batteryhardwaremacbook pro
The macbook i am using currently is MacBook Pro (13-inch, Mid 2012). Now the battery warning is "Replace now" state. So i need to change it. I have another macbook with MacBook Pro (13-inch, Early 2011).
Is it possible the replace battery from MacBook Pro (13-inch, Early 2011) to MacBook Pro (13-inch, Mid 2012) ?
The built-in battery of your MacBook, MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity. Link.
Little differences in capacity are normal and are no indicator for a defect battery. Only contact Apple when your battery performes worse than the design capacity.
All the information you get from fancy 3d party is already in your system (that is where they get it from anyway).
Open your About This Mac, more info, system report and find Power:
It will tell you all about your battery.
It looks like this on my system:
Normally the Battery will keep a small reserve charge to be able to report its status to the computer. In your case somehow it was sucked dry completely :)
The good news is it is the battery, since your SMC is working and everything else is working based on the message "Replace battery". That same message was probably run all the time during your vacation, till the battery was exhausted to the level were the battery build in chip did not have enough power to talk to your OS. As for what caused that drain? did you leave your computer in a sleep mode ?

According to iFixit they would appear to be the same part.
