Alright so i have my macbook pro for 4 months now , and my battery health is 97% ??

Coconut Battery:

97%
6755/6900 mAh
19 Load cycles
4 Months old

iStat Pro:

98%
19 Cycles

Am i doing something wrong?? i just calibrated my battery -->

1- Fully drain battery w/usage
2- Fully charge battery - no usage
3- Keep charging when full for 2 hours
4- Use

Laptop was in box for 2 months, only been using for 2 other months
Am i doing something wrong?
 
Are you sure that's a Pro? 2010 Pro? That mAh seems rather low. My 17" is reporting (Watts) 13000 original capacity, 12674 current capacity, for 97% capacity after 60 charge cycles.
 
Those were the numbers i got from coconut battery
Also when i charged the laptop fully and used for 2 hours, battery full is 99% ?

I'd download Watts and just verify that mAh. That just seems mighty low for a Pro. Worst case you might have Apple verify the battery's in good health.

Those aren't the steps for calibration.

This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ
 
Like the poster said above, that's not how you calibrate the battery.

Also, know that the percentages are estimates and can actually go up and down. 97% or 98% is fine. Stop worrying.

+1. Battery monitors are only an estimate. There is never a way to determine a batteries health that is 100% accurate. Anyone who tells you otherwise doesn't know what they are talking about.
 
"After your computer goes to sleep, turn it off"

How can i turn it off when it's in sleep mode ?

By pressing the power button. It's not necessary. Just let it sleep for 5 hours or more. It will shut down on its own.

After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.

Also, remember step 2, before you unplug and allow it to drain:
Allow the battery to rest in the fully charged state for two hours or longer.

I did

just one question:

When im draining the battery, the computer goes to sleep right.
Can i switch the laptop back on and continue draining the 5% left until it's 0 ? or do i have to wait 5 hours until it shuts down by itself

Once it drains to the point where it sleeps, it's likely that it won't turn back on, but you can try. Either way, you still have to wait 5 hours.

Thats my battery. Don't worry, battery health will vary between 90-100%. If it gets under 90% you should get worried, until then, its no problemo hose!

Get a little app called 'Caffeine'

It forces your computer to never sleep. Save your work, back up your data, and let it run on just the battery. With 'Caffeine' enabled, even when the battery charge reaches 1% it will not sleep. When the battery dies, the power will just cut off and your computer will shut off (from loss of power). Leave it like that overnight. Then charge it to 100% in the morning and leave it charged for about 2 hours after it reaches 100%. This last step means you leave it on the charger even if it says it has stopped charging.

Then use the computer how you like.

Finally 97% is pretty good. That's health my battery was in when I bought it.

Disclaimer: I am not liable if you lose any data or damage to your computer after following the steps I provided. Follow at your own risk. Always back up your data.

I agree! Great little app! Also, it's fine if you use your Mac while it's draining (save your work when the remaining charge gets low), and while it's recharging.

That's actually the 2nd step. This needs to be done before the battery is drained, not after.
The last step is:
Connect the power adapter and leave it connected until the battery is fully charged.
