Questions about this item

How do I confirm the 10.8V 5200mAh battery is charging correctly after installing it in my ThinkPad?

The laptop's power manager should show the cell charging toward 5200mAh and report a stable 10.8V output; the built-in over-temperature and short-circuit protection will prevent unsafe operation.

What comes in the box with the sE430 battery and do I need any extra parts for installation?

The package contains the 6-cell Li-ion battery only; no tools or cables are included, and the unit fits directly into the existing battery bay of compatible ThinkPad models.

Which part number should I match to ensure the sE430 fits my specific ThinkPad model?

Match your original battery's part number against the listed compatibles such as 45N1042, 45N1043, 45N1048, 45N1049 or 45N1055 to confirm fit.
