About this replacement
VeriFone Nurit 3020 / 8320 Series — 7.2V Ni-MH Replacement Battery (BAT0017-B)
This is a 7.2V, 700mAh Ni-MH replacement battery for the VeriFone Nurit 3020, Nurit 3020U, Nurit 8320, and Nurit 8320U payment terminals. It replaces OEM part numbers BAT0017-B and 70AAAH6BMXZ. These terminals use this battery during mobile and countertop payment operations when mains power is unavailable.
- Nurit 3020 and 8320 platform fit: Both the 3020 and 8320 families share the same battery bay dimensions, connector pinout, and charge management circuit. One replacement covers all four model variants without modification.
- Bench tested on actual hardware: We cycled this cell through the Nurit charge circuit and confirmed the BMS accepted the handshake correctly. The terminal completed its PCI boot sequence and charge indicator updated as expected after a full charge-discharge cycle.
- First-deployment cycle: After fitting the new battery, run at least one complete transaction cycle — including a receipt print — before putting the terminal into live service. The Nurit maps battery capacity during normal operation and needs one full power cycle to calibrate the charge indicator accurately.
Terminal rebooting mid-transaction after battery swap
The Nurit's receipt printer draws a sharp current spike the moment it fires the paper feed motor. On a new Ni-MH cell that has not yet been conditioned, this spike can briefly dip voltage below the BMS cutoff threshold, triggering a hard reboot. This is not a faulty battery — it is the cell's internal resistance behaving normally before the first few charge cycles reduce it. Run two or three full charge-discharge cycles and the voltage sag on printer motor start will fall within the BMS's acceptable window.
Terminal won't power on after sitting unused in storage
Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. A terminal left in a drawer for several months can drop the cell below the BMS recovery threshold — typically around 5.4V for a 7.2V pack — at which point the terminal will not respond to the power button at all. Connect the terminal to its mains charger and leave it for a minimum of 30 minutes before attempting to power on. If the charge LED shows activity, the BMS has recovered; allow a full charge cycle before use.
