Questions about this item

How long will the 2600mAh rating actually power my EOS 40D in real shooting?

The 19.24 Wh capacity translates to roughly 2600mAh at 7.4V, giving extended run time for compatible Canon EOS and PowerShot models compared with standard packs.

Does the BP-511A interface limit charging speed on a CG-580 charger?

These cells work with Canon CB-5L and CG-580 chargers, and the built-in protection circuit manages voltage and current within the charger's normal limits.

Will the 3 by 2 by 3 inch pack fit the battery compartment of a PowerShot G6?

The BP-511/BP-511A form factor matches the original Canon battery dimensions, so it seats correctly in all listed EOS, PowerShot, Optura and ZR models.
