Unitech PA968II 7.4V Replacement Battery 1400-900006G

Unitech PA968II — 7.4V Li-ion Replacement Battery (1400-900006G)

This is a 7.4V, 1800mAh Li-ion battery for the Unitech PA968II handheld barcode scanner. It replaces OEM part number 1400-900006G and fits the PA968II used in retail, warehouse, and logistics operations. The cell dimensions are 61.90 × 42.07 × 28.21mm — confirm these match your pack before ordering.

• PA968II platform fit: The PA968II uses a 7.4V two-cell Li-ion configuration with a BMS that validates voltage and temperature at startup. This pack matches that voltage rail and connector arrangement, so the scanner's power management circuit initialises normally on boot.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio draw events. The BMS held voltage above the scanner's minimum threshold throughout the test cycle and did not trip on combined inrush from the imager and radio simultaneously.
• First-shift preparation for pick-and-pack: Place the scanner in its cradle for a full charge cycle before deploying this pack on a shift. Scan-trigger inrush current peaks when the cell is near minimum charge, and a depleted new pack can cause false BMS trips during the first hour of heavy scanning.

Cradle showing a charging error on a new PA968II pack

The PA968II cradle reads charging status through the battery contacts on the base of the scanner. If those contacts have oxidation or debris from a worn-out pack, the dock may flag a contact resistance error instead of starting a charge cycle. Remove the pack, wipe the gold contacts on both the battery and the scanner with a dry cloth, then reseat firmly. If the error clears, the cradle will resume the charge handshake and begin charging normally.

Scanner losing wireless connection during rapid scan bursts

During rapid scanning, the PA968II draws simultaneously from the imager and the wireless radio — both spike current at nearly the same moment. A cell with degraded capacity cannot sustain that combined draw without voltage sag, and the radio module drops its connection before the imager does. This pack's 1800mAh rating keeps the voltage above the radio's dropout threshold during back-to-back scan events. If disconnects persist, charge the pack to full — 8.4V at pack terminals — before the next shift.
