Replacement battery for ThundeRobot 911 series

This 14.4V lithium-polymer pack delivers 74.88Wh and 5200mAh for ThundeRobot 911-E1 911-T2A 911-S2B 911-T1 911M Series notebooks. It arrives new and ready for plug-and-play installation. The black housing matches the original form factor.

Verification required before purchase

Buyers must open the laptop and confirm the original battery part number is SQU-1406; the connector layout shown in the product images must also match. Builders working on other ThundeRobot models or different brands should look elsewhere. Anyone unwilling to remove the bottom case for verification cannot use this part safely.

14.4V 74.88Wh capacity specification

The single decisive figure is the 14.4V 74.88Wh rating; the replacement will only work correctly if the original battery carries the same voltage and watt-hour value. A different voltage or capacity will cause charging errors or reduced runtime. No other specification overrides this requirement.

Questions about this item

How can I verify the SQU-1406 battery is working correctly after installation?

After fitting the battery, discharge it to 5% then charge to 95% and repeat this cycle three to four times. This conditions the 74.88Wh cell and confirms normal charge reporting.

What comes in the box with the SQU-1406 and what must I source separately?

The package includes one SQU-1406 battery only. No tools, screws or adapters are supplied, so have a suitable screwdriver ready to open the laptop case.

Which version of the SQU-1406 should I choose for my ThundeRobot 911-E1 or 911M series notebook?

There is a single 14.4V 5200mAh version. Match the SQU-1406 part number printed on your original battery before ordering to ensure compatibility.
