VeriFone e280 POS Terminal Replacement Battery BPK087-700 3.85V

VeriFone e280 — 3.85V Li-Polymer Replacement Battery (BPK087-700)

This 3.85V, 1900mAh Li-Polymer battery replaces the original BPK087-700 / BPK087-700-01-A in the VeriFone e280 payment terminal. It fits the e280 and M087-602-11-WWA configurations. Swap it in when the original cell no longer holds charge through a normal transaction shift.

• e280 and M087-602-11-WWA compatibility: Both variants run the same 3.85V power rail and use the same connector footprint and BMS handshake protocol, so one cell covers both. No firmware or hardware difference affects fitment.
• Bench tested on actual hardware: We cycled this cell through the e280 boot sequence and ran it through print-and-tap transaction loops. The BMS accepted the handshake without fault codes, and the charge IC reached full-cell voltage without triggering overcurrent protection on the printer motor draw.
• First-deployment cycle on the e280: After fitting this battery, complete at least one full transaction cycle — card tap, receipt print, and idle screen — before putting the terminal into a live shift. The e280 maps battery capacity during normal operation and needs that first complete power cycle to register the charge indicator accurately on the management screen.

Why the e280 reboots mid-transaction after a battery swap

The e280's receipt printer pulls a short current spike — typically 800mA to over 1A — at the moment the print head fires. On a new cell that has not yet completed a full charge cycle, the BMS can read that spike as an overcurrent event and cut power to protect the cell. The terminal then restarts, which looks like a software crash but is actually a protection trip. Run the terminal through a complete charge-to-full cycle first, then test with a print job before going live. After the BMS has logged one full cycle, the trip threshold adjusts and the mid-transaction reboot stops.

Terminal stuck on the boot screen after sitting unused in a drawer

Li-Polymer cells self-discharge at roughly 2–3% per month. If an e280 sits unused for several months, the cell can drop below the 3.0V recovery threshold, at which point the BMS locks the discharge path and the terminal will not boot — it may show nothing or freeze on the VeriFone logo. Connect the terminal to its original charger and leave it for 30–60 minutes without pressing any buttons; the charger applies a low-current pre-charge to bring the cell back above the BMS recovery threshold. Once the cell reaches approximately 3.2V, the BMS re-enables the discharge path and the terminal boots normally.
