Direct replacement for Canon EOS 1D Mark II

The KingSener NP-E3 is a 12V 2200mAh lithium-ion battery built to replace the original pack in the Canon EOS 1D Mark II camera. It delivers 26.4Wh of capacity and is supplied new with a one-year warranty. Photographers who need a dependable spare for extended shoots will find it matches the factory form factor exactly.

Black Li-ion pack with integrated protection circuit

The unit uses high-quality cells and a built-in PCB that guards against overcharge and short circuits. Its physical dimensions mirror the OEM battery so it seats securely in the camera body and charger without modification. The black finish matches the original aesthetic and the cells are rated to meet or exceed the design capacity on every cycle.

12V chemistry limits runtime to camera demand

The 12V output is fixed by the NP-E3 standard so runtime scales directly with the camera’s power draw; heavy burst shooting or video will deplete the 2200mAh reserve faster than light use. Users should condition the pack with two or three full charge and discharge cycles at low current before relying on it. Storage above 80% charge in cool, dry conditions preserves long-term health.
