Macbook Pro low battery warning to instant recharge


My Macbook Pro (Mid 2012, OSX 10.10.2) sometimes gives the Low Battery warning, then immediately after dismissing the notification the battery pops back up to about 25% battery, still showing a red battery icon.


It is above 20% but is still red.

What could have caused this, is it an error in Yosemite OS X, or is it a reserve battery power I did not know about, or is it something completely different
