Replacement 14.4 V 5200 mAh battery

This KingSener SQU-1406 unit is a new lithium-ion replacement battery rated at 14.4 V and 5200 mAh (74.88 Wh). It uses high-quality cells and a matching PCB to deliver full design capacity and stable runtime. The physical size matches the original battery so installation requires no modification. It is built for compatible ThundeRobot and iBUYPOWER Chimera laptops.

Suited for owners of listed ThundeRobot

Buyers whose original battery carries the SQU-1406 part number will find a direct fit. Users of other ThundeRobot series or different laptop brands should look elsewhere because the connector and case profile will not match. Anyone needing a higher capacity than 5200 mAh or a different voltage must choose another part.

Voltage and capacity determine compatibility

The battery operates at 14.4 V and stores 5200 mAh (74.88 Wh); both values must equal the original specification for safe operation. If the original battery shows a different voltage or capacity this unit will not work correctly.
