Questions about this item

Does this 3-cell 11.1 V 31 Wh battery fit the HP 250 G3 laptop I already own?

Yes, the 250 G3 appears in the compatible models list so the battery is designed to fit that chassis.

Will this replacement work in a machine that originally used an HSTNN-LB5S pack?

The HSTNN-LB5S part number is listed among the compatible part numbers, so the battery is a direct replacement for that pack.

After installing the battery, how can I confirm it is delivering the rated 11.1 V and 31 Wh?

Check the BIOS or operating system power report; it should show an 11.1 V design voltage and a 31 Wh design capacity for the new pack.
