The first thing you should do
after buying a Nikon Coolpix 950/990 camera is to purchase Nickel
Metal Hydride rechargeable batteries. Nikon ships the camera
with non-rechargeable alkaline type batteries, which can be
exhausted in an hour of use. We recommend two sets of 1550 mAh
NiMH (Nickel Metal Hydride) rechargeable batteries and the quick
charger MH-C204F
from Maha. As soon as one set is exhausted we just swap them
and get back to shooting.
Another alternative is the Maha POWERBank
NiMH Battery Pack. This small device has 1800 mAh of power,
plugs into your cool pix through an external cable and will let
you shoot all day without interruption.
These are great power sources. But I have to admit,
besides the Maha batteries, I'm still carrying the original two
sets of rechargeable batteries and one hour charger I picked up at
Radio Shack on my way home when I first purchased the camera. Since I
also purchased a CoolPix 950, I'm now carrying two extra sets of
batteries.
