M3 Mobile Orange OX10-BATT-S33 3.7V 3300mAh Compatible Battery

M3 Mobile Orange / OX10 Series — 3.7V Li-ion Replacement Battery (OX10-BATT-S33)

This is a 3.7V, 3300mAh Li-ion replacement for the M3 Mobile Orange and OX10 series handheld barcode scanners, including the OX10 RFID variant. It matches the OEM part number OX10-BATT-S33 and fits the same battery bay without modification. Capacity is 3300mAh (12.21Wh) — drawn from the product specification, not estimated.

• Orange, OX10, and OX10 RFID compatibility: All three models share the same 3.7V battery bay, connector pinout, and BMS communication protocol. A single cell covers the full range — the RFID variant adds antenna draw but runs on the same voltage rail.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an OX10-class unit. The BMS accepted the pack without fault codes, and the protection circuit responded correctly to overcurrent and over-discharge thresholds.
• First-shift preparation for pick-and-pack: After installing, seat the scanner in its cradle and complete one full charge cycle before sending it to the floor. The scan trigger draws the highest inrush current when the cell is near minimum — a fully charged pack prevents false BMS trips during the first burst-scan sequence of the shift.

Cradle showing a charging error on a new pack

Charging docks on the OX10 series are sensitive to contact resistance between the battery terminals and the cradle pins. A new pack with any film, oxidation, or residue on the gold contacts can trigger a dock fault before charging even starts. Wipe the battery contacts and the cradle pins with a dry lint-free cloth, then reseat the scanner firmly until you hear the click. The dock should clear the error and show the charging indicator within 10 seconds.

Scanner dropping wireless connection during rapid scan bursts

The OX10 combines simultaneous radio polling and scan-trigger inrush — both draw from the same cell at the same moment during a burst scan. If cell voltage sags below the radio module's minimum threshold during that combined load, the wireless stack resets while the scanner stays on, which looks like a dropped connection rather than a power fault. This is most common on a partially depleted cell mid-shift. Check cell voltage under load — if it drops below 3.4V during a scan burst, the cell needs replacement or the pack needs a full recharge before continuing.
