About this replacement
Toshiba Gigashot V10 — 3.7V Li-ion Replacement Battery (MEHBT4)
This is a 3.7V, 1230mAh Li-ion cell built to the MEHBT4 specification for the Toshiba Gigashot V10 compact video camera. It powers recording, playback, and menu functions at the same voltage rail as the original. Capacity is 4.55Wh — identical to factory spec.
- Gigashot V10 fitment: The V10 uses a compact single-cell Li-ion pack at 3.7V nominal. The MEHBT4 form factor — 42.16 × 36.52 × 10.68mm — seats flush in the battery compartment with correct contact alignment. No adapter or modification needed.
- Bench tested on actual hardware: We cycled this cell through the V10's charge and discharge sequence. The BMS accepted the cell on the first in-camera charge cycle, with the battery indicator reading correctly after one full charge from empty.
- First-use charge cycle on the Gigashot V10: Insert the cell and charge fully in the camera body or OEM charger before your first recording session. The V10's battery-remaining display calibrates its threshold mapping during this initial cycle — skipping it can cause the indicator to drop early or read inaccurately across the charge curve.
Why the Gigashot V10 shows a dead battery indicator on a partially charged replacement cell
The V10 maps its battery-remaining display to voltage thresholds set during the BMS initialisation cycle. A new cell that hasn't completed one full charge-to-empty cycle in the camera body can present a discharge curve the BMS doesn't recognise. The camera interprets mid-range voltage readings as critically low and throws the dead battery warning. Running one complete charge cycle from below 3.0V up to 4.2V inside the camera resets this mapping and the indicator stabilises.
Battery percentage jumping erratically on the V10 display
If the remaining-charge percentage skips — say, 80% to 40% in seconds without recording — the voltage-to-percentage lookup table in the V10's BMS is misreading the new cell's discharge curve. This is common after swapping cells without a calibration cycle. The fix is straightforward: discharge the cell fully until the camera shuts down, then charge uninterrupted to 4.2V in a single session. After that cycle, the percentage readout tracks the actual state of charge accurately.
