Looking to buy some rechargeable batteries for digital camera

What size? AA?

LSD NiMH are quite good if you want to leave them in the camera for
months and be sure they'll still be ready when you turn it on for that
critical shot.

is there a
limit on the mAh level or should I just go for something like 4300 mAh
for better/longer lasting power.

Above a certain capacity, the numbers turn to fiction, for AAs that
number's probably about 2900 now.
