Mini laptop battery question

"Generally yes, I'd use the power source instead of the battery when available.

But keep in mind...

A battery should not be left charged in a dormant state for a very long time. After it is fully charged you should use it at least once every few weeks at a bare minimum to extend battery life. If you are using an older lithium-ion battery, avoid letting its charge drop to 0. Lithium-ion batteries typically have what is called a discharge/charge cycle of 300-500.

You shuould.Avoid allowing the battery to drop below 5% of capacity because most new versions of the Windows OS will automatically put your laptop computer in a forced “hibernation” mode which may cause the loss of some projects you are working on.Only remove or install a laptop battery when your computer is turned off, this will avoid any current surge that could harm your new battery.
