SVP BLI-248 Nikon Coolpix DV-8300 Compatible Battery 3.7V 750mAh

SVP DV-8300 / US-P — 3.7V Li-ion Replacement Battery (BLI-248)

This is a 3.7V 750mAh Li-ion cell built to the BLI-248 spec, replacing the original battery in the SVP DV-8300 and US-P digital cameras. It fits the original battery compartment and connects to the same charging circuit. Capacity is 2.78Wh — matching the stock cell.

• DV-8300 and US-P compatibility: Both models share the same battery bay dimensions and charge management circuit, so a single BLI-248-spec cell covers both. The connector orientation and BMS handshake profile are identical across the two platforms.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on a DV-8300 body. The BMS accepted the charge curve without fault flags, and the protection circuit triggered correctly at the low-voltage cutoff threshold.
• Fuel gauge reset on the DV-8300: After fitting this cell, run one complete discharge-to-charge cycle before shooting. The camera's fuel gauge IC was calibrated to the old cell's discharge curve. One full cycle lets it recalibrate against this cell so the battery indicator reads accurately.

Why the DV-8300 shows wrong battery level after a cell swap

The DV-8300 tracks charge state using a coulomb counter tied to the original cell's discharge profile. A new cell has a slightly different internal resistance, which shifts the voltage curve the camera expects. Until the gauge IC recalibrates, the percentage display lags behind actual charge state. One full discharge and recharge cycle resets the reference point and brings the indicator back in line.

Camera won't power on after the replacement cell sat in storage

Li-ion cells shipped or stored at partial charge can drop below 2.5V per cell during long periods without use. When that happens, the BMS locks the cell out to prevent damage from deep-discharge charging. Plug the camera into its charger and leave it connected for at least 15–20 minutes without attempting to power on — the charge IC needs to push a trickle current through before the BMS releases the lockout. If the camera still won't respond after 30 minutes on charge, check that the charger is delivering at least 4.2V at the connector.
