    Call me old fashioned but charging my 2009 Macbook pro when I first got it seemed to do wonders for it battery life. Are there any battery experts amoung us who could fill myself and everyone else in on any 'first charge rules' that should be followed? Once my lil i7 arrives tomorrow I wanna condition that battery to it's peck optimum, as I have a trans atlantic flight on Sunday and need my N64 fix for preferably the entire flight :)

    Thanks guys.

    I am curious about this too. I have read that it is best to set a battery to charge only up to 98%. Not sure what to set the minimum value at that would designate at what % the battery would start to charge. Can anyone verify any of this?

    It's a Lithium-Ion battery, it will arrive charged. Top it off if needed and you good to go.

    After the centuries of testing in IBM labs, millions of dollars spent, countless posts on NBR forums... there it is... the discovery that easily overshadows Einsten's theory of relativity, Darwin's theory of evolution and probably work of Isaac Newton and the discovery of the calculus itself...

    Ladies and gentlemen... I present.... [drums pls?]

    THE battery charging protocol (v1.0, probably found in Notebooks for Dummies):

    1. Plug in one end of the AC adapter in the wall.
    2. Plug in the other end of the AC adapter in the designated spot on the laptop.
    3. Contemplate the meaning of the life itself while the energy from the AC current gets converted into chemical energy on your brand new battery.
    4. ???
    5. Profit!

    Thanks for the response guys. Guess I'll just plug her in when she starts screaming "10%......****ing 7%!!! Get off of GTA and give me some energy!!!'

    Come to think of it, that sounds awfully familiar....... :-s

    Damn, I've been using v0.9b of the battery charging protocol so I've been plugging in the other end of the AC adapter in my USB ports.

    I always though it was from a full batt you use up all the power out of it till it shuts down then give it a full charge again and then your good to go.

    Yes. The battery will ware and continue to loss capacity over time. Now people have said its not good to dis-charge the battery only 10-15% (so there is 90-85% remaining) and then charge it back up. Other than that I don't really baby the battery.

    Lithium-Ion cells should never be fully discharged as it could damage the cells. They are not subject to memory effect so it doesn't matter if you charge them at 15% of 60%.

    Rhodan,
    what would you set your battery charge options to in windows? i.e. start charging at X%, stop charging at Y%

    I think you got this one wrong, step3 should be.
    3. Ascend into higher plane of existance(if you watch Stargate SG1 you should know what this mean), where you get rid of your human body form and live as energy form. This you could continue feeding energy to you M11xR2 forever.

    Working IN the business I can tell you right now that in order to get the best life out of a Li-Ion battery... you take it out and put it on a shelf. Otherwise, just charge it whenever it's convenient, ie. just got home, plug it in. W/E. Unless you discharge a Li-Ion battery completely, it doesn't really matter. Your notebook will shut down with about 2-5% total capacity left in the battery every time. This is a fail safe to protect you and your investment as a discharged Li-Ion battery can be dangerous.

    So TL;DR: Charge it when you want.

    No need for that, lithum-ion batteries have a built-in logic boards that monitor charge levels, temperature and charge cycle. It's all automated.

    The best way to way to get most out of your lithium ion batteries is to use them. Keeping them on a shelf does nothing to help as this type cell starts degrading as soon as they are manufactured. My last M1530 was plugged in 95% of the time for 2 years. When I sold it the battery still had 88% of its original capacity. Leaving on the shelf would have resulted in the same capacity loss...

    They have built-in logic to stop carging when they are full capacity anyway so you gain nothing by taking them out.

    Most newer notebook, have the ability to shut off power from going to battery if it doesn't hit certain point. In Fujitsu if you battery is 90% or over, and you plug into the outlet, it won't charge it. This is how manufacturer prolong battery life. Also, if you don't intend to use the battery for a long period of time, don't leave it empty or fully charge. Leave it about 40-60% before storing it. This is why most cell phone and stuff don't come w/ fully charge battery.

    that explains why ipods, mobiles etc always have enough power in them to say that you need to charge. i've always wanted to use that little bit extra power to get a few more minutes of entertainment but now i don't =S

    Good luck trying to hit bottom on a battery. There's so many safeguards in place in most electronics that it won't allow the battery to go to zero.
