While alkaline batteries are suitable for use in the COOLPIX 990, battery
life can be extended by using high-capacity lithium or nickel-metal hydride
(Ni-MH) batteries.
The following techniques can be used to extend battery life:
• Turn the LCD monitor off whenever possible (see right). Turning the
monitor off eliminates the single biggest draw on battery power.
• If the batteries become exhausted, try turning the camera off and warming
the batteries gently, for example in an inside pocket. The batteries may
recover sufficient charge for a few extra shots with the monitor turned
off.
• Use the AC adapter (available separately) when the camera is connected
to a computer, when playing images back, or when using the slide-show
option.
In M-REC mode, power consumption is also affected by the options in the

sub-menus (see table below).
