HandHeld Quick Check QC150 Replacement Battery 4.8V 200mAh

HandHeld Quick Check QC150 / QC200 — 4.8V Ni-MH Replacement Battery (31203342-01)

This is a 4.8V, 200mAh Ni-MH replacement battery for the HandHeld Quick Check QC150 and QC200 barcode scanners. It replaces OEM part 31203342-01 and fits the compact battery bay on both models. Use it in retail, warehousing, or logistics pick operations where the original pack no longer holds charge.

• QC150 and QC200 shared platform: Both models run the same 4.8V Ni-MH cell stack with an identical connector and battery bay footprint. One part number covers both units — no adapter or modification needed.
• Bench tested on actual hardware: We cycled this pack through scan-trigger inrush events at low state of charge. The BMS held stable across repeated bursts without tripping into protection mode or dropping below the scanner's minimum operating voltage.
• First-install cradle cycle: After installing this pack, seat the scanner in its cradle and complete a full charge cycle before starting a shift. The scan trigger inrush current peaks when the cell is near minimum, and a fully charged pack prevents false BMS trips on the first heavy scan burst.

Cradle showing a charging error on a new pack

The QC150 cradle reads pack voltage through contact pins on the battery face. If those contacts carry oxidation or residue from the previous pack, the dock sees elevated resistance and flags a charging fault. This is a contact issue, not a battery fault. Wipe the gold contacts on the new pack and the cradle dock with a dry cloth, then reseat the scanner firmly. The error clears once the cradle reads a clean voltage signal — typically within a few seconds of firm contact.

Scanner dropping wireless connection during rapid scan bursts

The QC150 and QC200 pull current simultaneously from the wireless radio and the scan trigger on every burst. A degraded or partially charged cell sags in voltage under that combined load, briefly dropping below the radio module's minimum supply threshold and causing a connection drop. This is not a wireless or firmware problem — it is a voltage sag event at the cell level. Charge the pack fully before the shift and check that the cell voltage reads at or above 5.0V off the cradle before logging the scanner into the network.
