Three-pack BP-511/511A replacement set

This three-pack supplies three 7.4V lithium-ion batteries rated at 2600mAh and 19.24Wh each. They replace Canon BP-511, BP-511A and related BP-series packs for a wide range of EOS, PowerShot and MV-series cameras. The pack is aimed at photographers and videographers who want spare cells for long shooting days.

Suits owners of listed Canon models needing

The set fits the cameras and chargers named in the compatibility lists, including EOS 5D, 10D, 20D, 30D, 40D, 50D and many MV camcorders. It is not for users whose camera requires a different battery form factor or voltage, or for buyers who want a charger included in the box.

2600mAh capacity at 7.4V

Each cell delivers 2600mAh at 7.4V for 19.24Wh of energy. That single figure determines whether the runtime meets your shooting needs. The batteries also carry UL1642 and CE marks with built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection.

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 battery into the grip until the latch clicks; the step people miss is confirming the 7.4 V label faces the contacts so the protection circuit aligns correctly.

What maintenance will these 2600 mAh Li-Ion packs need over time?

Store at roughly half charge in a cool place, recharge every few months to avoid deep discharge, and replace the set when run-time drops noticeably below the rated 19.24 Wh.

What limit appears first during continuous shooting with these 19.24 Wh batteries?

The over-heating protection circuit will cut power before the cells reach thermal limits, so sustained high-drain use stops when the pack temperature triggers the built-in safeguard.
