    Is there any way how to "charge" battery to its designed capacity?

    My battery is 2 years old and I was wondering if there is any way how to "renew" it (except buy new one)?

    Hi, can you tell me what program you are using in your screenshot?

    I also have a battery which is somewhere around 1/3 of it's original capacity and it's only 1 year old :(

    I think there's no other way of "renewing" it except for purchasing a new one. How much wear does your battery have already? By the way, I think he's using CPUID/HWmonitor in that screenshot.

    No this is normal pattern for laptop batteries. Unfortunately you can only expect 1-2years of daily use from a battery before you will start noticing reduced battery life. 2-3years and the battery will hold less than half of its normal charge. I would get yourself a new one if I were you.

    To keep your battery in good form, you should fully discharge / recharge the battery regularly and try to avoid times where you only partially discharge the battery before charging again. Although these batteries don't suffer from memory effect like ni-cads, they do need exercising properly to get the best life out of them.

    You have to send Chekov to collect some high energy photons from an naval reactor. Once you have these photons inject them into your battery and you should be good to go. :D

    Thanks for help.
    The program is CPUID HWmonitor.
    Chekov is on holidays (pity).

    guys, please help me out on this question:
    once my battery is fully charged and I plug in my AC, will the laptop use the power from my battery or the AC power at this point?? if it only uses the AC power when the AC is plugged in, then it is ok to leave the battery in the laptop even if I don't use it right??? I am worried the laptop will keep using the battery power while the AC keeps on charging the battery....in this case, I guess I will have to take the battery out when I am not using it.....

    Windows will keep charging battery once battery level drop below threshold probably near 95%. Battery will drop 3% per day even you are not using.

    Apparently freezing the battery and then touching an arc welder to the cells can get some of the life back, you would have to be really carefull about the welder bit though.

    The theory behind it is that after a while the lithium starts to go hairy inside and eventually starts to short out the battery as it has grown from both terminals to meet in the middle. The logic is that freezing it helps to break up and loosen the fuzz and that nuking it with a welder further destroys the fuzz, thus helping the problem. I wouldn't expect it to be back to what it was when it was new but the guy who's video it was said that he went from getting less than a minute or so of life to over ten (really old laptop that was under constant use).
