HandHeld Nautiz X8 Barcode Scanner Replacement Battery 3.7V 6800mAh

HandHeld Nautiz X8 — 3.7V Li-ion Replacement Battery (162403210)

This is a 3.7V 6800mAh Li-ion battery for the HandHeld Nautiz X8 rugged mobile computer. It fits the Nautiz X8 used in logistics, inventory management, and field data collection. Part numbers 162403210, NX8-1004, BP14-001200, and BAT-G2-003 all cross-reference to this pack.

• Nautiz X8 platform fit: The X8 runs a single-cell 3.7V architecture shared across its hardware revisions. All listed OEM part numbers reference the same voltage rail, connector pinout, and BMS handshake protocol — one pack covers the platform.
• Bench tested on actual hardware: We cycled this pack through scan-burst sequences and monitored the BMS response under combined wireless radio and imager draw. The protection circuit held stable at low state-of-charge without tripping into lockout during high-inrush trigger events.
• First-shift preparation on the Nautiz X8: After installing this pack, seat the X8 in its charging cradle and complete a full charge cycle before starting a pick-and-pack shift. The scan trigger pulls the highest inrush current when the cell is near minimum — a fully charged cell prevents false BMS trips on the first few scans of the day.

Cradle showing a charging error on the new pack

Charging docks on the Nautiz X8 read pack state through the contact pads on the battery base. If those contacts have oxidation, dust, or residue from a degraded old pack, the dock can misread the new cell's state and throw a charging fault. Wipe the gold contacts on the battery and the dock with a dry lint-free cloth, then reseat the unit firmly. If the error clears within 60 seconds, the contacts were the issue — not the pack or the dock firmware.

Scanner losing wireless connection during rapid scan bursts

The Nautiz X8 runs its wireless radio and its barcode imager simultaneously during fast scanning. Each scan trigger pulls a brief current spike on top of the constant radio polling load — the combined draw can cause momentary voltage sag on a weakened or deeply discharged cell. The BMS interprets that sag as an unsafe condition and reduces output, which briefly starves the radio and drops the connection. Charge the pack to full before a high-volume scan shift and check that the pack rests above 3.6V at idle before use.
