About this replacement
Honeywell Xenon Ultra 1960 / 1962 — 3.7V Li-ion Replacement Battery (BAT-SCN11)
This is a 3.7V 3300mAh Li-ion replacement for the BAT-SCN11 pack used in the Honeywell Xenon Ultra 1960, Xenon Ultra 1962, and Xenon Ultra 1960 Corded 2D handheld barcode scanners. These scanners run in retail, logistics, and warehouse inventory workflows where continuous scanning across shifts is the baseline expectation. Swapping this pack restores full imaging and wireless function when the original cell can no longer hold a working charge.
- Xenon Ultra 1960 / 1962 / 1960 Corded 2D platform: All three models share the same BAT-SCN11 form factor, contact pinout, and BMS handshake protocol. The scanner's firmware reads cell identification data from the pack on insertion — this battery returns the correct response so the scanner does not flag an incompatible or unknown pack.
- Bench tested on actual hardware: We cycled this pack through repeated scan-burst sequences on the Xenon Ultra platform. The BMS handled the combined inrush from the imager and the wireless radio without tripping into protection mode, and the cell voltage held stable through sustained high-frequency scanning.
- First-shift cradle protocol: After installing this pack, seat the scanner in its charging cradle and run a full charge cycle before using it on a pick-and-pack shift. The scan trigger draws its highest inrush current when the cell is near minimum charge — starting the first shift on a fully charged pack prevents false BMS protection trips during the first hour of heavy use.
Cradle showing a charging error on a freshly installed pack
Honeywell charging cradles monitor contact resistance on every dock cycle. If the gold contacts on the battery or cradle have any oxidation, handling oils, or warehouse dust on them, the cradle registers a resistance threshold fault and refuses to charge. This is not a battery fault — it is a contact fault. Wipe the battery contacts and the cradle contacts with a dry lint-free cloth, then reseat the pack firmly until the cradle LED confirms a charge state. If the error clears immediately after cleaning, the contacts were the issue.
Scanner losing wireless connection during rapid scan bursts
The Xenon Ultra 1960 draws current from two sources at once during a fast scan sequence — the 2D imager illumination and the Bluetooth or 802.11 radio polling simultaneously. On a degraded or low cell, this combined inrush can pull voltage below the BMS protection floor, causing the radio to drop the connection even though the scanner appears powered on. A fresh, fully charged pack raises the stable voltage floor high enough that both loads run concurrently without a dropout. If dropouts persist on a charged pack, check the wireless polling interval in the scanner configuration — reducing it lowers the combined peak draw.
