Compact Design with Safety Protections

The battery measures 3 by 2 by 1 inches and fits directly into the camera body or compatible Canon chargers CB-5L and CG-580. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current, and over-heating during daily handling. Cells meet UL1642 and CE safety standards for reliable operation. The lithium-ion chemistry avoids memory effect across repeated charge cycles.

Efficient Power Delivery

Rated at 19.24 Wh, the pack supplies consistent energy for typical photo and video capture without excessive heat buildup. Lithium-ion cells maintain stable voltage output through most of the discharge curve under normal use. No active cooling is required, keeping the camera silent during operation. The protection circuitry limits current draw to safe levels automatically.
