Ingenico iWE280 Payment Terminal Replacement Battery 3.7V 2600mAh

Ingenico iWL220 / iWE280 Series — 3.7V Li-ion Replacement Battery (295006044)

This 3.7V 2600mAh Li-ion battery replaces the OEM cell in the Ingenico iWE280, iWL220, iWL220 GPRS, and iWL250 payment terminals. It matches the original form factor and connector, so it fits without modification. Capacity figure is sourced from the product data — 9.62Wh.

• iWL220 and iWE280 platform fit: These terminals share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers the full group because Ingenico standardised the battery interface across this portable terminal generation.
• Bench tested on actual hardware: We cycled this cell through a full boot, transaction sequence, and receipt print on the iWL220. The BMS accepted the handshake on first power-up and voltage held steady through the combined wireless and printer draw without a trip event.
• First deployment prep for POS terminals: After fitting the battery, complete one full transaction cycle before deploying the terminal on a live counter. The charge indicator in Ingenico terminals maps capacity during normal operation, not during a static charge hold — one complete power cycle sets the gauge correctly.

Terminal rebooting mid-transaction after battery swap

The iWL220 and iWE280 pull a short current spike when the receipt printer fires. On a new cell that hasn't completed a full charge-discharge cycle, the BMS can read that spike as an overcurrent event and cut power. This causes the terminal to reboot mid-sale — appearing as a software fault when it's actually a BMS protection trip. Run the terminal through two or three complete transaction cycles after the first charge and the BMS threshold normalises to the printer load. If resets continue, check that the battery contacts are clean and fully seated.

Terminal won't power on after sitting unused in a drawer

Li-ion cells self-discharge at roughly 2–3% per month. A terminal left uncharged for six months or more can have a cell voltage below 2.5V — the point where most BMS circuits lock out to prevent damage. The terminal shows nothing on screen and won't respond to the power button. Connect the terminal to its original charger and leave it for 30–40 minutes before attempting to power on; most Ingenico chargers include a trickle-charge stage that brings the cell back above the 2.8V recovery threshold before normal charging begins.
