#How does Windows detect battery issues?

How does Windows detect battery issues?

I have a laptop that's a little over 5 years old, and I've never changed the battery, so I believe Windows 7 when it tells me "there is a problem with your battery", and to consider replacing it.

My question is: how does it detect a dodgy battery? Does the battery not have the same voltage that it used to?

I think this is an interesting question, and could form the basis for a blog post with some more detail about how battery technology works and why batteries degrade over time, or perhaps more detail about ACPI and how it works.
