About this replacement
VeriFone e280s / e280s V2 — 3.85V Li-ion Replacement Battery (BPK457-001)
This 3.85V 3000mAh Li-ion cell replaces the original battery in the VeriFone e280s and e280s V2 mobile payment terminals. It matches the OEM voltage rail, connector, and BMS communication protocol the terminal expects. Rated at 11.55Wh and built to the same physical footprint at 81.30 × 52.60 × 5.70mm.
- e280s and e280s V2 compatibility: Both variants run the same 3.85V power rail and share the BPK457-001 connector and BMS handshake. The same cell fits both — no hardware difference in how they draw or communicate with the battery pack.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on the e280s platform. The BMS accepted the handshake cleanly on first boot, charge IC reached top-off without faults, and the terminal reported state-of-charge correctly after one full power cycle.
- First deployment tip: After fitting the battery, complete one full transaction cycle — including a receipt print — before deploying 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 accurately.
Payment terminal rebooting mid-transaction after battery swap
The e280s draws a combined load from the display, wireless radio, and receipt printer simultaneously during a transaction. On a new or cold cell, that combined current spike can trigger the BMS overcurrent protection before the pack has completed its first full calibration cycle. The BMS interprets the surge as a fault and cuts output, causing the terminal to restart. Run at least one complete transaction cycle — print included — before live deployment, and the BMS will map the load profile correctly from that point forward.
Terminal not completing PCI boot sequence on a freshly installed battery
The e280s runs a PCI-compliant security boot that checks battery state before completing initialisation. If the BMS handshake hasn't been accepted yet, or the cell voltage reads below the terminal's minimum threshold from storage discharge, the boot sequence stalls or loops. Connect the terminal to a charger and allow it to reach at least 3.7V before attempting to power on. One full charge cycle resolves the handshake and lets the PCI sequence complete normally.
