Questions about this item

Will the HSTNN-LB7L fit inside my HP Spectre x360 13-w031ng without any case modification?

Yes, the HSTNN-LB7L is a direct replacement for part numbers SH03XL, 859026-421, 901308-421 and 859356-855, which are the original batteries for the Spectre x360 13-w031ng and the 13-w0XX series.

What is the step people often miss when installing this 11.55 V lithium-polymer pack in a Spectre x360 13-ac033dx?

After removing the bottom cover, disconnect the old battery connector from the motherboard before unscrewing the pack; skipping that disconnect risks a short circuit on the 11.55 V rail.

How many full charge cycles can I expect from the 57.9 Wh HSTNN-LB7L before it needs replacing?

The manufacturer highlights high recycle life and long life for this lithium-polymer cell, but does not publish a specific cycle-count rating.
