Zebra Omnii XT15 Replacement Battery 3.7V 5200mAh

Zebra Omnii XT15 / 7545XT Series — 3.7V Li-ion Replacement Battery (1110108)

This 3.7V, 5200mAh Li-ion cell replaces the OEM pack in the Zebra Omnii XT15 and 7545XT rugged handheld computers. It fits the full XT15 and 7545MBW line that shares the same battery bay and connector pinout. Capacity matches the original 19.24Wh rating from the product data — not an inflated third-party figure.

• XT15 and 7545 platform fit: These models share one battery form factor, connector, and BMS communication protocol. The same latch, contact rail, and pack geometry carry across the XT15, 7545MBW, and 7545XT — one replacement covers the whole fleet.
• Bench tested on actual hardware: We cycled this pack through scan-trigger inrush and sustained wireless polling loads. The BMS held charge delivery through repeated imager activation bursts without tripping the overcurrent cutoff.
• First-shift cradle charge: After installing, seat the scanner in its cradle for a full charge cycle before putting it on the pick-and-pack floor. Scan-trigger inrush is highest when the cell sits near minimum — a fully charged cell prevents false BMS trips that can look like a faulty battery on the first shift.

Cradle showing charging error on a new pack

Cradle charging errors on a fresh pack almost always come down to contact resistance at the dock, not a fault inside the battery. Dust, warehouse grime, or oxidation on the gold contacts breaks the data line the cradle uses to verify the pack. Wipe the battery contacts and cradle contacts with a dry cloth, then reseat firmly until the latch clicks. If the error clears within 30 seconds, the pack is communicating — charge can begin and the error was contact-related, not a dead cell.

Scanner dropping wireless connection during rapid scan bursts

When the imager fires and the radio is polling simultaneously, combined inrush can pull the cell voltage below the radio module's minimum operating threshold for a fraction of a second — enough to drop the wireless session. This happens most with a partially degraded pack, but can also appear with a new battery that shipped partially discharged. Charge the pack to full before the shift starts. If disconnects persist on a fully charged cell, check that the contact rail is seated flush — a partial contact increases internal resistance and worsens voltage sag under combined load.
