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

This pack supplies four lithium-ion batteries rated at 7.4 V and 2600 mAh each, plus a matching AC wall charger. It is built for owners of compatible Canon EOS, PowerShot, Optura and ZR cameras who need spare cells for extended shooting sessions. The bundle replaces single original batteries and proprietary chargers with one compact kit.

Charger thermals and power profile

The wall adapter accepts 100–240 V AC input and delivers 8.4 V at 600 mA, so it runs cool during typical charge cycles. A foldable flat pin keeps the brick slim for travel and reduces strain on sockets. LED indicators show red while charging and green when cells reach full capacity or standby.

Upgrade path and limits

The set replaces individual BP-511, BP-511A, BP-508, BP-512, BP-514, BP-522 or BP-535 cells and works with CB-5L or CG-580 charger bases. It suits photographers who want multiple ready spares without buying OEM packs separately. Buyers needing higher capacity per cell or USB-C charging should look elsewhere.

Questions about this item

How do I install the BP-511A battery and avoid the common polarity mistake?

Align the three gold contacts on the battery with the camera's contact strip, then slide the pack in until the latch clicks; the keyed shape prevents reverse insertion but forcing it can bend the pins.

When will the 2600 mAh Li-Ion cells need replacement?

After roughly 300 to 500 full charge cycles the capacity drops below 80 % of the original 19.24 Wh, so plan on new packs every two to three years with regular weekend shooting.

What thermal limit appears first during long video recording on an EOS 5D?

The charger's 600 mA output means a fully depleted 2600 mAh pack needs over four hours to recharge, so downtime between shoots becomes the practical bottleneck before the cells overheat.
