    On my cellphone I wait til the battery is totally discharged. Should I being doing the same with my laptop, or does it not make a difference?

    When ever I have access to external power I will use it. This way the battery will get charged for the next time I do NOT have external power.

    Okay, DaveA! Cool! I was wondering about that. I also read not to leaving it charging for more than 24 hours at a time.
    Thanks for the info. (y)

    Most of time, my laptop is on 7/24 on external power.
    Mine has a charging program that controls when it needs to be charged or not.
    Just make sure that it has good air flow on the bottom side.

    From the link, and a problem I see most prominently:

    The "Memory Effect"
    "Memory Effect" is a condition of reduced battery performance (and eventual failure) due to a battery only using those cells that are fully discharged and charged on a regular basis. In other words, if on a regular basis a NiCd or NiMH battery is only partially discharged before being recharged, it " forgets" that it has usable capacity to further discharge all the way down. The result is degraded battery performance and shorter battery life because the battery is using less than it's true full capacity. Li-ion batteries do not develop the "memory effect". NiMH batteries, while considerably better than their NiCd counterparts, are prone to developing "memory effect." However, proper care and conditioning over the life of a NiMH battery will significantly reduce the potential negative impacts. Back to Top

    Thanks, loserOlimbs! My son made me aware of that problem with my cell phone that I wasn't allowing to discharge fully.
    Gotta let them go all the way down, or they forget that they can go all the way down. :eek:

    I suppose I have something similar. It tells me that I'm getting dangerous close to the end. I thought I'd try to get her as low as possible--got to shortly after 9% left when she clicked off into hibernation.

    I'll check out the bottom side too. Thanks! :)

    No problem, I see this all the time with a 1 year old laptop. The user has no idea why their almost new laptop only gets 30 minutes on a full charge... its because they never drain it down and have essentially killed the battery.

    Ahh, so! It's endemic! as I would imagine. Takes awhile for the word to get out. And there's no fix for the problem? Were they purposely engineered this way? :(

    The information is really only apliceable to rechargeable batteries in household appliances.
    A Laptop battery, never totally discharges, as the laptop switches itself off long before it gets to that state.I understand that nothing is achieved by supposedly applying that practise.
    Like Davea, my laptop (it is an enormous and heavy 21 inch) , is used more as a staionary. It is on main power, through the battery, of course, 24/7. Currently it is four years old.

    There is no fix, its a result of the technology used. There are types of batteries like those commonly in laptops that suffer from the memory effect and get less life if you don't run them down before recharging. There are also types that if you drain them down, they lose life.

    And non-rechargeable batteries can explode if you try to recharge them. Just the materials that used has its own characteristics.
