Replacement battery for TST-902 models

This lithium-polymer pack is built as a direct replacement for devices using the TST-902 designation. It suits owners of compatible laptops who need to restore original run-time without modifying the chassis. Buyers who cannot confirm both the model and part number should not purchase.

3.7 V 10000 mAh lithium-polymer cell

The single specification that decides fit is the 3.7 V 10000 mAh rating, which equals 37.00 Wh of stored energy. Matching this voltage and capacity to the original battery ensures the power-management firmware reports charge levels correctly. A different voltage or capacity will cause inaccurate readings or prevent boot.

No bundled accessories or software included

The package contains only the battery itself; no tools, cables, drivers or management utilities are supplied. Installers must reuse existing screws and connectors from the old pack. Users who expect a screwdriver kit or calibration software will need to source those separately.
