About this replacement
Honeywell Xenon Ultra 1962g — 3.7V Li-ion Replacement Battery (BAT-SCN11WC)
This is a 3.7V Li-ion replacement battery rated at 3300mAh (12.21Wh) for the Honeywell Xenon Ultra 1962g handheld barcode scanner. It replaces OEM part BAT-SCN11WC and fits the 1962g's battery compartment directly. The 1962g is a 1D/2D area-imaging scanner used in retail, warehouse, and logistics operations.
- Xenon Ultra 1962g platform fit: The 1962g runs its imager, wireless radio, and scan trigger from the same 3.7V cell. This pack matches the original voltage rail and connector pinout, so the BMS handshake completes and the scanner powers on without an error state.
- Bench tested on actual hardware: We cycled this pack through repeated scan-trigger events and wireless polling loads. The BMS handled combined inrush from the imager and radio without tripping into protection mode under normal operating conditions.
- First-install charge cycle: After installing, seat the scanner in its charging cradle and run a full charge cycle before starting a pick-and-pack shift. Scan-trigger inrush current is highest when the cell is near minimum charge, and a fully charged cell prevents false BMS trips on your first scan burst.
Cradle showing a charging error on a new pack
A charging error on the cradle dock does not always mean a faulty battery. The 1962g's cradle communicates with the pack over the battery contacts, and any film, residue, or oxidation on those contacts raises resistance enough to break the handshake. Wipe the gold contacts on both the battery and the cradle slot with a dry lint-free cloth, then reseat the scanner firmly. If the error clears within 30 seconds of reseating, contact resistance was the cause — the cell itself is fine.
Scanner losing wireless connection during rapid scan bursts
During a fast scan burst, the 1962g draws current from two sources simultaneously: the area imager firing and the Bluetooth or 802.11 radio transmitting the decoded data. On a depleted or degraded cell, that combined inrush pulls the cell voltage below the radio's minimum operating threshold, causing the wireless link to drop mid-session. The scanner may still read the barcode locally but fails to transmit it. Charge the pack to at least 3.9V before the shift to keep the cell above the dropout point under combined load.
