Ingenico IWE280 POS Terminal Replacement Battery 3.7V 2200mAh

Ingenico IWL220 / IWE280 Series — 3.7V Li-ion Replacement Battery (295006044)

This is a 3.7V Li-ion 2200mAh replacement battery for the Ingenico IWE280, IWL220, iWL220 GPRS, and iWL250 portable payment terminals. It replaces OEM part numbers 295006044, 296110884, F26401964, F26402274, F26402298, L01J44007, and L01J44006. The cell fits the original battery bay and connects to the same BMS contact points as the factory unit.

• IWL220 and IWE280 shared battery platform: These terminals run the same 3.7V single-cell architecture with a matched connector footprint and BMS handshake protocol. One battery part number covers the full range because the charge IC and cutoff thresholds are identical across the series.
• Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on the IWL220 platform. The BMS accepted the handshake without errors, charge IC entered top-off mode at 4.15V, and the low-voltage cutoff tripped correctly at 3.0V under load.
• First deployment cycle on payment terminals: After installing this battery, complete one full transaction cycle before using the terminal in a live environment. The terminal maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.

Terminal not completing PCI boot sequence after battery swap

The IWL220 and IWE280 run a PCI security boot check on every power-up. If the BMS handshake has not yet been accepted by the charge IC, the terminal can stall or loop at the boot screen before reaching the transaction interface. This happens because the charge IC needs to confirm cell voltage is within a valid operating window before releasing the system to full boot. Charge the terminal to at least 3.6V before the first power-on, then allow one full boot sequence to complete.

Terminal rebooting mid-transaction during receipt printing

The receipt printer motor draws a sharp current spike — often 800mA or more — on top of the wireless radio and display load. On a degraded or newly installed battery, this combined draw can trip the BMS overcurrent threshold and force an unexpected reboot. This is not a terminal fault. The fix is to ensure the battery is fully charged before field use and to complete the initial capacity-mapping cycle described above. If reboots continue on a fully charged cell, check that the battery connector is fully seated — a partial connection raises contact resistance and amplifies voltage sag under load.
