Replacement for Canon NP-E3

The Green Extreme NP-E3 is a nickel-metal-hydride battery pack built to replace the Canon NP-E3 in compatible EOS-1D series cameras. It delivers 12V and 2000mAh capacity for extended shooting sessions. Photographers who need a reliable spare for long events will find it fits the original battery compartment directly. Users requiring lithium-ion chemistry or higher voltage platforms cannot use this pack.

Thermals noise and power draw

Internal smart chips regulate voltage and temperature during charge and discharge cycles to keep performance stable. The Ni-MH chemistry has no memory effect, so the pack can be topped up at any state without capacity loss. Normal use produces no audible noise and the cells maintain consistent output across the full cycle. Extreme ambient temperatures may reduce available runtime compared with rated figures.

Bundled accessories and software

The pack ships in packaging made from recycled materials, reflecting the supplier’s environmental focus. No charger, cable or firmware utility is included in the box. Buyers who need a dedicated charging station must source one separately. The one-year warranty covers defects but does not extend to accessories not supplied.

Questions about this item

How do I install the NP-E3 pack in my Canon EOS-1D and what step is often missed?

Slide the pack into the camera's battery compartment until the latch clicks; the step people miss is fully seating the contacts so the smart chip can regulate voltage and temperature.

What maintenance will this 2000mAh Ni-MH pack need later?

No memory effect means you can recharge at any level; store at roughly half charge if unused for months and recharge before the next shoot.

What limit appears first during continuous shooting with this 12V pack?

The 2000mAh capacity determines how many frames you capture before voltage drops and the camera shuts down.
