They are very advanced (and much different) than others out there, although they may share the same cell types. Each battery contains it's own circuit board and intelligent charging system. The base merely contains the power supply/converter. The charging portion is in the battery itself.
The machine knows every battery that has ever been mounted to the machine and that specific battery's past performance characteristics. It knows when a battery has been attached to it for the first time as well. It knows when cells start to over-temp or are beginning to go bad. A truely "smart" battery.
Nobody, that I'm aware of, has anything like it. Why do you think they are 1/3 of the price of the machine?
