Sanyo DB-L10 Xact DSC-J1 Replacement Battery 3.7V 1090mAh

Sanyo Xact DSC-J1 / Xacti Series — 3.7V Li-ion Replacement Battery (DB-L10)

This 3.7V, 1090mAh lithium-ion cell replaces the OEM DB-L10 and DB-L10A batteries across Sanyo's Xact and Xacti compact camera lineup. It fits the DSC-J1, DSC-J2, DSC-AZ3, DSC-MZ3, and nine additional Xacti models. Dimensions are 46.00 × 31.85 × 9.85mm — same footprint as the original cell.

• Xact / Xacti platform fit: These cameras share the same DB-L10 battery bay, connector pinout, and 3.7V nominal rail across the compact point-and-shoot range. One cell covers the full model group without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on Xacti-class bodies. The BMS accepted the cell cleanly, protection circuitry tripped correctly at low-voltage cutoff, and charge termination behaved as expected under OEM charger conditions.
• First-install charge cycle on Xacti bodies: Insert the new cell and run a full charge inside the camera body or OEM charger before your first shoot. Some Xacti BMS firmware maps its battery-remaining display to a discharge curve it calibrates on that first cycle — skipping it can cause the indicator to read inaccurately from the start.

Battery percentage jumping erratically on the Xacti display

Sanyo's Xacti indicator maps remaining charge to a voltage-threshold table calibrated against the original cell's discharge curve. A fresh replacement cell can have a slightly different curve shape at mid-charge, which causes the indicator to skip between readings rather than step down smoothly. This is a firmware mapping issue, not a fault with the cell. Running two full charge-discharge cycles through the camera body typically tightens the indicator back to normal behaviour.

If the camera cuts to a dead-battery screen shortly after a new cell is inserted, the BMS has likely read an open-circuit voltage below its acceptance threshold — common when a replacement cell arrives partially discharged from storage. Place the cell in the OEM charger first rather than charging via the camera body. Once it reaches at least 3.9V and the charger confirms a full cycle, re-insert it. The camera should clear the error and display normal battery status.
