I'm the host of a tech podcast called inThirty. Guess how long each episode is?
Check it out.

Antwoord op "Can new battery be used in older MacBook Pro 13""Thank you for responding DJT, but I have to disagree with your method and answer. If your initial response was based upon incorrect deduction and not experience, I'd like to point out that different does not strictly mean a part is incompatible, especially considering that Apple uses batteries with different watt-hour ratings within identical models as a matter of course. Check a few System Profilers on the same model Macs and you'll get different manufacturers and firmwares and mAH ratings. I can't find an article that says the batteries are a different physical size. Also, see this thread and the teardown I reference within, please: Does the new battery last longer, or is it the laptop itself? As per your reference to wishing you could upgrade the battery in your 17" MBP, I guess you have the Mid 2009 revision. I cite Apple's own specifications for your model and the early 2010 model to show that they both have 95 watt-hour batteries: 1) MacBook Pro (17-inch, Mid 2010) - Technical Specifications:...
Antwoord op "Does the new battery last longer, or is it the laptop itself?"That's a good question. Ifixit does indicate that the 2010 13" MacBook uses a battery with the same dimensions and part number as the 2009 model but with only a 350 mAH greater charge (and it's 7.5 grams heavier): MacBook Unibody Model A1342 Mid 2010 Teardown The increased battery life, therefore, is due to the 2010 model's CPU, GPU, chipset combination. All things being equal, increasing the battery capacity by 350 mAH alone would net only about 30 minutes longer life in the old model if you were already getting the rated 7 hours. Just for reference, another hardware change (perhaps the only other substantial one), is that the 2010 version's Mini DisplayPort provides audio out while the 2009 model does not.
Antwoord op "Can new battery be used in older MacBook Pro 13""Hey DJ Tarazona, can you post the source for your answer? Do you think a full Logic Board switch is possible (if unreasonable) to also get audio from the Mini DisplayPort?
