Abstract
An electronic apparatus comprising a plurality of loads, which are separately driven by a plurality of batteries, further comprises a switching device which automatically changes a system of connection between the batteries and the loads in accordance with the conditions of the electronic apparatus. Such conditions of the electronic apparatus include the remaining capacities of the batteries, load changes in the loads, and temperature changes in the electronic apparatus. An electronic apparatus provided with a system clock generating device and a peak load device comprises a system clock controller which suspends the supply of a system clock or divides the system clock while a peak voltage is being generated. A drive controller changes the connection between the first and second batteries in accordance with detected remaining capacities of the first and second batteries.
