MacBook Pro battery conditioning
in [Mac Systems]

From: Paul Fuchs on 28 Jan 2010 15:35 A friend of mine in Europe bought a refurb MacBook Pro (15" , 2.53 GHz, 10.6.2) and says that this was the last of the removable battery models and it's down to about an hour. Is there a way to try to refubish the battery through software? Inexpensive replacements of reasonable quality. I got totally ripped off last year by a supposedly new Chinese replacement for my now dead Pismo. Useless. -- During times of universal deceit, telling the truth becomes a revolutionary act.

Essentially it involves using the laptop to where it shuts itself off because of the battery being drained. Then you recharge to full capacity. Unfortunately this does not always work. Buy a new 3rd party battery. I'm sure you can get one thru Amazon.

Before doing so, check the instructions on the Apple website, reconditioning is a different procedure for Li-Ion and Li-Polymer batteries. But basically, the older Li-Ion are reconditioned as you have already stated (iBook, PowerBooks etc.), but later models, like the MacBooks, use a Li-Polymer battery, which need to be left drained for an additional 5 hours before starting the recharge cycle. > Buy a new 3rd party battery. I'm sure you can get one thru Amazon. I got a Chinese cheapo off eBay for my daughter's iBook, which has been fine. YMMV applies of course :-) -- Andy Hewitt <http://web.me.com/andrewhewitt1/>

Also, make sure to check the number of cycles on the battery, in System Profiler under "Power". Batteries don't last forever, and if you're over 300 or so cycles you may be getting the best it can give. -- Tom "Tom" Harrington Independent Mac OS X developer since 2002 http://www.atomicbird.com/
