Datalogic QuickScan Mobile 2130 Replacement Battery 3.7V 750mAh

Datalogic QuickScan Mobile 2130 — 3.7V Li-ion Replacement Battery (90ACC1945)

This 3.7V 750mAh Li-ion cell replaces the factory battery in the Datalogic QuickScan Mobile 2130, M2130, and QM2130 handheld barcode scanners. It matches the OEM part numbers 90ACC1945, 128000791, 128000790, and BT-7. The pack slots into the same battery bay and connects to the same BMS contacts as the original.

• QM2130 platform fit: The M2130, QM2130, and QuickScan Mobile variants share a common battery bay, connector pinout, and BMS handshake protocol. One pack covers all of them — no adapter or firmware change needed.
• Bench tested on actual hardware: We ran this pack through scan-burst cycles on a QM2130 unit. The BMS held voltage above the 3.0V cutoff floor through sustained trigger pulls and active wireless polling without tripping into protective shutdown.
• First shift prep for pick-and-pack use: After installing, seat the scanner in its charging cradle and run a full charge cycle before the first shift. Scan trigger inrush current spikes hardest when the cell is near its minimum charge level — a fully charged pack prevents false BMS trips during the first high-frequency scanning session.

Cradle showing charging error on a new pack

A charging error on the dock with a fresh pack almost always comes down to contact resistance at the battery terminals. Dock contacts and pack contacts both accumulate oxidation and debris from warehouse handling. Wipe the gold contacts on the pack and the cradle pins with a dry cloth before reseating. Once contact resistance drops, the dock handshake completes and charging begins normally at 4.2V target.

Scanner dropping wireless connection during rapid scan bursts

The QM2130 draws simultaneously from the radio module and the scan trigger during rapid burst scanning — two inrush events layered on top of each other. If the cell voltage sags below the radio module's minimum operating threshold mid-burst, the wireless stack drops the connection before the BMS trips. This is most common when the battery is below 30% charge. Keep the pack above half charge during high-frequency scanning shifts to keep the combined draw within the cell's output headroom.
