Canon NB-1L IXUS 200a Replacement Battery 3.7V 830mAh

Canon Digital IXUS 200a / IXUS 300 Series — 3.7V Li-ion Replacement Battery (NB-1L)

This is a 3.7V, 830mAh Li-ion replacement for the Canon NB-1L and NB-1LH cells. It fits the Digital IXUS 200a, IXUS 300, IXUS 300a, IXUS 320, and 28 additional IXUS and PowerShot models that share the same battery bay and connector. Capacity matches the original Canon spec at 830mAh (3.07Wh).

• IXUS 200a / 300 series compatibility: Canon grouped these compact bodies around the same 3.7V single-cell platform, using an identical physical footprint and contact arrangement. The NB-1L and NB-1LH draw from the same voltage rail, so one cell covers the full list of affected models without any adapter or wiring change.
• Bench tested on actual hardware: We cycled this cell through a Canon IXUS body, monitoring BMS handshake, charge acceptance, and discharge curve under simulated shooting load — burst capture, flash recycling, and LCD-on sustained use. The BMS accepted the cell and reported charge state without error flags across all test cycles.
• First charge cycle on the IXUS body: Before your first shoot, run one complete charge cycle through the Canon charger or inside the camera body itself. Some IXUS BMS builds calibrate the battery-remaining display against the cell's discharge curve only after completing a charge from within the body — skipping this step can cause inaccurate level readings early on.

Flash recycling lag on the IXUS 300 series with a new replacement cell

The IXUS flash capacitor pulls a sharp current spike each time it recharges between shots. On a new or deeply discharged cell, internal resistance is slightly elevated until the cell is properly cycled. This causes the capacitor recharge to take fractionally longer, which the camera shows as a delayed ready indicator. Run two or three full charge-discharge cycles and the internal resistance drops to normal operating range, restoring typical flash recycling speed.

Battery percentage jumping or reading incorrectly after fitting the replacement

The IXUS battery indicator maps voltage thresholds to percentage steps based on the discharge curve it learned from the previous cell. A new NB-1L cell has a slightly different starting voltage profile until it is calibrated. The display may show full, then jump to one bar, or report empty while the cell still has charge. Complete one full charge via the Canon charger, then discharge through normal use — the indicator stabilises once the body has mapped the new cell's curve. After that first cycle, readings track accurately.
