VeriFone E285 POS Terminal Replacement Battery 3.8V 1750mAh

VeriFone E285 — 3.8V Li-ion Replacement Battery (BPK087-600)

This is a 3.8V, 1750mAh Li-ion battery for the VeriFone E285 and IPAY E285 payment terminals. It replaces OEM part numbers BPK087-600, BPK087-600-01-A, BPK087-600-01-B, and BPK087-600-01-C. If your terminal is shutting down mid-transaction or refusing to hold a charge, this is the direct swap.

• E285 and IPAY E285 fit: Both variants run the same 3.8V battery bay, BMS connector pinout, and charge IC handshake. The -01-A, -01-B, and -01-C suffixes are VeriFone hardware revision codes — the cell spec and connector are unchanged across all three.
• Bench tested on actual hardware: We cycled this battery through charge-discharge on an E285 unit and confirmed the BMS accepted the cell without fault codes. The charge IC completed top-off mode and the terminal read battery status correctly across multiple power cycles.
• First deployment tip for the E285: After installing this battery, run one complete transaction — tap or swipe through to receipt — before deploying in a live checkout environment. The terminal maps cell capacity during normal operation and needs at least one full power cycle to calibrate the charge indicator correctly.

Why the E285 reboots mid-transaction after a battery swap

The E285 draws a combined load from its display, wireless radio, and receipt printer simultaneously during a transaction. On a new or partially discharged cell, that combined spike can push current demand past the BMS overcurrent threshold, triggering a protective cutoff that looks like a random reboot. The BMS on this cell is set to the E285's rated draw envelope. If reboots continue after the first few transactions, check that the terminal firmware is current — older builds have an aggressive low-voltage cutoff that trips too early on cells below 3.6V.

Terminal stuck at 99% charge and not dropping — what that means

A new Li-ion cell arrives at a partial state of charge for transport safety. When first connected to a charger, the E285's charge IC enters top-off mode and holds the display at 99% while it brings the cell to full capacity at a low trickle rate. This is normal behaviour — it is not a fault with the battery or the terminal. The indicator will move to 100% and then begin reporting normally once the charge IC exits top-off mode, typically after the first complete charge cycle.
