About this replacement
Ingenico Link 2500 — 3.7V Li-Polymer Replacement Battery (296203895AB)
This is a 3.7V, 1200mAh Li-Polymer battery for the Ingenico Link 2500 portable payment terminal. It replaces OEM part numbers 296203895AB and P0750-LF. The Link 2500 is a mobile POS device, and this battery keeps it running through daily card transactions in the field.
- Link 2500 fit: The Link 2500 uses a compact Li-Polymer cell at 3.7V with a specific connector and BMS handshake. This battery matches that voltage rail, connector pinout, and BMS communication protocol so the terminal recognises it correctly on first boot.
- Bench tested on actual hardware: We ran this battery through a full boot cycle on the Link 2500 and confirmed the BMS handshake completed without fault codes. The charge IC accepted the cell and the terminal reported battery status correctly in the settings menu.
- Post-installation calibration: After fitting, complete one full transaction cycle before deploying in a live environment. The Link 2500 maps battery capacity during normal operation and needs at least one complete power cycle to display the charge indicator accurately.
Terminal rebooting mid-transaction after battery swap
The Link 2500 draws a short current spike when the receipt printer fires. On a new cell that hasn't completed a full charge cycle, the BMS can read this spike as an overcurrent event and trip the protection circuit. This cuts power momentarily and forces a reboot mid-sale. The fix is straightforward — charge the battery to 100% and complete one full transaction cycle before taking the terminal into production use.
Link 2500 not powering on after sitting unused
Li-Polymer cells self-discharge slowly during storage. If the terminal has been sitting in a drawer for several weeks, the cell voltage may have dropped below the BMS recovery threshold — typically around 2.5V. The terminal will not power on because the BMS locks out the output to protect the cell. Connect to the charger and leave it for at least 30–45 minutes before attempting to power on; most BMS circuits enter a slow pre-charge mode that recovers the cell once voltage crosses 3.0V.
