Answer 3

I’m sitting on a thikpad t420 9-cell battery while it was new, it held 10-15 hours with an average load and Windows optimization, you can insert batteries instead of a DVD and also cut it from below in the form of a docking station, it seems like it will work for 30-40 hours,
but the battery capacity drops about every year 2 times, as a result, after 2-3 years with a daily load, it holds 6 hours, 10 hours with an average and minimum load
