Falcon SB-320 Barcode Scanner Replacement Battery 3.6V 2500mAh

Falcon 310 / 315 / 320 / 325 Series — 3.6V Ni-MH Replacement Battery (SB-320)

This 3.6V Ni-MH battery replaces the SB-320 pack in Falcon 310, 315, 320, and 325 series barcode scanners. Capacity is 2500mAh (9Wh), matching the original specification. It fits handheld scanners used in warehouse, retail, and inventory environments.

• 310–325 series compatibility: These models share the same battery bay geometry, connector orientation, and 3.6V single-cell Ni-MH voltage rail. The SB-320 form factor seats identically across the range, so one part number covers the full scanner lineup without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge passes on the 310 platform. The BMS accepted charge via the cradle dock without triggering a fault condition, and the scan trigger and wireless radio drew current within expected parameters across the test run.
• First-shift prep for pick-and-pack operations: Place the scanner in its charging cradle for a complete charge cycle before putting it into active use. The scan trigger inrush current peaks when the cell is near minimum voltage — a fully charged cell prevents false BMS trips during the first high-demand shift.

Cradle showing a charging error on a new SB-320 pack

Ni-MH packs shipped in storage-discharge state can present a voltage low enough that some Falcon cradles flag an error instead of starting a charge cycle. This happens because the dock's charge controller checks cell voltage before initiating current flow, and a deeply discharged pack reads outside the expected window. Remove the scanner, wipe the gold contacts on both the battery and the cradle bay with a dry cloth, then reseat firmly. If the error persists, hold the pack at room temperature for 15 minutes and reseat — most cradles will clear the fault once contact resistance drops and the cell recovers above 3.0V.

Scanner losing wireless connection during rapid scan bursts

When the scan trigger fires rapidly, the imager and the wireless radio both draw current simultaneously, creating a combined inrush load the cell has to meet in milliseconds. A partially charged or degraded Ni-MH cell sags in voltage under this combined load, which drops the radio module below its minimum operating threshold and breaks the wireless link. The fix is straightforward — ensure the pack is charged above 80% before a high-volume scanning session. If disconnects happen even with a full charge, check that the battery contacts inside the scanner bay are clean and making firm contact, as resistance at that junction amplifies voltage sag under load.
