• Beware of memory build up. This is mostly a problem with NiCd type batteries and not the NiMH batteries will retain a “memory” and if not allowed to go completely dead or completely discharged prior to charging they won’t be able to recharge fully. Read the information that came with your battery to see if discharging is required.

• Use your LCD sparingly. LCD panels gobble up a lot of battery power. If your camera provides both an optical and LCD viewfinder, try to use the optical finder as much as possible.
