Four-pack BP-511/BP-511A replacement kit

This Kastar kit supplies four lithium-ion BP-511/BP-511A batteries and an AC wall charger. Each cell delivers 7.4 volts and 2600 milliampere-hours, matching the original Canon specification. The pack suits owners of compatible EOS, PowerShot, Optura and ZR-series cameras who need spare power for extended shoots. No proprietary protocols or firmware locks are involved.

Wall charger thermals and power draw

The included charger accepts AC 100 to 240 volts at 50 to 60 hertz and outputs DC 8.4 volts at 600 milliamperes. A foldable flat plug keeps the unit compact during storage. An LED shows red while charging and turns green when the battery reaches full charge or stands by. Operation remains silent and generates minimal heat under normal indoor use.

2600 mAh capacity per cell

Each battery stores 19.24 watt-hours at 7.4 volts, giving a 2600 milliampere-hour rating. This figure determines how many frames or minutes of video you can capture before swapping cells. Cameras that require higher-capacity packs or proprietary communication chips will not gain extra runtime from these units.

Questions about this item

How do I install the BP-511A batteries into my Canon EOS 5D and what step is often missed?

Slide each 7.4 V 2600 mAh pack into the camera's battery compartment until the latch clicks; the step users miss is fully seating the contact side before closing the door.

What maintenance will the four Li-Ion packs and the AC wall charger need over time?

Store packs at roughly half charge if unused for months, recharge every three months to 19.24 Wh, and keep the charger's foldable flat pins clean and free of dust.

What limit appears first when I shoot continuously with these 2600 mAh batteries?

The 19.24 Wh capacity sets the runtime ceiling; sustained high-drain shooting will deplete the 7.4 V cells before thermal limits are reached.
