The KODAK PIXPRO WPZ2 operates using an LB-015 rechargeable lithium-ion battery. A USB cable and AC adapter are included in the box with the camera, allowing you to charge the battery in-camera. (The USB cable can also be used to connect your camera to a computer so you can transfer files from the micoSD card.) You may purchase additional batteries at https://kodakpixpro.com/shop/lb-015
