Direct Replacement

This two-pack of lithium-ion BP-511 batteries supplies 7.4 V and 2600 mAh each, totalling 19.24 Wh per cell. They replace Canon BP-511, BP-511A and several related packs in a wide range of EOS DSLRs, Optura camcorders and PowerShot G-series cameras. Photographers who need reliable spares for long shooting days will find the pair convenient.

Build Integration

The packs slot into the original battery compartment and charge in Canon CB-5L or CG-580 chargers without adapters. No firmware updates or menu changes are required, and the built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. Carrying two units frees you from hunting for a wall outlet during events or travel.

Thermals and Power

Normal operation stays within the cell’s rated voltage and capacity, and the protection circuitry limits temperature rise during continuous discharge. Lithium-ion chemistry avoids memory effect, so partial recharges do not reduce usable capacity. The packs deliver steady current for stills and video until the camera signals low power.
