Zebra MC3200 Compatible Battery BTRY-MC32-01-01 3.7V 6800mAh

Zebra MC3200 / MC32N0 Series — 3.7V Li-ion Replacement Battery (BTRY-MC32-01-01)

This is a 3.7V 6800mAh Li-ion battery for the Zebra MC3200, MC32N0, and MC32N0-S mobile computers. It replaces OEM part numbers BTRY-MC32-01-01, BTRY-MC32-52MA-01, BTRY-MC33-52MA-01, BTRY-MC32-52MA-10, BTRY-MC33-27MA, and BT-000375. The pack fits the standard battery bay and connects to the BMS handshake the MC3200 expects before enabling the scan trigger.

• MC3200 / MC32N0 / MC32N0-S compatibility: All three models share the same 3.7V battery rail, physical bay dimensions, and five-pin BMS connector. The host device authenticates the pack before activating the imager and radio — this replacement carries the correct cell chemistry identification to pass that handshake without a boot error.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on an MC32N0 unit. The BMS reported state-of-charge correctly to the device OS, the scan trigger fired cleanly from a cold start, and the wireless radio held association through sustained scan bursts without voltage sag tripping an undervoltage fault.
• First-shift cradle protocol: After installing this pack, seat the scanner in its charging cradle for a full charge cycle before taking it onto the floor. The scan trigger draws the highest inrush current when the cell is near minimum — a fully charged cell prevents false BMS trips during the first pick-and-pack shift of the day.

Cradle showing a charging error on a new pack

MC3200 charging cradles communicate with the battery pack through spring-loaded dock contacts. If those contacts accumulate dust, oxidation, or label residue during shipping, the cradle cannot complete the charge circuit and throws an error LED. Remove the pack, wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat firmly. The cradle should begin charge within 10 seconds and the LED should shift from amber to solid green.

Scanner losing wireless connection during a rapid scan burst

The MC32N0 fires the imager and transmits the decoded barcode over Wi-Fi in near-simultaneous draws — combined inrush can spike current demand sharply inside a sustained burst. If the cell voltage sags below the BMS cutoff threshold at that instant, the radio drops its association before the imager even reports a failed read. This usually presents as the scanner appearing to read successfully but the WMS receiving no data. Charge the pack to full before shift start and check that the cradle contact voltage reads at least 4.15V per cell with a multimeter before deploying.
