    Hi,

    my MacBook Pro's capacity is only 40% of full potential.

    When should I buy a new battery?

    (Or should I just buy a new computer :)

    Buy a new one when your current one can no longer hold a charge for the amount of time you require out of it

    Buy a new one rather than replacing the batter? ... Yet the computer is just fine!

    I believe he meant buy a new battery when it can't hold a charge long enough to support your needs. You don't need a new mac if your current one is working fine.

    I would buy a battery off of eBay. The batteries are usually much cheaper that way.

    The 2006 models are still good computers. If it seems a little sluggish as well. Then try to upgrade the RAM and hard drive, from Newegg.com or other cheap online retailer. They are cheap upgrades and give an amazing performance boost.

    I've been seeing a lot of batteries on eBay going for about a 3rd of the price then the batteries in the Apple Store. I know eBay is the King of Knock Off though, would it be safe to put one of those batteries in your computer?? Last thing I want is for my computer to blow up.

    Thirteen months ago I bought a FastMac battery for my MacBook. It's gone through 196 cycles in that time and it's full capacity is now 2011mAh. I don't remember the exact mAh but it was over two years of use and a hell of a lot more cycles before my original Apple battery got this low. In hindsight I'd have bought an Apple one.

    I have a linked problem so I decided to put my question on this thread, hopefully ok for everyone.

    I have owned MB Pro for about three years and it has in practice been always connected to power cable, only very rarely I have used it with battery. Now my computer has started to switch off immediately, if the power cable is cut off accidentally. I have also tried to start the computer without plugging in the power cable, and nothing happens. Is it really possible that the battery can finish that completely, even if not used hardly at all? Is there an application where I could see the current battery capacity?

    For something a bit more refined, you can try coconutBattery.

    Sorry but I cannot find this "Power" option from there. According to coconutBattery, the battery capacity is 100%. This gets even more weird. Is there anything in the settings I could have ruined?

    I suspect you will need to replace the battery. Take the computer to an Apple store and ask if they have a spare you can test with.
