An electric toothbrush with a rechargeable battery includes a chassis having a rechargeable battery receiving section and a bobbin section, which are integrally formed to each other and are aligned along a common axis in said order. The rechargeable battery receiving section and the bobbin section are connected to each other by a pair of connecting arms extending generally parallel to each other. A rechargeable battery with tongue shaped terminals is accommodated in the rechargeable battery receiving section. In the chassis two openings are formed to have an easy access to the tongue shaped terminals. At a time of disposal of the electric toothbrush, a user can remove the rechargeable battery by cutting the arms to remove the bobbin section, and cutting the tongue shaped terminals to remove the body of the battery. In other embodiments, an inductive charger and method of forming the same is disclosed.
