Hi Yaniv,
If it is just one cell that you use, then a standard AA alkaline battery, say
Duracell, will have a rated voltage of 1.5 V, and rated capacity of 2,700 mAh,
and a 5 year shelf life. The maximum open circuit voltage is normally 1.56V, and
the recommended end voltage is 0.8V. It will operate efficiently at high or low
discharge rates
If you use an equivalent AA sized Ni-Cad rechargeable battery, (say a Sanyo
Cadnica High Capacity, one of the better brands) then the rated voltage will be
1.2V, and the capacity is likely to be 1200mAh. If you want to successfully
recharge it, then you should not allow the end voltage to fall below 1V. The
open circuit voltage will depend on temperature, and the time since last
charged.
NiMH rechargeables for AA, will be 1.2V, with a slightly higher capacity
(compared with a Ni-Cad) of 1500mAh.
You will not damage the Sharp MD (or any other MD) if you substitute a
rechargeable cell for the alkaline cell, but you may well find that the unit
does not work, because the voltage is too low, or it does not work for very
long, due to the reduced battery capacity, or it works in play mode but not in
record ,say, due to the inabilty of the rechargeable cell to deliver a high rate
of disharge.
The Sharp handbook on the MT161 is also completely wrong about batteries.
Best wishes,
