Kastar BP-511A battery kit

This Kastar kit supplies two lithium-ion batteries and an AC wall charger for older Canon EOS and PowerShot cameras. Each cell delivers 7.4 V and 2600 mAh for 19.24 Wh of capacity. The bundle suits photographers who still shoot with models such as the EOS 40D, 50D or 300D and need reliable spare power.

Replaces ageing BP-511 cells

The pack substitutes worn original BP-511 or BP-511A batteries that no longer hold a full charge. It also covers compatible types including BP-508, BP-512, BP-514, BP-522 and BP-535. The upgrade is worth it when your current set drains quickly or the charger has been lost.

Simple wall charging with LED status

The charger plugs directly into 100 to 240 V mains and uses a foldable flat pin for compact storage. A red LED shows charging while green indicates standby or full charge. Insert each battery in the correct orientation; the only common issue is reversed polarity preventing the light from lighting.

Questions about this item

What are the dimensions of the included BP-511 batteries?

Each battery measures 3 by 2 by 2 inches, matching the original BP-511 form factor for Canon EOS 40D, 50D and 300D bodies.

How do I connect the AC wall charger to mains power?

Unfold the flat plug, insert it into a 100-240 V AC socket, then place a battery in the slot; a red LED shows charging, green shows full.

When should I replace the two 2600 mAh lithium-ion packs?

Replace them when run-time drops noticeably or after roughly 300-500 full charge cycles, whichever comes first.
