HandHeld Nautiz X5 eTicket Compatible Battery 3.7V 5200mAh

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

This is a 3.7V 5200mAh Li-ion battery for the HandHeld Nautiz X5 eTicket rugged handheld scanner. It fits the NX5-2004, J62510N0272, and 6251-0A part references. The Nautiz X5 eTicket is used in transportation ticketing, event access, and logistics field work where the scanner runs continuous scan-and-transmit cycles across a full shift.

• Nautiz X5 eTicket platform fit: The X5 eTicket uses a single-cell 3.7V pack with a BMS that monitors cell voltage and temperature independently from the dock charger. All three OEM part numbers above reference the same cell format, connector pinout, and BMS handshake protocol — no firmware pairing required after swap.
• Bench tested on actual hardware: We cycled this pack through combined wireless polling and imager trigger loads. The BMS held stable across repeated scan bursts without tripping the low-voltage cutoff, and the protection circuit responded correctly to simulated over-discharge at 2.75V per cell.
• First shift preparation for pick-and-pack use: After installing, seat the scanner in its cradle and run a full charge cycle before taking it onto the floor. The imager trigger draws peak inrush current at low state-of-charge — a pre-charged cell prevents a false BMS trip on the first scan burst of the shift.

Cradle showing a charging error on a new pack

The Nautiz X5 eTicket dock reads battery state through spring-loaded contact pins on the base of the scanner. If contact resistance is too high — from oxidation, debris, or a slightly misaligned seating — the dock flags a charging fault even though the pack is functional. Wipe the gold contacts on the battery and on the dock with a dry cloth, then reseat the unit firmly until you hear the retention click. If the error clears within 30 seconds of reseating, the pack is fine and the fault was contact-related, not a cell problem.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the imager trigger and the wireless radio fire simultaneously — this combined inrush can cause a brief voltage sag on a partially charged pack. The Nautiz X5 eTicket's BMS interprets a sag below its lower threshold as an unsafe condition and briefly interrupts output, which drops the wireless session before the scanner recovers. This is most common when the pack is below 30% charge. Keep the pack above that level during high-frequency scan shifts, and confirm resting voltage is at or above 3.6V before starting a session.
