What is your battery's health stats?

I am quite paranoid as I bought the 15" 2.4GHz macbook pro on Saturday and according to Coconut the capacity is at 96% and maximum battery charge of 5414 mAh (5600 original). It has had 3 cycles. I phoned Applecare and because it is only a few days old they told me to go to my nearest Apple Store and get a replacement laptop but I don't think that is necessary and it is around 30 miles away. They also gave me the option to send out another battery but I am trying to improve these stats by calibrating and so on before I ask for that new battery. What does everyone think about these stats, the laptop is 2 days old?

What is your battery stats for your Penryn Macbook Pro?
 
If they are offering you replacement battery just take it... I don't get why you would decline that--they send battery overnight, you put the old one in the box and ship it back!

When did you get yours and what is your battery stat if you don't mind me asking?
 
Lion batteries start degrading the moment they step off the factory line. A newly purchased battery @ 96% of original capacity is doing pretty good, and is about what is expected. I'm surprised they offered to send another one. Lion has great energy density but has other properties that are less desirable, limited lifespan being one of them.

My first one was February 26th (first day of Peryn), 105 cycles with a 95% health, around 5900 mAh

My replacement on June 1st (first one warped, so they swapped me a new machine), 8 cycles, 100% health, at 6471 mAh

Mind you I have the 17" model

Is it possible to get mine to 100% capacity? Any tips or suggestions would be greatly appreciated.

Because of the within 14 day return policy they offered me a new machine or laptop-whichever I prefer but the machine is literally perfect so I'm keeping it. I just need assurance it is normal and not a defect.

Take the replacement; calibrating is really not help most of the time; you just use a cycle; I didn't say it doesn't help, just since your computer is so new and they offered a free replacement, take it.
 
It's normal, just do a full discharge/charge cycle once a month and you should get at least 300 cycles of 85%+ capacity out of it. I use my laptop mobile a lot, 350+ cycles a year so I burn through batteries in under 2 years.
 
When I got my MBP on 14 May, it was in the 6300s. It eventually dipped into the 5900s, before I did a full discharge/recharge. It's right now at 6229, 14 cycles, and at 99% (according to iStat Pro). I mainly run mine off the power supply, with the occasional sojourn into battery usage when I'm out and about.

Like everyone else has written, you might as well get a replacement battery. This way, you can properly condition your battery for maximum usage.
Someone can correct me on this, but you might be able to run your computer off the power supply while you're waiting for the replacement battery.
[edit] Turns out you don't have to wait for the replacement battery, before you send in your old one. Even better.

Hope this helps,
Esther

Well since they send you the replacement battery first, there is no need for that.
 
I got my computer about a month ago. It started with 100% health and wavers at 94% now.

99% i guess apple didn't think I would ever use this thing without both charging it and using it mobile on a day to day basis.
 
When you first get a macbook or macbook pro what are you supposed to do about the batter? Do you charge it up then turn the machine on and start running from the battery on its first run or what? It is also saying the battery is fully charged at 99% now, surely there is something wrong?
 
Health: 97%
cycles: 38
Capacity: 5442/5600
age of mac: 2 months (this is wrong, don't know why, my mac is about 5 weeks old)
 
Phoned Applecare and the very cheeky person told me there was no recollection of me calling yesterday so "legally I didn't call" he said. I gave him the same info from System Profiler, I told him the health from Coconut Battery and he said 3rd party applications can damage the system so told me to delete it. He asked me to take the battery out and so on and hold power button in for 10 seconds. The magsafe is green reporting fully charged but it goes to 99%. He asked me to calibrate the battery to which I told him I have already done a few times but because of how cheeky he was and telling me I didn't phone he said if I didn't want to do it he would put it down as a refusal to co-operate with troubleshooting steps on the case which could result in me paying a 10% restocking fee if I took it back to the point of sale. I told him I live 30 miles from the Apple Store so that isn't an option. I have to calibrate the battery and phone again tomorrow, if it doesn't work it will go down as DOA which will mean I have to send this back first before I get a replacement sent he said. He said that is standard policy but it is at the discretion of the Customer Relation Team to alter it in individual circumstances e.g. send new one out first which is what I need because only computer I have. The person I called last night was nice but tonight was completely the opposite, extremely cheeky and stubborn.
 
Went to Apple store today and spoke to a very well mannered and kind specialist (retail assistant). The guy was extremely helpful and all I did was tell him what happened and without mentioning what I wanted or anything he had a brand new machine ready for me. I think my experience today shows the level of customer service the employees at the Apple Store give but I think their call centres which deal with Customer Service and Applecare have challenges ahead for delivering the best service to customers instead of treating them as an enemy. What I experienced today is what a company is all about, great products and great aftersales service incase of issues which unfortunately I experienced.

Well Done Apple Store Employees:D:)
 


That's fantastic. Nice to hear. I think my battery is OK, but my magsafe keeps being odd and sometimes doesn't charge upon first connection. :confused:
