LXE FX1380 Barcode Scanner Replacement Battery 11.1V 1800mAh

LXE FX1380 — 11.1V Li-ion Replacement Battery

This 11.1V 1800mAh Li-ion battery replaces the original pack in the LXE FX1380 handheld barcode scanner. The FX1380 is a mobile data collection device used in warehouse, logistics, and retail pick-and-pack environments. Voltage and capacity match the original specification to keep the scanner running through full shift cycles.

• FX1380 fit confirmation: The FX1380 runs an 11.1V three-cell Li-ion pack at 1800mAh. This replacement matches that voltage rail and connector footprint. The BMS in the host device monitors cell voltage through the pack's internal protection circuit — a mismatched voltage rail will trigger a shutdown at first boot.
• Bench tested on actual hardware: We cycled this pack through scan trigger inrush loads and sustained wireless polling draw. The BMS held cutoff voltage cleanly and did not false-trip during the combined radio-plus-trigger burst that typically stresses lighter cells near minimum charge.
• First-shift preparation for the FX1380: After installing this pack, seat the scanner in its charging cradle and run a full charge cycle before the first shift. Scan trigger inrush current is highest when the cell is near minimum — a fully charged cell prevents false BMS trips during the first pick run of the day.

Cradle showing a charging error on a new pack

LXE cradles communicate with the battery through contact pins on the base of the scanner. If those contacts carry oxidation or debris from the old pack, the cradle misreads resistance and flags a charging fault. This is not a fault with the new cell — it is a contact issue. Wipe the gold contacts on both the battery and the cradle dock with a dry cloth, then reseat the scanner firmly. The charging indicator should clear within 30 seconds of a clean seating.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan burst, the FX1380 draws current from the imager and the wireless radio simultaneously. If the pack voltage sags below approximately 9V under that combined load, the radio module drops its connection before the BMS triggers a full shutdown. This produces an intermittent disconnect rather than a clean power-off, which makes it easy to misread as a network issue. If this happens repeatedly, charge the pack to full — 12.6V at the terminals — before the next shift and monitor whether the dropouts stop.
