ALBA SL1031 Compatible Battery 3.7V 660mAh Li-ion

ALBA SL1031 / SL1231 / SL1430 — 3.7V Li-ion Replacement Battery

This 3.7V 660mAh Li-ion cell replaces the original battery in the ALBA SL1031, SL1231, and SL1430 compact digital cameras. It restores power to cameras where the original cell no longer holds a charge or has failed entirely. Voltage and capacity match the original spec to keep the camera's exposure, flash, and image-write functions within normal operating parameters.

• SL1031, SL1231, SL1430 compatibility: These three ALBA models share the same battery bay dimensions, contact layout, and 3.7V power rail. The same 40.00 × 31.10 × 5.90mm cell footprint fits all three without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles monitoring BMS communication, flash capacitor recharge current, and cutoff behaviour at low state of charge. The cell accepted charge via both OEM charger and in-body charging without tripping protection circuits.
• First-install charge cycle: Insert the cell into the camera body and run a full charge cycle through the camera before shooting. Some compact camera BMS systems only calibrate the battery-remaining indicator after one complete in-body charge cycle — skipping this step can cause the indicator to read inaccurately from the first use.

Battery percentage jumping or reading 100% then dropping suddenly on the ALBA SL1031

The SL1031's fuel gauge maps voltage thresholds from the original cell's discharge curve. A new replacement cell has a slightly different discharge curve at the mid-range, which causes the indicator to jump between values rather than step down smoothly. This is a calibration issue, not a cell fault. Run two full charge and discharge cycles through the camera body and the indicator will remap to the new cell's curve, giving stable percentage readings.

Camera body warming up and draining the new cell faster than expected during video recording

During video recording, the SL1031 draws simultaneously from the image sensor, the image processor, and the write buffer — all at once, sustained. This combined draw is significantly higher than the load during still photography. At 660mAh the cell is rated at 2.44Wh, which is the same as the original spec, so the behaviour is normal for extended video use rather than a fault with the replacement cell. If the camera shuts down during video, check that the cell is reading above 3.5V before the session starts — anything below that threshold puts the camera at risk of mid-recording cutoff.
