Dirty contacts can affect battery performance. - Bettery performance decreases with temperature. In cold environments, we recommend keeping spare batteries in a warm place, such as the inside of a coat. Batteries can recover their power when they warm up. - When Ni-MH batteries are charged for the first time, they need more than one charging to be fully charged. Charge fresh Ni-MH batteries at least two or three times before usage. - Keep battery and camera contacts clean. Dirty contacts can affect battery performance. - Performance of Ni-MH batteries may lessen it they are recharged repeatedly without making full-use. Discharge them fully before re-carging. - Refer to the instruction manual for the battery charger in advance.
