I'm at 652 cycles at 91% health on my Mid-09 15" MBP. I can see myself going with this battery for another 3-4 years easily if it keeps degrading at this slow rate. 1200-1300 cycles at 75% health is good enough for me for a 6-7 year old MBP.
I wish they had given the option of retina display on the unibody MBP as well! Hopefully that will be an option in the future!
Yes I have also same question.Why would they give you a new motherboard if your battery is damaged? What kind of nonsense is that. Changing the motherboard wouldn't even solve the battery issue. Apple will just swap out the battery and put a new one in. It's only glue people. My gosh...
Does anyone know if it's good or bad to leave the computer plugged in for a long time/overnight even if the battery is fully charged? Also is it better to discharge the battery in full before charging again. I called Apple twice on this and one specialist told me to leave it plugged in as much as I could and the other said it's better to leave it unplugged.
Imagine trying to use one from 2005 now?

$200 seems reasonable.

I'm sure if it were left to the aftermarket some various products (which may or may not be trustworthy) would probably start cropping up at half that price. Some which would almost certainly be a problem would crop up at a third of that price. I'm sure there's a little bit of a markup in there for Apple (though it will be off-set in small part by the labor of installation).It seems you and I have differing opinions on reasonable prices. £159 for a damn battery is daylight robbery.
My mid-09 MBP is at 79% health with 570 cycles.
$200 / £160 seems on the pricey side to me, but the rMBP is bleeding edge and Apple will make you pay through the nose for the privilege of having it. Lets face it, the price of entry for the rMBP makes most people's eyes water anyway so it's not really a surprise that anything connected with it follows suit.
I suspect newer iterations will have a more elegant servicing solution than a glued in battery, but I'd be amazed if Apple lower their price for replacement.
Ya' pays ya' money, ya' takes ya' choice.
True enough. The thing that bothers me most is having to ship the computer in for what should, regardless of price, be a simple battery replacement, but it is what it is.
I imagine that will be because of the glue.
*Glue* for a part that is probably the most likely to need replacement during the life of the machine. It's not an elegant solution, and it's very un-apple.
Lol. It's not just glue that you think of.
Industrial adhesives, like this, are used in more places than you can imagine. People really need to get over this and understand what the product really is. Un-Apple like? Seriously? It's not some sticky stuff that you might remember using in school.
Not surprising after seeing the insides! They'll have to do some crazy stuff to un-glue it!
At least their battery life estimates (for me at least) are better than what they claim, my mid-2010 MBP has been through 818 cycles and is at 90% health.

1221 Cycles on MBP Mid 2009 60% Health
You all seem lucky to me.
My early '09 MBP's battery fried after 250 cycles.
If i unplugged it, it would work for 5-30 minutes, get super hot and surprise shutdown with a disconcerting pop.
New battery immediately fixed it. Happened right after un-purchased Applecare would have expired anyway.
I'd fully drain/charge while off at least once a month too.
Hmm, perhaps I should Applecare the retina...
woah, thats strange. my mid 2009 mbp is at 89% after 300ish cycles and still lasts about 4,5h. thats 90 mins longer than my old vaio did on day 1![]()
I think you are overlooking the point, which is simply that you should not have to ship a computer off just to have the battery replaced.
There's no "should" or "should not" here. This particular product requires this particular service event, and it's part of the trade-off for the design choices that provided other benefits that probably convinced you to buy this particular machine.
You see this with automobiles-- some require specific servicing, and often premium cars require premium service. Why not computers?
I say BS.
Do you know how much time it takes to get everything out of the Top case/Unibody to actually replace it with a new battery, it will take hours.
You even have to get the display of.
My guess is that the battery is glued with hot glue, they will simply heat it up to lets say 60-70 degrees celsius and will remove the battery and glue in a new one.
If they have to replace the whole top case they would have to do way to much work, if they just replace it with all things inside the serial number would also be different since it is embedded in the motherboard.
They could discharge the battery first(to a hard 0%), Lithium Ion still holds a certain charge even when the computer says it's 0%, it gets cut of below a certain threshold/voltage (3.3 Volt) because if Lithium Ion goes below that threshold it will be broken.
Also the top case/unibody is made of aluminium and too expensive to just replace.
