An electrical apparatus, comprising:
- a secondary battery;
- a load which consumes power supplied from the secondary battery to implement a function required for the electrical apparatus;
- and
- a switch element disposed between the secondary battery and the load;
- the switch element remaining in an off state until use of the electrical apparatus is started by a user.
An electrical apparatus, comprising:
- a secondary battery;
- a load which operates by power supplied from the secondary battery;
- and
- a time measurement circuit configured to carry out measurement of a date and time at present by power supplied from the secondary battery;
- the electrical apparatus operating in one of a plurality of operation modes including a normal operation mode in which the load operates, a power down mode in which the operation of the load stops and measurement of a date and time at present by the time measurement circuit is carried out, and a shipment mode in which operation of both of the load and the time measurement circuit stops.
