Battery warranty is one of the more grey areas of warranty coverage. Depending on local legislation and the specific coverage for the model you can get 6-12 months (it's considered a consumable) and the warranty might start when the battery was manufactured rather than the sale date (like Dell did some years ago, not sure if it's still a practice).

Consumables are readily replaced at low cost. Batteries (in phones/tablets) are essential central components.

If you need tools or instructions then the parts aren't really consumables.

Part of the issue is the trend of integrating parts that used to be easily replaceable. My first phone/laptop each had batteries that could be swapped in under 10 seconds with no tools. My latest do not.

Whole device is a consumable. Six months of usage and off to a landfill it goes.

In my experience it's always tagged to the device at time of sale like any other warranty. Usually this comes into play if the device and the battery somehow have different warrantie.

However I am hardly an expert on this. I can speak to the surface though (we use them at work) and most definitely is covered
