Motorola MC3200 Replacement Battery BTRY-MC32-01-01 3.7V 6800mAh

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

This is a 3.7V Li-ion battery rated at 6800mAh (25.16Wh), built to fit the Motorola MC3200, MC32N0, and MC32N0-S handheld barcode scanners. These units run in retail stockrooms, distribution centres, and logistics operations where scanners stay active across full shifts. The cell matches the original pack dimensions at 80.10 x 45.72 x 22.80mm and seats into the battery bay without modification.

• MC3200 and MC32N0 platform fit: The MC3200 and MC32N0-S share the same battery bay dimensions, connector pinout, and BMS communication protocol. One pack covers all three variants because Motorola used a common power rail across this scanner generation — swapping between units does not require reconfiguration.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on an MC32N0, monitoring the BMS handshake with the cradle and the voltage curve under combined scan-trigger and wireless radio load. The BMS accepted the charge signal from the cradle on first insertion and held stable voltage through repeated scan bursts without tripping a low-voltage cutoff.
• First-shift preparation for MC3200 scanners: After installing the new pack, place the scanner in its cradle for a full charge cycle before pulling it into active picking. The scan-trigger inrush current is highest when the cell is near minimum charge — a pre-charged cell prevents false BMS cutoffs during the first hours of use on the floor.

Cradle showing a charging error on a new pack

The MC3200 cradle communicates with the battery through five contact points on the underside of the pack. Oxidation or debris on even one contact pin raises resistance enough for the cradle to report a fault rather than begin charging. This is not a faulty battery — it is a contact issue. Remove the pack, wipe the gold contacts on both the battery and the cradle slot with a dry cloth, reseat firmly, and the charging LED should switch to amber within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan sequence, the MC32N0 pulls current simultaneously from the imager and the 802.11 radio. If the cell voltage sags below approximately 3.4V under that combined load, the BMS briefly throttles output to protect the cell, and the radio drops its association before the scanner recovers. This happens most often with a partially depleted pack during a high-frequency pick run. Return the scanner to the cradle until the indicator shows at least a two-bar charge before continuing high-volume scanning.
