Problem battery iFixit store.
I bought a new battery on iFixit store and I just replaced it.
After replace I left my Mac on charging all night for more of 12 hours for first charge.
This morning the battery was successfull 100%, although after about 2 hours or less of not using (stop mode) it is on 73%. I don't know what could be the problem.
What can I do to solve?
Update
Now with new battery Coconut sow me this...
Is this a good question?
