Two-pack lithium-ion batteries for Canon cameras

This set includes two 7.4 V 2600 mAh lithium-ion cells and a matching AC wall charger. The batteries replace Canon BP-511 and BP-511A packs used in a wide range of EOS, PowerShot and Optura models. Photographers who need spare power for long shoots will find the twin-pack convenient.

19.24 Wh capacity decides runtime per charge

Each cell stores 19.24 Wh at 7.4 V, giving roughly the same shooting time as an original Canon BP-511A. The charger accepts 100–240 V AC input and delivers 8.4 V at 600 mA, so a full recharge takes several hours. Buyers who need faster turnaround or higher-capacity cells should look elsewhere.

Charger plugs directly into a wall socket

The foldable flat plug lets the unit sit flush against the outlet without a separate cable. A red LED shows charging and green shows standby or full charge. The only common issue is inserting a battery backwards — the contacts are keyed, but forcing it can bend the pins.
