M3 Mobile Smart Barcode Scanner Replacement Battery 3.7V 2000mAh

M3 Mobile Smart / ST10 — 3.7V Li-ion Replacement Battery (A-BAT-STD0-080-R00)

This is a 3.7V 2000mAh Li-ion battery for the M3 Mobile Smart and ST10 handheld barcode scanners. It replaces OEM part numbers A-BAT-STD0-080-R00, ST10-BATT-S22, and B056H013-0001. The Smart and ST10 are compact scanners used in retail, warehouse, and logistics environments where batteries cycle hard across multi-shift operations.

• Smart and ST10 compatibility: Both models share the same 3.7V battery bay, connector pinout, and BMS communication protocol — one pack covers both platforms without modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the ST10, confirmed BMS handshake with the cradle charging circuit, and verified the protection circuit tripped correctly at the low-voltage cutoff threshold.
• First-shift preparation: After installing a new pack, seat the scanner in its cradle and complete a full charge cycle before using it on the floor. The scan trigger inrush current peaks when the cell is near minimum charge, and a pre-charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new pack

The Smart cradle monitors contact resistance between the dock pins and the battery terminals. A new pack with any residue or slight misalignment on the gold contacts can read as a fault rather than a low-charge state. The dock interprets high contact resistance as a pack error and refuses to initiate the charge cycle. Wipe the battery terminals and cradle contacts with a dry cloth, reseat the scanner firmly until it clicks, and the charging indicator should switch from error to active within 10 seconds.

Scanner losing wireless connection during rapid scan bursts

On the ST10, the wireless radio and scan trigger draw current simultaneously during a fast scan burst — the combined inrush can cause a momentary voltage sag on a partially depleted cell. When cell voltage dips below the radio module's minimum operating threshold, the wireless stack drops and has to re-associate with the access point. This appears as a disconnection or "offline" status on the host system mid-scan session. Keeping the pack above 40% state of charge during high-frequency scanning eliminates the sag — charge the pack when the battery indicator hits two bars.
