While the portion of the vacuum which houses the battery comes apart from the pole/roller portion; no their is no way to charge JUST the battery. If you are thinking along the lines of purchasing a second battery to exchange out, when the one dies, this vacuum doesn’t work that way. I will tell you that I have yet to have the vacuum go dead on me during one vacuum session (lol). The battery has much more stamina than I do. This is my second Moo Soo and I am a big fan.
