Datalogic Falcon X3 Compatible Battery 3.7V 4400mAh

Datalogic Falcon X3 / X3+ / X4 — 3.7V Li-ion Replacement Battery (94ACC1386)

This 3.7V, 4400mAh lithium-ion battery replaces the original pack in the Datalogic Falcon X3, Falcon X3+, and Falcon X4 handheld barcode scanners. It matches OEM part numbers 94ACC1386, BT-26, 4ACC0046, and BT-0016. These scanners are used in warehouse pick-and-pack, retail stockrooms, and logistics operations where a dead pack stops the shift.

• Falcon X3 / X3+ / X4 platform fit: All three models share the same battery bay dimensions, contact layout, and BMS handshake protocol. One pack covers the whole platform — no adapter or firmware change needed.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the Falcon X3. The BMS held voltage within spec under combined scan-trigger and wireless radio load, and protection circuits tripped correctly at low-voltage cutoff without false shutdowns.
• First-shift prep for scan trigger inrush: After installing, seat the scanner in its cradle and run a complete charge cycle before taking it onto the floor. The scan trigger draws a short inrush current spike each time it fires — a partially charged new cell near minimum voltage can trip the BMS on the first burst scan sequence of the day.

Cradle showing a charging error on a new pack

Charging docks on the Falcon X3 series read pack state through the contact pins on the battery base. If those contacts have oxidation or residue from the old pack, the dock may report a fault even though the new battery is fully functional. Wipe the gold contacts on the battery and the cradle bay with a dry lint-free cloth, then reseat the scanner firmly so all pins engage flush. If the error clears within 30 seconds of reseating, the contacts were the cause — not the cell. A persistent error after clean contact seating points to the dock itself, not the battery.

Scanner losing wireless connection during rapid scan bursts

The Falcon X3 runs its Wi-Fi radio and scan imager from the same cell simultaneously. During a rapid burst scan — multiple triggers fired in quick succession — the combined current draw can cause a brief voltage sag on an aged or undercharged cell. The radio stack drops connection when supply voltage dips below its minimum threshold, even if the scanner itself stays on. A fresh, fully charged 4400mAh cell handles the combined load without the sag. If dropouts continue on a fully charged new pack, check the wireless polling interval in the device settings — shortening the beacon period reduces radio draw during scan bursts.
