I was wondering if there were any software packages out there that will prevent my laptop battery from charging above a specified level. I know there are propriety options out there for Samsung and Lenovo (I believe), but I'm looking for something that would work on any Windows 8 laptop. I leave my laptop plugged in all the time and I'd like it to only charge to 80% to optimize battery life.

Does the Samsung Easy Battery Manager run on non-Samsung hardware (I have HP)? If so do you know where I could download it (couldn't find it with a Google search). –  Kyle Aug 7 '13 at 12:44

HP sells Windows 8 laptops why are you unable to use the provided software? –  Ramhound Aug 7 '13 at 13:54
    
I wasn't aware there was an HP product that does this. –  Kyle Aug 7 '13 at 13:59

It came with your laptop. Every OEM has one and I know HP has one. The support article applies to Windows 8 h10025.www1.hp.com/ewfrf/wc/… –  Ramhound Aug 7 '13 at 14:12

If you leave your laptop plugged in all the time, then charge the battery to 80% manually, and then remove the battery and store it in a cool place (I.e., not by the laptop's exhaust fan). This will be far better than keeping the battery inside a hot laptop.

If you find that you don't really leave it plugged in all the time, then keep in mind that the internal circuitry on the battery will actually keep it at a good charge level for the charging/discharging that occurs.

from wikipedia: «It is recommended to store batteries at 40% charge level.» So, if you want to conserve battery capacity, discharge it to about 50% (60% is okay also) and store in cool place. And each year re-charge it and discharge to about 50% again. That's because battery will self-discharge 10-20% over year. –  LogicDaemon Jan 6 '14 at 18:39
    
another evidence: wired.com/gadgetlab/2013/09/laptop-battery (charge to 80%, discharge to 40%, store in that state) –  LogicDaemon Jan 6 '14 at 18:49
