Nokia V8130 Ni-MH Replacement Battery 6V 4200mAh

Nokia V8130 / V8230 / V8300 / V8320 — 6V Ni-MH Replacement Battery

This is a 6V, 4200mAh Ni-MH replacement battery for Nokia digital cameras including the V8130, V8230, V8300, and V8320. It fits the original battery compartment and connects to the same terminals as the factory cell. Capacity is rated at 25.2Wh from the product specification.

• V8130 / V8230 / V8300 / V8320 platform fit: These four models share the same battery bay dimensions, terminal layout, and voltage rail. Swapping cells across these bodies works because the BMS on each reads the same 6V nominal and uses the same connector pinout.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on camera-class load profiles. The BMS accepted the cell without flagging an incompatible battery warning, and charge termination triggered correctly at full capacity.
• First-cycle initialisation on Nokia camera bodies: Run the first full charge from inside the camera body or the OEM charger before shooting. Some Nokia camera BMS firmware maps the battery-level display to a discharge curve it only calibrates after one complete in-body charge cycle — skipping this step causes the indicator to read inaccurately from the start.

Flash recycling slowdown on a fresh Ni-MH cell

Ni-MH cells deliver lower peak current than lithium cells at the same nominal voltage. The flash capacitor recharges by pulling a sharp current spike after each shot. If the cell's internal resistance is slightly elevated — common in the first few cycles before the cell reaches full capacity — that spike causes a brief voltage sag. The camera interprets the sag as low power and delays the next flash-ready signal. After three to five full charge-discharge cycles, internal resistance drops and recycling speed normalises.

Battery percentage jumping erratically on the V8130 display

The V8130 battery indicator maps display segments to fixed voltage thresholds tuned to the original cell's discharge curve. A new Ni-MH replacement has a flatter discharge curve, so the camera may read a large percentage drop suddenly near the end of the charge, or show full bars longer than expected. This is a display calibration issue, not a cell fault. Perform two full charge-discharge cycles and the BMS will track the new cell's curve more accurately — check the indicator stabilises across a full discharge before assuming the cell is defective.
