    Well...

    If you have a laptop (or similar) with a sealed battery, it is imperative to let the battery fully discharge once in awhile.

    This is very important with Li-Ion batteries which use a special charging circuit and software routines to "trickle" charge the internal battery.
    OEM computers usually come with a battery maintenance monitor to tell you the health of the battery at any given point in time.

    Best way to conserve on the user level is to pick a conservative power plan in Windows.
    SSD based system will also give you more battery life than those with an HDD.

    FWIW.
    You never want to totally discharge a LiON battery. It actually causes the salts to stop holding a charge and can cause them to overheat.

    That is untrue from what I have been taught in the industry.

    A quick example is when your iPhone (Li-Ion) turns off due to insufficient charge. Nothing ever happened to those who recharged them to capacity.

    I would appreciate it if you could substantiate that claim. Thanks.

    May be a semantics thing. Totally, as in 0%, vs. letting the device shut off at a prescribed low threshold of, say 5%...like my Galaxy S4. Not sure I can get it to 0%, it stops and shuts off at 5%.

    Exactly. It is a real-world measurement. It's never zero until it's zero.

    I liked the first article but it really has nothing to do with the purpose of this thread, IMHO.

    BTW, we have similar backgrounds, lol.

    Hi!
    it is not good idea to keep the AC plugged in when the battery is fully charged. I used to do that and I damaged my battery.
    You can charge the battery and take it off and Work with pc with AC plugged at home in and use the battery later
    I use the AC instead of the battery all the time.
