Triton 9100 POS Terminal Replacement Battery 3.6V 5400mAh

Triton 9100 / 9600 / 9700 / FT5000 X2 — 3.6V Li-MnO2 Replacement Battery (01300-00023)

This is a 3.6V, 5400mAh lithium manganese dioxide battery for Triton payment terminals, including the 9100, 9600, 9700, and FT5000 X2 series. It replaces OEM part number 01300-00023. The battery powers the terminal's display, card reader, receipt printer, and wireless stack during portable operation.

• 9100 / 9600 / 9700 / FT5000 X2 platform fit: These terminals share the same 3.6V single-cell architecture and connector pinout, which is why one battery covers all listed models. The BMS handshake protocol is identical across the series, so the cell registers correctly on first boot without any firmware adjustment.
• Bench tested on actual hardware: We ran this cell through full boot-to-shutdown cycles on a Triton 9100 unit. The BMS accepted the cell without a fault flag, the charge IC entered normal top-off mode, and the receipt printer's motor draw did not trigger an overcurrent cutoff.
• First deployment cycle on the terminal: After installation, complete one full transaction cycle — card read, printer output, and display active — before putting the terminal into live service. The terminal 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

When the receipt printer motor fires, it pulls a short current spike that a freshly installed cell's BMS can interpret as an overcurrent event. This trips a protective cutoff and forces a reboot mid-sale. The fix is to run several test transactions immediately after installation so the BMS logs the printer's draw profile as within normal operating range. Once the BMS has seen that pattern two or three times, mid-transaction reboots stop.

Terminal not powering on after sitting unused in a drawer

Li-MnO2 cells self-discharge slowly during storage, and a terminal left unused for several months can drop below the BMS recovery threshold — typically around 2.8V. At that point the terminal will not respond to the power button at all. Connect the terminal to its dock or AC adapter and leave it for 30–45 minutes before attempting a power-on; most chargers in this class include a pre-charge trickle mode that brings the cell back above the 3.0V re-initialisation threshold before switching to normal charge current.
