Zebra MT2000 Replacement Battery 3.7V 2400mAh

Zebra MT2070 / MT2090 Series — 3.7V Li-ion Replacement Battery (82-108066-1)

This is a 3.7V 2400mAh Li-ion battery for the Zebra MT2000, MT2070, MT2090, and RFD5500 handheld mobile computers. These scanners are used in pick-and-pack, receiving, and retail stock operations where the unit runs through multiple shifts. When the original cell degrades, scan trigger response slows and wireless drops become frequent — this pack restores normal operation.

• MT2000 / MT2070 / MT2090 / RFD5500 fit: All four models share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. The MT2070 and MT2090 are variants of the same platform — the cell communicates state-of-charge to the device over the same data line, so the fuel gauge reads correctly on all four.
• Bench tested on actual hardware: We cycled this pack through scan-burst and wireless-active load profiles on the MT2070. The BMS held stable across inrush from the laser trigger combined with active 802.11 polling, and the cell did not trip the low-voltage cutoff during simulated high-frequency scan sequences.
• First-shift prep for pick-and-pack use: After installing, seat the scanner in its cradle and let it complete a full charge cycle before using it on the floor. Scan trigger inrush is highest when the cell is near minimum — a fully charged pack prevents false BMS trips during the first shift's high-demand opening period.

Cradle showing charging error on a new pack

The MT2000-series cradle checks contact resistance before initiating the charge cycle. If the gold contacts on the battery base or the cradle pins have oxidation or debris, the cradle flags a fault and stops charging before current flows. Wipe the battery contacts and cradle pins with a dry cloth, then reseat the pack firmly until it clicks. If the error clears, the contact surface was the problem — not the cell or the cradle electronics.

Scanner losing wireless connection during rapid scan bursts

The MT2070 and MT2090 draw current simultaneously from the scan trigger and the 802.11 radio during rapid barcode capture sequences. A degraded or deeply discharged cell cannot sustain that combined inrush, and the voltage sags enough to drop the radio connection. The BMS does not trip — the radio simply loses its minimum operating voltage for a fraction of a second. Charge the replacement pack fully before the shift and the combined draw stays well within the cell's sustained current rating.
