Questions about this item

Does the FOCUSTEC LK03XL battery ship with any installation tools or screws?

The battery is supplied as a standalone 3-cell lithium-polymer pack; no screwdrivers, screws or adhesive strips are included.

My Envy 17-AE143NG and Envy X360 15-BP107TX both appear in the compatibility list — do they use the same 11.55 V 52.5 Wh pack?

Yes, both models are listed for the identical 11.55 V 52.5 Wh LK03XL unit, so one battery fits either machine.

What does the 52.5 Wh rating translate to for daily runtime on an Envy 15-BP000?

The 52.5 Wh capacity typically delivers several hours of mixed use on an Envy 15-BP000; actual time varies with screen brightness, workload and power settings.
