I've just bought my first nitro model, and would welcome advise on a
number of topics. To start the ball rolling, what are the best strength
of battery to by for the handset. I've seen AA 2500mAh to 2900mAh and
the prices range from £3 to £4.50 for 4. Is it money well spent to by
the 2900mAh? or am I better baying twice the number of 2500mAh?
