Valor VL110 Payment Terminal Replacement Battery 3.7V 2600mAh

Valor VL110 — 3.7V Li-ion Replacement Battery (V3M2)

This is a 3.7V, 2600mAh Li-ion replacement battery for the Valor VL110 payment terminal. It matches the OEM part number V3M2 and restores full operating capacity to terminals where the original cell has degraded. Fits the VL110 directly — no modification needed.

• VL110 platform fit: The VL110 uses a single-cell Li-ion pack at 3.7V nominal. The V3M2 cell dimensions (67.05 × 21.10 × 18.80mm) and connector match the OEM bay exactly. The BMS on the VL110 communicates over a standard charge line — this cell's protection circuit responds to that handshake without triggering a fault code.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on a VL110 unit. The BMS accepted the cell on first boot, the charge indicator responded correctly, and no overcurrent trips occurred during receipt print cycles or wireless transaction loads.
• Post-install transaction cycle: After fitting this battery, run one complete transaction — power on, process a sale, print a receipt — before putting the terminal into live service. The VL110 maps battery capacity during normal operation. One full cycle lets the charge indicator calibrate accurately rather than displaying an estimated value.

Terminal rebooting mid-transaction after battery swap

The VL110's receipt printer draws a short current spike when it fires the print head — typically higher than the steady wireless or display draw. On a new or cold cell, the BMS may read that spike as an overcurrent event and cut power to protect the pack. This causes an unexpected reboot that looks like a software fault but is electrical. Let the terminal complete two or three idle charge-discharge cycles before high-volume use. If the reboots continue, check that the battery contacts are clean and the cell is seated firmly — a loose connection amplifies voltage sag during the print spike.

Terminal not powering on after sitting unused in a drawer

Li-ion cells self-discharge at roughly 1–2% per month. A VL110 left unused for several months can drop below 3.0V, which is the point where most BMS circuits lock the cell and refuse to pass current as a deep-discharge protection measure. Plug the terminal into its charger and leave it connected for at least 30–40 minutes before pressing the power button — the charger's trickle stage needs time to bring the cell back above the BMS recovery threshold. If the terminal still won't respond, check that the charge LED is active; no LED means the charger itself is not delivering current to the port.
