Honeywell 8800 Barcode Scanner Replacement Battery 3.7V 2200mAh

Honeywell 8800 — 3.7V Li-ion Replacement Battery

This 3.7V 2200mAh Li-ion battery replaces the depleted pack in the Honeywell 8800 handheld barcode scanner. The 8800 is a mobile computer terminal used in retail, warehouse, and logistics environments for barcode reading and inventory data transmission. Voltage and capacity match the original spec exactly.

• 8800 platform fit: The 8800 series runs on a single-cell 3.7V Li-ion rail with a BMS that monitors cell voltage and current draw during both wireless radio polling and scan trigger bursts. A replacement pack must match the nominal voltage and present the correct impedance profile to avoid false low-battery flags during high-draw scan cycles.
• Bench tested on actual hardware: We cycled this pack through simulated scan bursts alongside wireless radio polling events to confirm the BMS did not trip on combined inrush. The cell held voltage above the cutoff threshold across repeated trigger pulls without dropping into protective shutdown.
• First-shift preparation: After installing, seat the scanner in its charging cradle and run a full charge cycle before putting it into a pick-and-pack rotation. Scan trigger inrush current is highest when the cell is near minimum charge — a fully conditioned pack prevents false BMS trips during the first shift's opening burst of scans.

Cradle showing charging error on a new pack

Charging docks on the 8800 use contact pins that oxidise with repeated insertions. A new pack with clean contacts seats into a dirty dock and the contact resistance rises enough for the dock to flag a charging fault — the pack itself is fine. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the scanner firmly until it clicks. The dock should clear the error and begin charging within 30 seconds of a clean connection.

Scanner losing wireless connection during rapid scan bursts

The 8800 draws from the same cell to power both the imager and the wireless radio. During rapid scan sequences, the combined inrush from the trigger and the radio transmitter can pull the cell voltage low enough that the radio drops its connection to the access point. This is not a radio fault — it is voltage sag under peak load. If the drop happens repeatedly, check that the replacement pack is fully charged before the shift starts, since a partially charged cell has higher internal resistance and sags further under the same load.
