Ingenico IWE280 Replacement Battery 3.7V 3400mAh 295006044

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

This is a 3.7V 3400mAh Li-ion replacement battery for the Ingenico IWE280 and IWL220 series portable payment terminals. It fits the iWL220 GPRS, iWL250, and over a dozen related models sharing the same battery bay and connector. Capacity is 12.58Wh, matching the original cell specification.

• IWL220 and IWE280 platform compatibility: These terminals share a common battery bay geometry, connector pinout, and BMS handshake protocol across the iWL220, iWL220 GPRS, iWL250, and IWE280 variants — the same cell fits all of them without modification.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the IWL220 platform. The BMS accepted the cell handshake on first boot, charge IC entered top-off mode correctly, and the terminal reported state-of-charge without prompting a service flag.
• First deployment cycle: After installing this battery, run one complete transaction cycle — including a receipt print — before putting the terminal into live service. The terminal maps battery capacity during normal operation and needs at least one full power cycle to calibrate the charge indicator accurately.

Receipt printer causing unexpected battery drain on IWL220

The thermal printer in the iWL220 series draws a sharp current spike — typically 1.5A or more — at the moment it fires the print head. On a degraded original battery, that spike causes the BMS to register an overcurrent event and throttle output. A new cell with full capacity handles the combined display, wireless, and printer load without triggering that threshold. If drain still seems high after swap, check that the terminal is not sitting in continuous polling mode on a weak GPRS signal, which adds a persistent background draw.

Terminal stuck on boot screen after new battery installed

The IWL220 and IWE280 run a PCI security boot sequence that requires stable voltage throughout. If the BMS handshake has not completed its first initialisation cycle, the terminal may stall on the boot screen or restart before reaching the home menu. This is not a faulty battery — it is the BMS and charge IC negotiating on a fresh cell. Connect the terminal to its dock or charger, let it reach a full charge from the new cell, then power cycle it. After one complete charge cycle the boot sequence completes normally.
