Compatible Anritsu battery

The Cameron Sino Qube 91390 is a 7800mAh 11.1V replacement battery built for a wide range of Anritsu instruments, including the MS2024A, MS2025B, MS2026C, MS2711E, MS2721A, MT8212E and S331E series. It matches original part numbers such as 146-0142-00, GPDR204, NI2040 and LI204SX-66A, so technicians can swap the pack without hunting for a discontinued OEM unit. The fully decoded chip communicates with the host device exactly like the factory cell.

Upgrading from a depleted pack

This unit replaces an exhausted original battery that no longer holds sufficient charge for field measurements. The jump is worth it when the instrument shuts down mid-session or fails to power on away from mains supply. A fresh 86.58Wh cell restores the full mobile runtime the analyser was designed for, avoiding the cost and delay of sending the whole unit back to the manufacturer for service.

Sustained field operation

Under continuous load the 7800mAh capacity delivers steady voltage across the discharge curve, keeping the analyser stable during long cable sweeps or spectrum captures. The pack measures 213.11 x 58.51 x 22.22mm and weighs 465.0g, fitting the original bay without modification. ISO9001, RoHS and CE certification confirms consistent cell quality for repeated daily cycles in demanding environments.

Questions about this item

What are the exact dimensions of the Qube 91390 battery pack so I can confirm it fits my Anritsu MS2026A?

The battery pack measures 213.11 x 58.51 x 22.22 mm, matching the original Anritsu 146-0142-00 form factor.

How do I install this 11.1V battery in my MS2721B, and what is the most common mistake?

Align the connector with the device port and press firmly until it clicks; the step most often missed is fully seating the connector before closing the battery door.

When will the 7800mAh capacity need replacement, and what is the first maintenance step?

After 2 or 3 full charge and discharge cycles the pack reaches peak performance; plan replacement when runtime drops below your clinical requirements.
