It is possible to provide a mobile electronic device which can accurately judge the service life of a cell even when the cell is replaced. Provided is also a method for controlling the mobile electronic device. A control block () includes: a voltage measurement unit () which is connected to a charge cell () and measures a voltage value of the charge cell (); and a control unit () which performs control to measure a voltage of the charge cell () by the voltage measuring unit () upon each start and end of charge of the charge cell (), stores in a storage unit (), information on a number of charge/discharge times identified by the measured voltage value, and outputs information on the service life of the charge cell () according to the information on the number of charge/discharge times from an output unit (equivalent to a display () a speaker ()).

A fastener including a pair of base members formed in the shape of a band and a claw unit formed between the pair of the base members, and the claw unit engages the base members with each other and seals a gap between the base members. The claw unit includes a sealing unit and an engaging unit. The sealing unit includes a male claw and a female claw that receives the male claw so as to make an area between the claws liquid-tight or air-tight. The engaging unit includes a pair of hooks. A side wall of the female claw of the sealing unit is formed as a restricting part that prevents a displacement of one hook of the engaging unit in a separation direction.

It is possible to prevent charge of an incompatible secondary cell while suppressing the size of a mobile electronic device and a secondary cell without increasing power consumption so as to prevent damage of the secondary cell or the mobile electronic device by charge. A detachable secondary cell () supplies power to a mobile electronic device (). The mobile electronic device () includes: a cell terminal () which outputs and inputs power to/from the mounted secondary cell (); non-contact information extraction means () which performs a magnetic field communication; a loop antenna () which transmits/receives a signal using an electromagnetic wave by the non-contact information extraction means (); and control means () which acquires particular information outputted from the non-contact information extraction means () and controls charge of the secondary cell () according to the acquired particular information. The loop antenna () is arranged in the cell terminal ().
