The external batteries can be removed without opening the Mac, however they generally max out at 3 to 4 hours of usage before needing a recharge. Both battery types have their own strengths and weaknesses. There are Macs with batteries that can be removed externally, such as with the 2007 MacBook, and then there are Macs with batteries that are removed internally, for example, the 2011 15-inch MacBook Pro.
