Canon NB-6L Digital IXUS 200 IS Replacement Battery 3.7V 850mAh

Canon IXUS 200 IS / IXUS 210 — 3.7V Li-ion Replacement Battery (NB-6L)

This is a 3.7V, 850mAh (3.15Wh) lithium-ion battery for the Canon Digital IXUS 200 IS and the broader NB-6L camera family. It fits the IXUS 95 IS, IXUS 105, IXUS 210, and over 36 additional Canon compact models that share the same battery bay and connector. Slot it in using the same orientation as the original cell.

• IXUS and PowerShot NB-6L platform: These Canon compacts share a standardised 3.7V battery bay, a common connector pinout, and a BMS handshake that authenticates the cell on first power-up. The NB-6L and NB-6LH both map to this same socket and communication protocol, so one cell covers the full model range.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on NB-6L compatible bodies. The BMS accepted the cell without fault codes, voltage held within spec across the discharge curve, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• First-use charge cycle on IXUS bodies: On first install, charge the battery fully inside the camera body or OEM charger before shooting. Some Canon compact BMS systems need one complete in-body charge cycle to calibrate the battery-remaining indicator to the new cell's discharge curve — skipping this step can cause the indicator to read inaccurately from the start.

Why the IXUS 200 IS shows a dead battery icon on a partially charged replacement cell

Canon's compact BMS maps battery percentage against a voltage-discharge profile calibrated to the original NB-6L cell. A new third-party cell has a slightly different discharge curve, so the camera's voltage thresholds don't line up correctly on the first few cycles. The camera reads a mid-charge voltage as critically low and throws the dead battery icon even when the cell still has capacity. Run one full charge-to-discharge cycle through the camera body and the indicator typically re-aligns to the actual state of charge.

Battery percentage jumping erratically during a shoot

This happens when the camera's voltage-threshold indicator maps its percentage steps to a discharge curve the new cell doesn't perfectly match. The indicator can jump from 60% to 10% in a few frames, then recover — not because the cell is failing, but because the BMS is sampling a voltage dip during flash recharge or continuous AF and mapping it to the wrong percentage band. After two or three full charge cycles, the BMS refines its mapping and the readout stabilises. If it persists beyond three cycles, check that the battery contacts in the bay are clean and making firm contact — dirty contacts cause momentary voltage drops that the BMS misreads as rapid depletion.
