M3 Mobile eTicket MCB-6000S Replacement Battery 3.7V 3200mAh

M3 Mobile eTicket / UL10 Series — 3.7V Li-ion Replacement Battery (MCB-6000S)

This 3.7V, 3200mAh Li-ion cell replaces the original battery in M3 Mobile eTicket, Rugged, UL10, and MC-7700S handheld scanners. It fits the same form factor and connector as the OEM pack (MCB-6000S / HSM3-2000-Li). Capacity figure is taken directly from product data — 11.84Wh.

• eTicket and UL10 platform fit: These models share the same battery bay dimensions, 3.7V single-cell architecture, and BMS handshake protocol. One SKU covers the group because the connector pinout and charge termination logic are identical across the platform.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a UL10 unit. The BMS accepted the cell without error flags, terminated charge correctly at 4.2V, and held cutoff voltage within spec under sustained scan-and-transmit load.
• First-shift cradle protocol: After installing, seat the scanner in its cradle and run a full charge cycle before pulling it into service. Scan trigger inrush current peaks when the cell sits near minimum — a pre-charged pack prevents false BMS trips during the first burst of the shift.

Cradle showing a charging error on a new pack

A fresh Li-ion cell shipped at storage charge (around 3.6–3.7V) can trigger dock-side charging errors if the cradle contacts are dirty or the pack is not fully seated. The cradle reads contact resistance to confirm a valid pack; anything above threshold trips an error rather than starting the charge cycle. Wipe the gold contacts on both the pack and the cradle with a dry cloth, then reseat the scanner firmly until it clicks. The error should clear and charging should begin within 15 seconds.

Scanner losing wireless connection during rapid scan bursts

During a fast scan burst the eTicket draws simultaneously from the imager and the wireless radio — two inrush loads hitting the cell at the same time. If the cell voltage sags below the radio's minimum operating threshold, the wireless stack drops the connection before the scanner logs an error. This is more common when the battery is below 20% charge. Keep the pack above that threshold during high-frequency pick operations, or swap to a charged unit before the shift hits that floor.
