Motorola MC3200 Barcode Scanner Replacement Battery 3.7V 4800mAh

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

This is a 3.7V, 4800mAh Li-ion battery for the Motorola MC3200, MC32N0, and MC32N0-S handheld mobile computers. It cross-references OEM part numbers BTRY-MC32-01-01, 82-000012-01, BTRY-MC33-52MA-01, and BTRY-MC32-52MA-10. These scanners run in retail, warehouse, and logistics environments where a dead battery mid-shift stops data capture entirely.

• MC3200 / MC32N0 / MC32N0-S fit: All three model variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. Swapping across these variants requires no adapter — the pack seats and communicates identically across the series.
• Bench tested on actual hardware: We ran this pack on an MC32N0-S unit and cycled the BMS through charge, discharge, and low-voltage cutoff sequences. The protection circuit responded correctly at both ends of the voltage window, with no false cutoff events during simulated scan-burst draws.
• First-shift prep for MC3200 units: After installing this pack, seat the scanner in its cradle and allow a full charge cycle before deploying it on the floor. The scan trigger inrush current is highest when the cell is near minimum charge, and a fully pre-charged pack prevents false BMS trips during the first wave of pick-and-pack scanning.

Cradle showing a charging error on a new pack

The MC3200 charging cradle reads pack status through pogo-pin contacts on the battery base. If those contacts carry any oxidation, skin oil, or warehouse dust, the cradle sees elevated resistance and flags a charging fault rather than starting the charge cycle. This is not a faulty battery — it is a contact issue. Wipe the gold contacts on both the battery and the cradle slot with a dry lint-free cloth, reseat the pack firmly, and the charging indicator should switch to active within 15 seconds.

Scanner losing wireless connection during rapid scan bursts

During a fast scan burst, the MC32N0 draws current simultaneously from the imager, the processor, and the 802.11 radio. On a depleted or degraded cell, that combined inrush can pull the cell voltage below the BMS trip threshold for a fraction of a second, causing the radio stack to drop association. The scanner may continue scanning locally but stops syncing data to the host until the connection re-establishes. If this happens repeatedly, charge the pack to at least 3.9V before the shift and confirm the wireless polling interval in your MDM profile is not set below 100ms.
