I see 300 cycles on most of those packs. But if you had say a 1000 amphour battery and a 2000 amphour battery yes you can guess which one will give you more hours of use before it degrades and dies. But the pressure is on makers to fit just a big enough battery so you rarely see more than the usual size and time.
If your laptop battery has more cells (such as 9 or 12), on average, would it last longer than a battery with fewer cells, if all other factors are essentially equal?
In other words, do more battery cells make the battery last several months or even years longer?
