About this replacement
VeriFone VX610 / VX510 — 7.4V Li-ion Replacement Battery (23326-04)
This 7.4V 1800mAh Li-ion battery replaces the original power cell in the VeriFone VX610 and VX510 payment terminals. It fits the standard VX610 wireless terminal and matches OEM part numbers 23326-04, 23326-04-R, and LP103450SR+321896. Swap it in when the original cell no longer holds enough charge to carry a full business day of transactions.
- VX610 and VX510 platform fit: Both terminals share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. One cell covers both devices without any wiring or adapter changes.
- Bench tested on actual hardware: We cycled this cell through the VX610 boot sequence and a series of card transactions. The BMS accepted the handshake on first boot, voltage stayed stable under combined wireless, display, and printer draw, and the charge indicator tracked correctly after one full charge cycle.
- First transaction cycle after installation: Complete one full transaction — from power-on through receipt print — before deploying the terminal in a live environment. The VX610 maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.
Terminal not completing PCI boot sequence after battery swap
The VX610 runs a PCI-compliant boot check on every startup that includes a battery voltage verification step. A brand-new cell can sit slightly below the threshold the BMS reports as "ready" until it completes its first full charge cycle. If the terminal stalls at the boot screen or shows a battery fault, connect it to the charging dock and let it reach 100% before powering on again. One full charge resolves this in nearly every case.
Terminal rebooting mid-transaction during receipt printing
The thermal receipt printer in the VX610 draws a short, sharp current spike when it fires the print head — this can trip the BMS overcurrent cutoff if the cell voltage has already sagged under the combined load of the wireless radio and display. The terminal reads this as a power loss and reboots. If this happens consistently during printing, check that the cell is fully charged before a busy period; a cell reading below 7.0V under load is at the edge of the BMS cutoff window and should be replaced.
