 1.3V and below.  My
guess(tm) is that the meter starts to complain that it wants a charge
when about 40% of the capacity is still left in the battery.  Most of
the equipment I've seen is designed to use alkaline cells which has a
higher voltage range.

There are also consistence problems and matching issues with NiMH:

 Wow, some test site.
