Rayovac RV-DC8100 Replacement Battery 7.4V 2600mAh

Rayovac RV-DC8100 — 7.4V Li-ion Replacement Battery

This is a 7.4V, 2600mAh (19.24Wh) Li-ion replacement battery for the Rayovac RV-DC8100 digital camera. It fits imaging equipment used in field documentation, site surveying, and inspection workflows. Voltage and cell count match the original pack exactly.

• RV-DC8100 platform fit: The RV-DC8100 uses a 7.4V two-cell Li-ion configuration with a specific connector layout and BMS handshake. This replacement matches that cell count, voltage rail, and connector footprint so the camera's charge controller accepts the pack without fault codes.
• Bench tested on actual hardware: We cycled this pack through camera power-on, active image capture, and USB data transfer simultaneously. The BMS held voltage above the camera's 6.8V cutoff threshold under combined draw without tripping into protection mode.
• First-use calibration on the RV-DC8100: After installing this pack, run the camera through a full charge cycle before heading into the field. The RV-DC8100 maps battery state during its first full charge-to-discharge cycle — skipping this causes the battery indicator to show premature low warnings during the first documentation session.

RV-DC8100 shutting down mid-session during USB data transfer

The RV-DC8100 pulls current from the battery for both active imaging and USB bus power simultaneously during a PC transfer. A degraded or partially discharged original pack often can't sustain the combined draw, and the BMS trips the cutoff. This replacement's 2600mAh capacity gives the pack more headroom to handle that combined load without a voltage sag event. If the camera still cuts out, check that the pack is above 7.2V before starting a transfer session.

Battery indicator jumping erratically on the RV-DC8100 after installing a new pack

The RV-DC8100's charge indicator is calibrated to the voltage curve of the cell it first mapped. A new cell has a slightly different open-circuit voltage at each state of charge, so the display reads inconsistently until the camera recalibrates. Run one full charge from flat to 100% without interrupting the cycle. After that single conditioning cycle, the indicator tracks correctly against the new cell's voltage curve.
