Datalogic Powerscan 4220 Compatible Battery 3.7V 1800mAh

Datalogic Falcon 4220 / 4223 Series — 3.7V Li-ion Replacement Battery (95A201001)

This 3.7V, 1800mAh Li-ion battery replaces the original pack in the Datalogic Falcon 4220 and Falcon 4223 handheld barcode scanners, as well as the C45 model. It matches OEM part number 95A201001 and fits directly into the existing battery compartment without modification.

• Falcon 4220, 4223, and C45 compatibility: These models share the same 3.7V battery rail, physical footprint, and connector orientation. The BMS handshake protocol is identical across the group, so one cell revision covers all three without reflashing or adapter cables.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Falcon 4220 platform. The BMS held protection thresholds correctly, and the cell voltage stayed stable through repeated scan-trigger inrush events without tripping an overcurrent cutoff.
• First-shift preparation for pick-and-pack environments: After installing, seat the scanner in its cradle for a full charge cycle before putting it into rotation. Scan trigger inrush current peaks when the cell is near minimum charge — a pre-charged pack prevents false BMS trips at the start of the first shift.

Cradle showing a charging error on a new pack

Charging docks on the Falcon series read contact resistance at the battery terminals before allowing current flow. If the dock returns an error on a fresh pack, the most likely cause is oxidation or contamination on the battery's gold contacts. Wipe both the pack contacts and the cradle pins with a dry lint-free cloth, then reseat the scanner firmly. The dock should acknowledge the pack within 30 seconds and begin charging normally.

Scanner losing wireless connection during rapid scan bursts

The Falcon 4220 draws from the same cell for both the radio transmitter and the scan trigger simultaneously. During rapid back-to-back scans, that combined inrush load can push a weakened or partially charged cell below the radio module's minimum supply voltage, dropping the wireless link. The scanner may re-associate automatically, but repeated drops mid-shift point to a cell that can no longer sustain combined peak draw. Charge the replacement pack fully before use and verify resting voltage reads at least 3.9V before deploying on the floor.
