    Okay so I was wondering if it was possible to stop the battery from constantly charging when i have the battery in (its charged to full) and my laptop is plugged in? Because I know that constantly charging the battery will lower its life, and I had a bad experience (power went out =/) with not having the battery in while the notebook was plugged in.

    Like there is there Vista option for this, or a 3rd party program or anything to stop charging the battery once it becomes 100% full?

    I believe the battery automatically stops charging once it's at 100%.

    If the battery is less than 100%, it will charge. If you never use the battery, the little trickle charges wont lower it's life nearly as much as draining the battery (i.e. using the battery and not AC).
    I wouldn't worry about it really. Otherwise, I would suggest buying a UPS and unplugging the battery.

    The battery has enough circuitry to decide when it needs to charge or not. Just let it do its job and it will suit you well.

    well... usually; laptop charges its battery till 100% and it will stop charging it; then when it drop to around 80% it will start charging again. on some laptop such as lenovo thinkpad; it comes with thinkvantage software which enable it to change the charge level; if my memory serve me right.

    oh and and when the machine is connected to the adapter; it bypass the battery and provide power straight to your machine; thats why when you have no battery but plugged in to the power adapter; the computer still run.

    But the conventional wisdom in the threads about maximizing battry life suggest keeping the battery charged at only 40% instead of 100%. I have seen discussions of aps that purport to do that very thing. Stop the charge at 40% and only allow it to go 100% at the users direction.

    That's only if you are storing the battery for a long period of time. There is already circuitry to do a trickle charge.

    i have the same battery problem. Was mostly using my desktop before i decided to get myself a laptop, so didn't know much about protecting or extending your battery's life span especially, if you keep your AC power in while the battery is fully charge and then you have to go through the process of calibrating and all that. Right now my battery does not hold any charge and does not charge to 100%, was 82%, then 72% now 65%.

    It would be great if there was some sort of software or circuitry in the battery or PC that let it knows that it is fully charge to cut the power and use the battery's power or vice-versa just to expand the life span of your battery. Cause right now i need a new battery, i cannot go out with my pc on battery power, will only get like 20 min the most and this time i'm going for a 12 cell.

    Batteries have circuitry to stop charging when it reaches it's maximum charge. I have it on my laptop just in case there's a power failure. If you're battery doesn't hold charge that means you need a new one... they don't last forever.

    You have to property charge a new battery. The recommend way is to charge/discharge at least 3 times but don't discharge all the way.. 20% is fine. LiOn don't have memory effects. I still have a 2year old HP battery and it's still charging to full capacity.

    Thanks for the info about at what point to discharge to. I was always unsure about this.

    How about a quicktip: How to Prolong your Laptop Battery
    My inspiron 5150 which is dells most badly designed laptop for me is now dead but the battery is still good. why? because I experimented with it for almost a year to get the truth about batteries...well 40% Rocks... and at least once a month full discharge.

    Anyway, Read it or neglect it. No problem :)
