BTRY-MC32-01-01 Motorola MC3200 Barcode Scanner Replacement Battery 3.7V 2500mAh

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

This 3.7V 2500mAh Li-ion battery fits the Motorola MC3200, MC32N0, and MC32N0-S mobile computers — rugged handheld devices used in retail, warehouse, and logistics environments. It matches OEM part numbers BTRY-MC32-01-01, 82-000012-01, BTRY-MC33-52MA-01, and BTRY-MC32-52MA-10. The cell and BMS are spec-matched to the MC3200 platform so the device firmware reads state-of-charge correctly.

• MC3200, MC32N0, and MC32N0-S fit: All three variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. A single pack covers the full MC32 hardware generation without modification.
• Bench tested on actual hardware: We ran this pack on an MC32N0-S under combined wireless polling and rapid scan trigger cycles. The BMS held voltage above the device's 3.2V cutoff threshold throughout the test and reported accurate charge percentage to the OS.
• First-shift prep on pick-and-pack lines: Install the battery and place the scanner in its cradle for a full charge cycle before the shift starts. Scan trigger inrush is highest when the cell is near minimum voltage — a fully charged cell prevents false BMS trips the first time a picker pulls the trigger.

Cradle charging error on a freshly installed pack

The MC3200 four-slot cradle uses spring-loaded contacts that transfer both charge current and communication data to the battery BMS. If those contacts have oxidation or debris, the cradle throws a charging fault even though the pack itself is fine. The cradle firmware interprets high contact resistance as a pack error, not a dock error, so the scanner shows a red charge indicator. Wipe the gold contacts on both the battery and the cradle slot with a dry lint-free cloth, reseat the scanner firmly, and the charging indicator should switch to amber within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

The MC32N0 draws simultaneously from the 802.11 radio and the scan trigger during high-frequency scan bursts — two inrush loads hitting the cell at the same time. If the battery voltage sags below roughly 3.4V under that combined load, the radio stack drops its association before the device can reconnect automatically. This shows up as a momentary disconnect on the host WMS, not as a scanner error. Charge the battery above 50% before high-throughput receiving sessions to keep cell voltage in the range where sag stays within the radio's tolerance.
