Mevo A7310 Compatible Battery 3.7V 950mAh Li-ion

Mevo A7310 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 950mAh (3.52Wh) lithium-ion battery for the Mevo A7310 compact camera. It slots into the A7310 body and powers the imaging system, including recording and photo capture. When the original cell degrades and shot count drops noticeably, this cell restores capacity to spec.

• A7310 fit: The A7310 uses a compact single-cell Li-ion pack at 3.7V nominal. This replacement matches that voltage rail and physical footprint, so the battery door closes and the BMS communication pins align correctly.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on camera-class test equipment. The BMS held the charge termination voltage correctly and protection circuitry tripped at expected low-voltage cutoff without locking the pack.
• First-install charge cycle on the A7310: Run the new cell through one complete charge inside the A7310 body or an OEM-compatible charger before shooting. Some compact camera BMS systems only map the battery-remaining display accurately after reading a full charge curve from a new cell on first install.

Why the A7310 displays a dead-battery icon on a partially charged new cell

The A7310 BMS maps battery percentage against a stored voltage-threshold table built around the original cell's discharge curve. A new cell fresh from storage often sits at a mid-state voltage that falls outside what the camera expects at that charge level. The camera reads this as critically low and locks out operation. Charging the cell fully inside the camera body once resets this mapping and the indicator reads correctly from that point on.

Battery percentage jumping erratically during a shoot

This happens when the camera's voltage-to-percentage lookup table doesn't match the discharge curve of the replacement cell. As the cell voltage drops under load — during continuous recording or rapid shot bursts — the camera samples voltage at moments of sag and maps it to the wrong percentage step. The result is the indicator skipping several points down, then recovering when load drops. After one full discharge and recharge cycle in the A7310 body, the BMS recalibrates and the percentage readout stabilises — confirm by letting the cell drop to the low-battery cutoff at approximately 3.0V before recharging.
