Questions about this item

Does the G3HTA057H battery come with any tools or adhesive strips, or must I buy them separately?

The package contains only the 6-cell 7.58 V 6041 mAh battery with its long cable; no screwdrivers, pry tools or adhesive strips are included, so you will need to source those separately.

My Surface Laptop 4 15 is model 1873 — is this the correct GreenTech replacement?

Yes, the G3HTA057H is listed as compatible with Microsoft Surface Laptop 15 1873 as well as the 1872 variant and both Intel and AMD versions of the 15-inch Laptop 3 and 4.

What does the 45.8 Wh rating mean for daily runtime once the battery is installed?

The 45.8 Wh capacity matches the original specification, so you can expect comparable run time to a factory-fresh unit — typically several hours of mixed office work depending on screen brightness and workload.
