I`ve just bought my new macbook Pro 13, but I have some doubts, like:

 

You can`t take the battery off in new MBP! And people say that it`s not good use the battery with the energy! How do I deal with that? People say that Mac`s batteries don`t get adicted! Is it true?

 

The other doubt is that I installed Parallels and people say that this software cause many damage to the battery. I`ve read a topic about that and I took some steps to avoid it!

 

My battery sometimes causes that it`ll take 7 hours to get down but other say that will take 4 hours, it has been oscilating. Is it normal? How can I fix it?

 

Thanks in advance,

John.

    Newer kind of batteries do not have memory problem.

     

    The battery in this MBP 15" uses about 16% per hour.

     

    So your experience appears normal.

    What people?  Parallels may draw more power since it is processor intensive, but it's not going to damage the batter.  The only thing that will seriously damage the battery is putting it on an unprotected outlet and getting hit by lightning.  Or pouring a cup of coffee on it.

     

    Don't worry about not removing it.  It will last over 1000 cycles, and that's just to get it down to 80% of maximum charge.  You have years of life on it.  YEARS.

    Yes, it's OK. That figure will fluctuate up and down by as much as several percentage points from day to day and week to week throughout the battery's useful lifespan.

     

    Don't obsess over your battery. It's fine.

    The only probelm was that a release of Parallels caused one of its background processes to work overtime and make the Dock use nearly all the processor cycles. This was only after you upgraded to OS 10.6.8, not Lion.
