Before lithium batteries, we had alkaline. The worst thing you could do was to "wear out" the alkaline battery from an incorrect charging cycle. Li-on batteries can catch fire from improper charging, and burn your home or office down. Oh well.

As I read about li-on batteries, two factors are important to prevent battery health problems.
First, temperature.
Second, cycles of charging.
The best option for a laptop user is to connect the laptop to adapter while using it. But if you that, it will charge your device until battery reaches 100%. This will put battery under pressure. The best option is to limit battery charge to about 50~70 percent. So when you connect laptop to charger, it will charge battery until it reaches 70%. After that your device will use the adapter. This will increase your battery lifetime.

This isn't a question of how smart you are. OEM's consider this proprietary technology, and won't share it.

You could be a really bored open-source hacker who wants to reverse-engineer the API's, but don't expect them to unlock every PC out there for you. It's a lot of individual work.
