About this replacement
Zebra MC2200 / MC2700 — 3.85V Li-ion Replacement Battery (BT-000409)
This 3.85V, 3300mAh Li-ion battery replaces the OEM pack in the Zebra MC2200 and MC2700 mobile computers. Both are handheld barcode scanners used in warehouse, retail, and logistics environments where the device runs through full scan shifts without returning to a workstation. Swap out a degraded pack and the scanner is back in rotation the same shift.
- MC2200 and MC2700 shared battery platform: Both models run the same 3.85V battery rail, use the same physical connector, and communicate with the same BMS handshake over the pack's data line. One replacement battery covers both devices without any modification.
- Bench tested on actual hardware: We cycled this pack through the MC2200's charge dock and confirmed the BMS handshake completed correctly. The dock accepted the pack without a fault LED, and the protection circuit responded to both overcharge and deep-discharge cutoff thresholds as expected.
- First-shift preparation for pick-and-pack operations: After installing a new pack, place the scanner in its cradle for a full charge cycle before deploying it. The scan trigger inrush current is highest when the cell voltage is near minimum, and a fully charged cell prevents false BMS trips during the first high-frequency scan burst of the shift.
Cradle showing a charging error on a new pack
The MC2200 charging cradle communicates with the battery's BMS through the contact array on the base of the device. If those contacts have oxidation, debris from a warehouse floor, or residue from a previous pack, the dock reads a handshake fault and throws a charging error LED. This is not a faulty battery — it is a contact resistance issue. Wipe the gold contacts on the pack and the cradle pins with a dry cloth, reseat the scanner firmly, and the dock should clear the error and begin charging within 30 seconds.
Scanner losing wireless connection during rapid scan bursts
During a fast scan burst, the MC2200 draws current simultaneously from the imager, the wireless radio, and the processor — combined inrush that spikes well above the steady-state draw. If the cell voltage has sagged from age or partial charge, the BMS can momentarily throttle output, which causes the wireless radio to drop before the imager does. The result looks like a connectivity fault but is actually a low-voltage brown-out at the radio subsystem. Charge the pack to full before the shift and verify the cradle contact is clean — a fully charged cell at 4.2V holds the voltage rail through burst events that a depleted or degraded cell cannot.
