HandHeld Nautiz X5 eTicket NX5-2004 Compatible Battery 3.7V 6400mAh

HandHeld Nautiz X5 eTicket — 3.7V Li-ion Replacement Battery (NX5-2004)

This is a 3.7V Li-ion 6400mAh battery for the HandHeld Nautiz X5 eTicket rugged mobile computer. It fits the Nautiz X5 eTicket directly and matches the OEM part numbers NX5-2004, J62510N0272, and 6251-0A. The Nautiz X5 eTicket is a field-grade barcode scanner and data terminal used in logistics, ticketing, and outdoor data collection.

• Nautiz X5 eTicket compatibility: The X5 eTicket uses a fixed 3.7V cell with a specific BMS handshake that controls scan trigger power and wireless radio output. This pack matches that voltage rail and connector exactly — the BMS initialises without faults on insertion.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst and wireless polling sequences. The BMS held the voltage rail stable across sustained trigger pulls and did not trip during combined radio and imager draw.
• First-shift preparation: After installing this pack, place the Nautiz X5 eTicket in its cradle for a full charge cycle before deploying it. Scan trigger inrush current is highest when the cell is near minimum — a pre-charged pack prevents false BMS trips on the first shift in the field.

Cradle showing a charging error on a new pack

Charging errors on the Nautiz X5 eTicket cradle after a battery swap are almost always a contact resistance issue, not a pack fault. Debris or oxidation on the battery's gold contacts raises resistance above the dock's threshold, and the charger reads it as a fault condition. Remove the pack, wipe all contacts on both the battery and cradle with a dry cloth, and reseat firmly. If the error clears, the pack was never the problem.

Scanner losing wireless connection during rapid scan bursts

The Nautiz X5 eTicket draws from the same cell for both the imager and the wireless radio simultaneously. During rapid back-to-back scans, the combined inrush can pull the cell voltage below the radio module's minimum operating threshold — the radio drops out first because the imager gets priority from the BMS. This is more common when the pack is below 20% charge. Keep the pack above 3.6V during heavy pick-and-pack shifts to prevent the radio from dropping mid-transmission.
