Canon CA-CP200L 14.4V 3400mAh Li-ion Replacement Battery

Canon EOS C70 / C80 / C200 / CA-CP200L — 14.4V Li-ion Replacement Battery

This is a 14.4V Li-ion replacement battery rated at 3400mAh (48.96Wh). It fits the Canon CA-CP200L, EOS C70, EOS C80, EOS C200, and eight additional compatible models. It replaces the original pack when capacity has degraded or a spare is needed for extended shoots.

• EOS Cinema and compact system fit: The C70, C80, and C200 share the same battery bay format and voltage rail. The BMS in each body handshakes at 14.4V with matching cell chemistry — this pack meets that requirement without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on Canon Cinema EOS hardware. The BMS accepted the pack, reported state-of-charge correctly, and did not trigger low-voltage cutoff prematurely under sustained 4K recording load.
• First-cycle BMS initialisation: On first install, perform one full charge cycle through the camera body or OEM charger before heavy shooting. Some Canon Cinema bodies require an in-body charge cycle to calibrate the battery-remaining display to the new cell's discharge curve.

Canon Cinema EOS battery percentage reading stuck or inaccurate after install

Canon Cinema EOS bodies map their battery percentage indicator to a specific discharge curve stored in the camera's BMS. A new third-party cell has a slightly different discharge profile, so the camera can report a flat or frozen percentage until it completes one full charge-discharge reference cycle. The fix is straightforward: charge the pack to full via the camera body, run it down under normal shooting load, then charge again fully. After that cycle, the indicator tracks the cell accurately.

Shot count dropping sharply when autofocus, IBIS, or EVF are active simultaneously

Rated capacity reflects a baseline draw figure — it does not account for the combined current demand of continuous phase-detect AF, in-body stabilisation, the electronic viewfinder backlight, and active cooling. On Cinema EOS bodies under 4K recording with all systems running, combined draw can exceed the spec assumption by a significant margin. This is a draw problem, not a cell fault. Reduce EVF brightness, switch AF to one-shot where possible, and monitor the camera's remaining charge indicator rather than projecting from spec alone.
