Abstract
For charging a secondary battery, at least two operation modes including first and second operation modes, in which the secondary battery is charged to predetermined charge end voltages different from each other, are established. Both life and capacity of the battery can be maximized by a user selecting either of the two operation modes, or switching between the two operation modes automatically with a timer device, or according to a temperature of the battery, state of health thereof, or internal pressure thereof.
