About this replacement
VeriFone Nurit 2085U / 2090 — 7.2V Ni-MH Replacement Battery (BAT00023)
This is a 7.2V, 1500mAh Ni-MH replacement battery for the VeriFone Nurit 2085U and Nurit 2090 wireless payment terminals. It replaces OEM part numbers BAT00023 and 150AAM6BMX. The Nurit 2085U is a portable POS terminal used by merchants in the field for credit card transactions.
- Nurit 2085U and 2090 compatibility: Both terminals share the same battery bay dimensions, connector pinout, and BMS handshake protocol, so a single cell covers both units without modification.
- Bench tested on actual hardware: We ran this battery through the Nurit 2085U boot sequence and a full transaction cycle. The BMS accepted the handshake on first boot and the charge IC moved out of trickle mode after one complete cycle.
- First deployment tip for POS terminals: After installation, complete one full transaction cycle before taking the terminal into a live environment. The Nurit maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.
Terminal rebooting mid-transaction after a battery swap
The Nurit 2085U draws a combined load from the wireless radio, receipt printer motor, and backlit display during a transaction. On a new Ni-MH cell, the BMS protection threshold is tighter until the cell completes its first few charge-discharge cycles. A printer motor start spike can momentarily push current draw past the BMS trip point, cutting power mid-transaction. Run the terminal through three to five complete transaction cycles off-peak to condition the cell and allow the BMS to settle at its normal operating threshold.
Terminal will not power on after sitting unused in a drawer
Ni-MH cells self-discharge at roughly 1–3% per day. A Nurit 2085U left in storage for several weeks can arrive with a cell voltage too low for the BMS to permit startup — the terminal shows nothing when the power button is pressed. Connect the terminal to the dock charger and leave it for a full charge cycle without interrupting it. If voltage recovers above the BMS recovery threshold (approximately 5.4V for this 6-cell pack), the terminal will boot normally on the next power attempt.
