Newland N910 LD18650A Replacement Battery 7.4V 2600mAh

Newland N910 / N900 / N510 / N920 — 7.4V Li-ion Replacement Battery (LD18650A)

The LD18650A is a 7.4V, 2600mAh Li-ion battery for the Newland N910, N900, N510, and N920 payment terminals. These are handheld POS devices used in retail and service environments to process card transactions. When the original cell degrades, this replacement restores normal operating capacity so the terminal can complete transactions without unexpected shutdowns.

• N910 / N900 / N510 / N920 compatibility: These four Newland terminals share the same battery bay dimensions, connector pinout, and BMS communication protocol. The LD18650A part number is common across the range — the voltage rail and handshake logic are identical on each model.
• Bench tested on actual hardware: We ran the LD18650A through charge cycles and simulated transaction loads including printer motor draws and wireless polling. The BMS held protection thresholds correctly and did not trip under combined display, printer, and radio load.
• First deployment tip for POS terminals: After installation, complete one full transaction cycle before deploying in a live environment. 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 battery swap

A mid-transaction reboot on a fresh battery is almost always a BMS overcurrent trip, not a faulty cell. The receipt printer motor draws a sharp current spike the moment it fires — on a new battery, the BMS protection threshold is conservative until the cell has completed its first full charge-discharge cycle. The terminal interprets the BMS cutoff as a power loss and restarts. Run two or three complete charge cycles before live deployment and the trip threshold normalises.

Terminal not completing PCI boot sequence on new battery

Some Newland terminals perform a PCI security boot check that requires a confirmed power source before completing initialisation. A brand-new cell can present a voltage signature the charge IC hasn't yet accepted, stalling the boot sequence at the security handshake stage. The fix is to charge the terminal to full with the device powered off, then power on — this gives the charge IC time to complete its acceptance cycle before the PCI check runs. Once the terminal boots successfully from a full charge, the issue does not repeat.
