Motorola 3 Model C Barcode Scanner Compatible Battery 3.7V 2000mAh

Motorola WorkAbout Pro 4 / 3 Model C Series — 3.7V Li-ion Replacement Battery

This 3.7V, 2000mAh (7.4Wh) Li-ion cell replaces the factory battery in Motorola handheld barcode scanners including the 3 Model C, 3 Model S, WorkAbout Pro 4, and WorkAbout Pro G1. It fits the same battery bay and connects to the same BMS handshake as the original pack. Use it in retail, warehouse, or logistics environments where scanner downtime cuts directly into pick rates.

• Multi-model fit — 3 Model C, 3 Model S, WorkAbout Pro 4, WorkAbout Pro G1: These scanners share the same 3.7V single-cell architecture, battery bay footprint, and BMS communication protocol — which is why one pack covers all of them without modification or adapter.
• Bench tested on actual hardware: We cycled this pack under combined scan-trigger and wireless radio load. The BMS held voltage above the low-cutoff threshold through burst scanning sequences and recovered cleanly between cycles without false trips.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before sending it to the floor. Scan-trigger inrush current peaks when the cell is near minimum charge — a fully charged pack prevents BMS trips on the first heavy pick run of the shift.

Cradle showing a charging error on a new pack

Motorola's charging cradles use contact-resistance sensing to confirm a valid pack is seated before starting a charge cycle. Oxidation or dust on the battery's gold contacts raises that resistance above the cradle's threshold, triggering an error state even though the pack itself is fine. Remove the battery, wipe all contacts — both on the pack and inside the cradle — with a dry lint-free cloth, then reseat firmly. If the error clears, the pack charges normally from that point.

Scanner dropping wireless connection during rapid scan bursts

Fast barcode scanning and active wireless radio polling draw simultaneously, creating brief combined inrush spikes that can pull cell voltage below the BMS's minimum threshold. When that happens, the BMS cuts power momentarily — the scanner drops its wireless session before recovering. This is more pronounced when the cell is below 50% charge. Keep the pack above that level during high-frequency scan runs, and charge during any break longer than ten minutes to stay above the 3.5V sag threshold.
