new macbook battery

hey guys i just got my macbook whte unibody monday this week and i calibrated my battery, used coconut battery and it says i only have 99% of my original battery cap left. is it normal for me to lose 1% already in 3 days? it says my macbook is 2 months old though, would it have decreased while it was stocked? before i calibrated it showed me with over the cap (5545/5450) now its 5430/5450. maybe im just being paranoid

thanks

 

There is nothing wrong with 99% Health. You're just being paranoid.

 

Li-ON Batteries will degrade even if you aren't using it. An average lithium based battery shelf life is about 2-3 years. So, I would say it's about right...

 

My battery died after 11 month from moderate use, so you never know

 

Mine just died after 14 months.

 

I know you guys are saying it's normal but i checked again just now and it's dropped to 96%, i checked with coconutbat and istat pro.. is this a sign of bad things to come

also i checked on system profiler the first time i booted the mac up and it was always condition: normal did i get an older battery? i thought it was supposed to say great or good when it came to a new macbook

 

I guess I'm doing pretty good.

 

The more you keep your battery on charge, the better health it gets. i've seen my health decreasing to 94% due to using it on battery constantly and a few days on charge and the health sky rocketed to 99%.

 

That's not entirely true. If you don't ever use your laptop battery and always use it on AC, your battery will most likely suffer a premature death.....essentially from lack of use.

It's a good idea to cycle your battery at least a couple times a week.

And again, to the OP, you're being over paranoid and fixating on numbers. Use it, and enjoy it! That's what it's there for.

 

Capacity varies depending on the conditions e.g. temperature and stuff like that, if you drop below 90% within a few months then contact apple

 

lol 7 load cycles in 15 months?

 

I'm willing to bet if you started using the battery a few times and then calibrated it, you'd see a large drop in your capacity.

 

Probably, but it rarely leaves my desk so I don't care

 

Except that one time when you have to leave your desk, with your MacBook, without the power adapter, to show the CEO a financial presentation that the future of the company relies on.......only to have your battery die and the company fall into bankruptcy! LOL

 

My battery health initially dropped a few points after the first few load cycles, then climbed up to 100%, and has held a capacity higher than it's initial value since then. I think I am at about 40 cycles and 9 months.

 

samy happened to me xD but im at 100+% after 166 cycles and its been calibrated xD and my mbp 17" is on arround 2,000 cycles and 78%
