ITRON FC300 Barcode Scanner Replacement Battery 11.1V 2600mAh

ITRON FC300 — 11.1V Li-ion Replacement Battery

This is an 11.1V, 2600mAh (28.86Wh) Li-ion battery for the ITRON FC300 mobile data terminal. The FC300 is a handheld barcode scanner used in retail, warehousing, and inventory management. This pack slots directly into the FC300 and works with the existing cradle charging setup.

• FC300 platform fit: The FC300 runs an 11.1V three-cell Li-ion configuration with a battery management system that monitors individual cell voltage. Replacing with the correct cell count and nominal voltage keeps the BMS from flagging a pack mismatch and refusing to charge.
• Bench tested on actual hardware: We cycled this pack through scan-trigger and wireless radio draw simultaneously. The BMS held cell balance across discharge and did not trip on the combined inrush from the imager and radio transmitter firing together during burst scanning.
• First-shift prep for the FC300: After installing this pack, seat the scanner in its cradle and let it complete a full charge cycle before pulling it for a pick-and-pack shift. Scan trigger inrush is highest when the cell sits near minimum voltage — a fully charged pack on install prevents a false BMS trip during the first heavy scan burst of the shift.

Cradle showing a charging error on a new FC300 pack

The FC300 cradle communicates with the battery over a data contact alongside the power pins. If that contact has oxidation or debris, the dock reads a handshake fault and throws a charging error — even with a healthy new pack seated correctly. The cradle does not distinguish between a failed battery and a dirty contact; it stops the charge cycle either way. Wipe the gold contacts on the battery and the cradle bay with a dry lint-free cloth, reseat the pack firmly, and the error clears in most cases. If the error persists after cleaning, reseat the pack once more and check that the cradle power supply is outputting the correct voltage — the FC300 dock requires a stable supply to initiate the handshake.

FC300 losing wireless connection during rapid scan bursts

During a rapid scan burst, the FC300 draws from the imager and the wireless radio at the same time. If the battery is partially discharged, that combined inrush can cause a momentary voltage sag that drops below the radio module's operating floor — the wireless link drops and the scanner must re-associate with the access point. This is not a scanner fault or a network fault; it is a battery voltage floor issue. Keep the pack above 20% state of charge during high-frequency scanning shifts, and the radio draw stays within the BMS's steady-state current window without triggering a sag cutoff.
