Honeywell MX9383 Replacement Battery 11.1V 3400mAh

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

This 11.1V, 3400mAh Li-ion battery replaces the original pack in the Honeywell MX9380, MX9381, MX9382, and MX9383 mobile computers. These are rugged handheld barcode scanners used in warehouse, retail, and logistics environments. It matches the original voltage and capacity to keep the device operating through a full shift.

• MX9380 series compatibility: All four models — MX9380 through MX9383 — share the same battery bay geometry, 11.1V voltage rail, and BMS handshake protocol. One pack fits the entire series without any modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the MX9383 platform. The BMS communicated correctly with the host device, accepted a full charge without error flags, and held voltage within spec under simulated scan-burst loads.
• First-shift cradle procedure: After installing the new pack, seat the scanner in its charging cradle for a complete charge cycle before starting pick-and-pack work. The scan trigger draws the highest inrush current when the cell is near minimum charge, and a fully charged cell prevents false BMS cutoffs during the first shift.

Cradle showing a charging error on a new pack

Charging docks on the MX9380 series use a contact-pin array that can accumulate oxidation or debris between battery swaps. A new pack with clean contacts can still trip a dock error if the dock-side pins have residue — the dock reads elevated contact resistance and flags it as a pack fault. Wipe the gold contacts on both the battery and the dock slot with a dry lint-free cloth, then reseat the pack firmly until it clicks. If the error clears, the dock contacts were the cause, not the battery.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan sequence, the MX9383 draws current simultaneously from the imager, the CPU, and the wireless radio. That combined inrush can cause a momentary voltage sag on a partially charged or degraded pack, and the radio module is the first subsystem to drop out when rail voltage dips. The BMS may also interpret the surge as an overload event and throttle output. Charge the pack to full before high-volume scanning shifts, and check that the battery contacts are seated flush — a loose connection amplifies voltage drop under load.
