Revue DC 10.1 Compatible Battery 3.7V 1250mAh 02491-0028-01

Revue DC 10.1 / DC 80 / DC 80 SZ — 3.7V Li-ion Replacement Battery (02491-0028-01)

This is a 3.7V, 1250mAh Li-ion cell built to the OEM part number 02491-0028-01. It fits the Revue DC 10.1, DC 100, DC 80, and DC 80 SZ compact digital cameras. Dimensions are 41.95 × 36.05 × 9.80mm — matching the original battery bay exactly.

• DC 10.1 / DC 80 series compatibility: These models share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol. One cell fits the full range without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a DC 10.1 body. The BMS accepted the cell without fault codes. Voltage held steady across the mid-range discharge curve under continuous shooting load.
• First-cycle charge procedure: On the DC 10.1 and DC 80 series, run the first full charge inside the camera body using the OEM cable — not a standalone charger. Some Revue bodies only calibrate the battery-remaining indicator after completing a charge cycle through the internal charging circuit.

The DC 10.1 maps its battery indicator to a fixed voltage-threshold table stored in firmware. A new cell with a slightly different discharge curve can read as empty even when it holds useful charge. This happens most often on first use, before the camera body has logged a full charge-discharge cycle on the new cell. Run one complete charge cycle through the camera body, then discharge fully in normal shooting. After that cycle, the indicator should track the actual charge state accurately.

Flash not recycling fully between shots

The built-in flash on the DC 10.1 draws a short high-current burst to recharge its capacitor after each shot. If the cell voltage sags under that burst, the capacitor doesn't reach full charge before the next frame. You'll see the flash indicator light stay on longer than normal, or output visibly weaker than the first shot. Check the cell resting voltage — it should read at or above 3.9V after a full charge. If it drops below 3.7V immediately under flash load, the cell needs replacing or has not completed its first calibration cycle.
