About a month ago I bought an Apple battery charger and several sets of Apple labelled rechargable batteries. Today I replaced the batteries in my Magic Trackpad with batteries that had been recharged. When I then looked at the charge sstatus it was stated that the Magic Trackpad batteries were 60% charged. Is this an indication that the rechargable batteries hold a smaller charge than the "regular" batteries?
NiMH batteries are notorious for appearing undercharged. Don't worry about it.

I wouldn't trust the charge meter too much. The only way to know how much power is in NiMH is to count coulombs (amp-seconds) going in and out. Even the fanciest computerized NiMH chargers often must use the "it's getting hot now" method for ending a charge.
NiMH also temporarily stops working after storage. They'll go back to normal after a few cycles of use.

The answer is appreciated! I didn't know what NIMH stood for and did a quick Wikipedia lookup at <http://en.wikipedia.org/wiki/Nickelmetal_hydride_battery> which was quite helpful.
