It may be an old battery, and you may be not charging it all the way, or a combination of both. I wouldn't worry about it at all.

The g2 battery may need a slightly higher voltage to charge completely. As it is charging the internal resistance of the battery increases and a higher voltage is needed, which the charger cannot supply. Therefore it charges until an equilibrium is reached which in this particular case is 70% or thereabouts. It has nothing to do with 3,000 mah or 3.200 mah.
