Two-pack Li-Ion replacement

This Kastar two-pack supplies BP-511 and BP-511A compatible lithium-ion cells rated at 7.4 V and 2600 mAh for 19.24 Wh each. They fit a long list of Canon EOS, PowerShot, Optura, ZR and DM series cameras as well as the BP-508, BP-512, BP-514, BP-522 and BP-535 battery models. The pack suits owners who need spare power for extended shoots.

Replaces ageing original cells

The batteries substitute for depleted OEM packs used with Canon CB-5L and CG-580 chargers. The jump is worth it when your current cells no longer hold a full day’s charge or when you want a second set ready for travel. Built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating helps extend cycle life.

Check camera and charger model

Verify that your camera appears in the supported model list covering EOS 5D, 10D, 20D, 20Da, 30D, 40D, 50D, 300D, D30, D60, Kiss and the many PowerShot, Optura, ZR and DM variants. Confirm your charger is a CB-5L or CG-580 so the new cells will charge correctly.

Questions about this item

Will the 3*2*2 inch BP-511 pack fit inside my EOS 5D battery compartment?

The two Li-Ion cells measure 3 by 2 by 2 inches, matching the original BP-511 form factor used in the EOS 5D, 10D, 20D, 30D and other listed models.

How do I install the batteries, and what step do people often miss?

Slide each pack into the camera until the latch clicks, then charge fully on a CB-5L or CG-580 charger before first use — skipping that initial full charge is the common mistake.

When will the 2600 mAh cells need replacing, and how can I extend their life?

Expect several hundred charge cycles; store at roughly half charge in a cool place and avoid letting them drop to zero to maximise usable lifespan.
