Questions about this item

Will this battery fit inside my ThinkPad T470 without any case modification?

The battery measures 8.0 by 1.5 by 0.8 and weighs 0.4, matching the original internal dimensions so it installs without modification.

Does the 11.4 V output match the voltage my ThinkPad T480 expects from the original pack?

Yes, the 11.4 V rating is identical to the factory specification for the T480, so the system recognises it and charges normally.

How can I confirm the new pack is reporting the correct capacity after I install it?

In Windows, open the battery report or Lenovo Vantage; both should show a design capacity of 4400 mAh and a voltage of 11.4 V for this pack.
