Questions about this item

Does the 4-cell 33 Wh battery fit the HP 17-G121WM chassis?

Yes, it replaces part numbers 800049-001, K104, 800010-421, KI04, KIO4, HSTNN-LB6R, HSTNN-DB6T and HSTNN-LB6S used in that model.

What is the step people miss when installing the 14.8 V lithium-ion pack?

After seating the battery, lock both release latches fully; a loose latch breaks contact and the laptop will not power on.

Replace it once run-time falls well below the original 33 Wh rating or the battery no longer holds a full charge.
