    How Long Will a Fully Charged Battery Hold Its Charge?
    I have a spare battery for my White, 2.4 ghz MacBook. It's from another macbook in which the logic board burned out, so i can use the parts. If i charge this battery fully and keep it in my laptop bag, how long does it hold that charge? Thanks for any responses.

    No, I'm saying, if you don't use it... just charge it fully and then store it for a time when you're not near a power source or something... when you install your backup that you had fully charged... how long until the power is dissipated just from sitting there? thank you.

    If it's not for a prolonged period of time it should hold it's charge for awhile. Based on this link:


    Apple - Support - MacBook - Care and Handling

    When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from the MacBook. If you are storing your computer for an extended period, recharge your battery to 50 percent every six months or so.

    So I say if you are going to be carrying it with you only to use in an emergency, you should be good for about 5-6 months. I'd recharge it maybe once a month if you haven't used it.
