Honeywell 8800 Barcode Scanner Replacement Battery 3.7V 3400mAh

Honeywell 8800 — 3.7V Li-ion Replacement Battery

This 3.7V, 3400mAh lithium-ion battery replaces the original pack in the Honeywell 8800 barcode scanner. The 8800 is a handheld scanner used in retail, warehouse, and inventory environments where the device runs for extended shifts. Capacity matches the stock specification so the scanner's power management system does not flag a mismatch on boot.

• 8800 platform fit: The 8800 uses a dedicated battery bay with a fixed contact layout and BMS handshake tied to cell identification. This pack carries the correct cell chemistry and contact configuration to complete that handshake without triggering a fault code on the scanner's status display.
• Bench tested on actual hardware: We cycled this pack through repeated scan bursts and wireless polling loads. The BMS held the output rail steady through combined radio and laser draw without dropping into protective cutoff.
• First shift startup tip: Place the scanner in its cradle and run a full charge cycle before putting it on the pick floor. The scan trigger inrush current is highest when the cell sits near minimum charge, and a fully charged pack prevents a false BMS trip during the first burst sequence of the shift.

Cradle showing a charging error on a new pack

A charging error on the dock after a battery swap is almost always a contact resistance issue, not a fault with the cell itself. The cradle's charge controller reads contact voltage to confirm the pack is seated — oxidation or dust on the gold contacts raises resistance enough to trigger the error. Wipe the battery contacts and the cradle terminals with a dry cloth, then reseat the scanner firmly until the dock clicks. If the error clears within 30 seconds, the cell is charging normally at 3.7V nominal.

Scanner losing wireless connection during rapid scan bursts

During a fast burst sequence, the scanner draws current for both the imager and the wireless radio simultaneously. If the cell voltage sags under that combined load, the radio module is first to drop — the scanner appears to scan but transmissions stop reaching the access point. This shows up as missed records in the WMS rather than an obvious error on screen. Check the battery indicator before the shift; anything below two bars means the combined inrush will cause sag, and the pack should be swapped or charged to at least 3.9V before the session starts.
