what do I have to do to keep my battery alive?

>>55059060
set charging thresholds and cycle them as little as possible

lithium likes to stay between 30-70% charged (~3.80 to 3.85V/cell)

If you are using the laptop stationary, drain the battery to 75% and remove it

Old laptops are the best. Everything made after like 2009 is planned obsolescence garbage literally designed to break.

Five years old Samsung X430, battery lasts about an hour of light usage (internet browsing). I hardly ever leave my house with it anymore though. I have a phone for that.
