電に入るような充電器がある。BACKGROUND OF THE INVENTION Conventionally, there are constant current and constant voltage charger methods. In this method, after charging starts, the charging voltage changes to the set voltage C.
;Charge with constant current until it becomes , then charge with constant voltage. In addition, to prevent overcharging (2), there are chargers that use a timer to set the constant voltage charging time to a fixed time and enter trickle charging after constant voltage charging.

発明が解決しようとする問題点 上記のタイマを用いて定電圧充電時間を一定時間とした
充電器（：おいては、放電量の少ない電池あるいは満充

なくなる等使用効果は極めて大なるものである０Effects of the Invention As mentioned above, in the present invention, since the constant current/constant voltage charger (:) controls the constant voltage charging time by the constant current charging time, optimal charging is possible regardless of the discharged TiLf. Since overcharging can be prevented, the effects of use are extremely large, such as reducing the capacity drop due to liquid reduction (2), especially when increasing the control voltage for sealed storage batteries that cannot be refilled with water.
