Batteries Plus carries them. The one in my camera was the Energizer L544. Duracell model is the X28LB which is a Lithium-Ion Battery. https://www.batteriesplus.com/productdet... Make sure you only use a 6 Volt, there are a lot of similar sized batteries which are other voltages such as 3 or 12 volts. You do not want to ruin your camera.
