Honeywell MX9383 Replacement Battery 11.1V 2600mAh

Honeywell MX9380 Series — 11.1V Li-ion Replacement Battery (161888-0001)

This 11.1V 2600mAh Li-ion battery replaces the original pack in the Honeywell MX9380, MX9381, MX9382, and MX9383 handheld barcode scanners. It matches the OEM voltage, connector, and BMS communication protocol used across this scanner family. Capacity is 2600mAh (28.86Wh) — consistent with the original specification.

• MX9380–MX9383 platform fit: All four models share the same 11.1V cell configuration, battery bay dimensions, and BMS handshake sequence. The connector pinout and charge termination logic are identical across the series, so one pack services the entire range without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio load events on the MX9383. The BMS held voltage within spec during combined inrush bursts and terminated charge cleanly at full capacity without flagging a fault condition.
• First-shift cradle conditioning: After installing this pack, place the scanner in its cradle for a full charge cycle before putting it into pick-and-pack use. Scan trigger inrush current peaks when the cell is near minimum — a fully charged cell prevents false BMS trips during the first shift's opening scans.

Cradle showing a charging error on a new pack

The MX9380 series cradle reads battery state through the dock's charge contacts before initiating the charge cycle. If those contacts carry oxidation or debris from the old pack, the cradle sees high contact resistance and throws a charge fault rather than starting. Wipe the battery's gold contacts and the cradle's pins with a dry lint-free cloth, then reseat the scanner firmly until it clicks. If the error clears within 30 seconds, contact resistance was the cause — not the pack itself.

Scanner losing wireless connection during a rapid scan burst

During a rapid barcode scan sequence, the MX9383 draws simultaneously from both the imager and the wireless radio. That combined inrush can drag cell voltage low enough to trigger a momentary BMS protection event, which the scanner interprets as a connection drop rather than a power event. This is most common when the battery is below 30% charge or when the cell is cold — below 10°C. Start shifts with a fully charged pack and keep the scanner away from unheated dock areas to hold cell voltage above the 9.8V BMS floor during peak draw.
