I assume the question is about whether there is an external battery that can be changed in a jiffy. No, there is no external battery. The housing has to be completely disassembled in order to access the built-in battery and replace it with new cells in the future. That would be more the domain of Makita, Bosch or Black&Decker in this price segment. Trisa has something similar with exchangeable batteries, but you can't get to the batteries practically anywhere, and if all price sensitivity has gone, Dyson also has this.
