Nautiz X4 Barcode Scanner Compatible Battery 3.7V 3600mAh

Nautiz X4 — 3.7V Li-ion Replacement Battery (60-BTSC / NX4-1004)

This 3.7V, 3600mAh Li-ion battery replaces the original 60-BTSC and NX4-1004 packs in the Nautiz X4 rugged handheld scanner. The X4 is a barcode scanner used in warehouse, logistics, and retail environments where multi-shift operation is common. Voltage, contact layout, and BMS communication match the X4 dock and device exactly.

• X4 platform fit: The X4 uses a single-cell 3.7V Li-ion architecture with a multi-pin BMS contact that reports state-of-charge to the host device and cradle. This pack carries the same contact layout and BMS handshake, so the scanner's charge indicator and battery status screen read correctly from the first cycle.
• Bench tested on actual hardware: We ran this pack through simulated scan-burst cycling — repeated laser trigger pulls combined with active wireless polling — and monitored BMS cutoff thresholds. The protection circuit held voltage above the X4's minimum operating threshold without nuisance trips under combined radio and imager load.
• First-shift preparation for the X4: After installing this pack, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush is highest when the cell is near minimum, and a fully charged cell prevents false BMS trips on the first burst of the day.

Cradle showing a charging error on a new pack

The X4 cradle reads state-of-charge through gold-pin contacts on the base of the pack. If those contacts have residue — from gloves, dust, or packaging film — the dock registers a communication fault and displays a charging error even though the pack itself is fine. Wipe the contacts on both the pack and the cradle with a dry cloth, then reseat firmly until you feel the pack lock. The error clears immediately once contact resistance drops back to normal and the BMS handshake completes.

Scanner losing wireless connection during rapid scan bursts

During a fast scan burst, the X4 draws current simultaneously from the imager, the wireless radio, and the internal processor. That combined inrush can cause a momentary voltage sag on a cell that is below 50% charge. When the voltage dips below the radio module's minimum threshold, the wireless stack drops and the scanner loses its connection to the host system. Charge the pack above 80% before starting a high-throughput picking session, and the voltage rail stays stable enough to support both loads without dropout.
