    An equal number do not. So the point is...?

    I think that the point is;

    Should one keep the laptop plugged in all the time, and only rarely use on battery only? Or just plug in to charge and run on battery only?

    Which is better for the battery, ie keeping it topped up all the time or cycling it all the time? What type of batteries do we have anyway?

    Fermier,

    Play the game! I'm sure you were able to decipher the OPs intended meaning here.

     

    I don't actually know what is best, I wish I did!!

     

    If you continually run while plugged in it will eventually kill the battery.

    If you continually cycle the battery it will eventually kill it (spec sheets normally specify the expected max number of cycles).

     

    Depending on who you ask, you will likely get a different response.

     

    For what it's worth, I tend to run from mains and do a full cycle about once a fortnight.

    Hi guys,

    If we want to use the battery for a long time we should do this :

    - Never work with do battery only until reach less then 12%

    - Charge the battery until 100% after that remove it and use just the AC adapter ( when you can)

    - Use the battery from time to time and do not leave the battery without using it for a long time (it will be damaged)

     

    Important:

    When we use AC adapter with a full battery (100% ) continuously and day after day we simply reduce the life of our battery

    Hope helps you.

    Mr H

    Not to question the veracity of your statements, but on what basis do you make them?

    Are they based on folklore, your personal experiences, opinions of others or on documented independent studies? (Independent studies are other than those funded by battery makers.)

     

    I would really like to resolve this.  Are there any Electrical Engineers out there, or battery designers who understand the technical aspects of this and are willing to share?
