I bought a new macbook pro yesterday 11/04/13. I had it on charge all day but the percentage bar only reached 97%. I shut down and kept it on charge over night and this morning it was still only at 97% when I sitched it back on. Why is this? I feel it chould reach 100% at some point... Thanks!
MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.2)
See the Apple article below.
The macbook battery system is designed not to charge the battery fully in short cycles. This is to prolong the battery life. I found with my macbook pro that if i take it off the charger and run it on battery power until the battery is completely drained then it will usually go right up to 100%.

Why doesn't my new macbook pro battery charge to 100%? It only ever reaches 97%
