The Canon BP-955 Intelligent Lithium-ion Battery Pack is a replacement battery made specifically for your Canon camera or camcorder. This smart 5200mAh pack can read the remaining battery life and communicate with your camera to indicate when the power is running low. Four LED lamps on the face light up to display the current battery capacity so youll always know when its time for a charge and when is okay to continue filming. The BP-955 is compatible with select Canon C and Canon XF Series cameras.
