Questions about this item

Does the GreenTech RU03XL battery ship with any installation tools or screws, or must I buy them separately?

The package contains only the 3-cell lithium-ion battery itself; no tools, screws or adapters are included.

My ProBook X360 440 G1 uses part number L12791-855 — is this the exact match or do I need a different capacity?

This unit is listed as compatible with L12791-855 and delivers 11.4 V, 48 Wh and 4210 mAh, matching the original specification.

What does the 48 Wh rating mean for daily runtime on an X360 11 G4?

At 48 Wh the pack stores the same energy as the factory battery, so typical mixed-use runtime will be equivalent to when the laptop was new.
