Honeywell BAT-SCN07 Barcode Scanner Replacement Battery 3.7V 3400mAh

Honeywell BAT-SCN07 — 3.7V Li-ion Replacement Battery (BAT-SCN07, 50164357-001)

This is a 3.7V, 3400mAh Li-ion replacement for the Honeywell BAT-SCN07 battery pack. It fits Honeywell barcode scanners that use OEM part numbers BAT-SCN07 or 50164357-001. The cell matches the original voltage rail and physical footprint so the pack seats correctly in both the scanner and its cradle.

• BAT-SCN07 and 50164357-001 compatibility: Both OEM part numbers reference the same internal cell format, connector pinout, and BMS communication protocol. Scanners using either number draw from the same 3.7V rail, so one replacement cell covers both variants without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-and-transmit bursts to confirm the BMS handled the combined laser trigger and wireless radio inrush without tripping. Cell voltage held stable under rapid sequential scanning, and the protection circuit responded correctly to discharge floor events.
• First-shift preparation on pick-and-pack lines: Place the scanner in its cradle for a complete charge cycle before the first shift. Scan trigger inrush current peaks when the cell sits near minimum state of charge — a fully charged pack prevents false BMS trips that can misread as hardware faults during high-frequency scanning at shift start.

Cradle showing a charging error on a freshly installed pack

Honeywell cradle docks read contact resistance on the battery terminals before committing to a charge cycle. If the contacts on the new pack or the cradle bay have residue from storage or handling, the dock interprets the resistance spike as a fault and throws a charging error. Wipe the gold contacts on the battery with a dry cloth, reseat the pack firmly, and re-insert into the cradle. The charge indicator should switch to active within 15 seconds of a clean contact read.

Scanner dropping wireless connection during rapid scan bursts

During rapid barcode scanning, the scanner fires the imager and transmits data over its wireless radio almost simultaneously. That combined current draw creates a brief inrush spike that can drag cell voltage below the radio module's minimum operating threshold if the pack is already depleted. The BMS does not trip — the radio simply loses enough voltage to drop its connection, and the scanner appears to freeze mid-scan. Keep the pack above 20 percent charge during high-frequency scanning shifts to prevent the inrush from pulling voltage below 3.4V at the radio rail.
