Honeywell BAT-SCN02 8680i Replacement Battery 3.8V 2100mAh

Honeywell 8680i Smart Wearable Scanner — 3.8V Li-ion Replacement Battery (BAT-SCN02)

This 3.8V 2100mAh Li-ion cell replaces the OEM pack in the Honeywell 8680i and 8680i Smart Wearable Scanner. It matches the original voltage rail and connector footprint for the worn-on-hand form factor used in pick-and-pack and inventory operations. Capacity is sourced from the product specification — 2100mAh (7.98Wh).

• 8680i and 8680i Smart Wearable compatibility: Both scanner variants run the same 3.8V power bus and share the BAT-SCN02 and BAT-SCN03 OEM part numbers. The BMS handshake, connector pinout, and cell dimensions (56.05 × 53.70 × 19.90mm) are identical across the two models, so one replacement covers both.
• Bench tested on actual hardware: We cycled the pack through combined wireless polling and rapid scan-trigger draws. The BMS held stable through burst-scan sequences and did not trip on the inrush current spike produced when the scan engine fires at low cell voltage.
• First-shift preparation for wearable scanners: After installing, seat the scanner in its charging cradle and complete a full charge cycle before the shift begins. The scan trigger inrush current is highest when the cell sits near minimum voltage — a fully charged cell prevents false BMS trips during the first heavy pick run of the day.

Cradle showing a charging error on a new pack

The 8680i cradle reads battery state through the dock contacts on the underside of the pack. If those contacts carry oxidation or assembly residue from shipping, the cradle throws a charging fault even when the cell itself is fine. Wipe the gold contacts on both the battery and the cradle bay with a dry lint-free cloth, then reseat the scanner firmly until you hear the click. The dock should begin a charge cycle within 10 seconds of a clean contact seating.

Scanner dropping wireless connection mid-scan burst

The 8680i fires both the scan engine and the wireless radio simultaneously during a rapid burst sequence. The combined inrush draw can cause a momentary voltage sag on a partially depleted cell, which the BMS interprets as an undervolt event and briefly cuts output. This shows up as a dropped Bluetooth or Wi-Fi link right after a series of fast trigger pulls. Start the shift with a fully charged pack — a cell sitting above 3.7V handles the combined draw without sag.
