Your Battery Life at 400 Cycles?

Yes I agree, I replaced mine with 80% capacity because it was only lasting a few hours. Free replacement from Geek Squad Black Tie service plan. The new battery is just perfect, been on it off and on all evening and still at 46%.
I'm 804 cycles in and I'm sitting at 71%. Would I qualify even though my Macbook is now 40 months old? Seems too good to be true!
Otherwise, does anyone know the costs of a replacement battery? Cheers!
Defective batteries are only replaced free if still covered by warranty or AppleCare. Apple charges $129 to replace the built-in batteries. Read the Battery FAQ for more details.
you can get that replaced, that's awful.
Isn't it something like if it goes under 80% that quick you get a warranty replacement?
Hi guys, I really need to put my mind on ease so need your help.
I have an early 2011 Macbook Pro 13" with 318 cycles and the battery is already dead, marking it to be replaced.
Is this normal???
According to the knowledge base it should be able to cycle close to 1000. I'm not expecting it to hit 1000 but 318 and already dead??

And as mentioned here,
I'm going to call Apple and ask them but just in case anyone here can tell me if this is normal situation?

No this doesnt seem right my Core 2 Duo didnt hit that until 775 Cycles and my 2011 13" didnt hit that at 550 when I sold it.
My mid 2010 15" is running on its 960th cycle with 87% health. However, I hardly get more than 3 hours of light usage with less than 10 tabs of Chrome and VLC (non HD). I do, however, have an SSD and a HDD installed. When I start using it like a Pro, i.e. Lightroom, a Virtual Machine and some other stuff, battery life drops to an hour or less.
I suppose that at the end of the day, battery health is just a number. It's the actual usage that counts.

112 cycles on a 2011 MBA with 92% health left.
Can you tell I haven't used it much? Had it since new!

What is the battery health? Has it dropped below 80%? Apple has no control over your cycle count.
What does "dead" mean? Service battery message? Doesn't charge? Apple does indeed guarantee that your battery should never dip below 80% capacity if under 1000 cycles. They replaced mine and the machine was out of warranty.
mid 2010 13" MBP, over 3 years old now.
Getting about 6 hours wifi surfing with 1/2 brightness. I suppose it can do 8+ hours when text processing at min brightness and no wifi.
Its mostly used from 100% to almost 0%, so naturally its getting a workout.

I'm guessing this isn't great, my computer is plugged in to my TBD so I suppose that could be a factor, but only have Safari and Mail open...
256 cycles @ 88%

The TBD certainly is a factor, depending on which MBP you have.
If it has a discrete GPU, plugging in a TBD activates it, so power usage goes way up.
