Questions about this item

What HP laptop series must I own for the JC03 31Wh battery to fit?

The JC03 fits HP Notebook 15-bs, 15-bw, 17-bs, 15q-bu, 15g-br, 17-ak and 15q-by series including models such as 15-bs013dx, 15-bw033wm and 17-bs011dx.

Will the 10.95V 3-cell JC03 work in a notebook that originally used a 4-cell HSTNN-LB7W pack?

Yes, the JC03 replaces part numbers HSTNN-LB7W, HSTNN-LB7V, HSTNN-DB8E and HSTNN-PB6Y, so it works in place of the original 4-cell pack.

How can I verify the JC03 is charging correctly after installation?

The battery management circuit reports the 10.95V 31Wh capacity to the BIOS; a full charge should show roughly 2600mAh and the OS battery health tool will read the cycle count starting from zero.
