Questions about this item

How much heat does the 79.2W lithium-ion pack generate during all-day use?

Lithium-ion cells run cool under normal load; the 6-cell design spreads discharge evenly so the battery stays at safe temperatures during extended sessions.

What must my laptop already have for this 11.55V battery to work?

Your Spectre x360 must be one of the listed models — 15-BL100NC, 15-BL104NB, 15-BL000UR, 15-BL010CA or 15-BL101UR — and use the original 11.55V connector.

Will the 6-cell pack fit the same bay as the original battery in my 15-BL100NC?

Yes, the replacement matches the factory dimensions and locking points, so it seats securely without modification.
