description Said invention discloses a charged for restricting lithium ion battery charging method and protective circuit protective circuit, in charging to lithium ion battery, through comparing detective lithium battery discharge voltage with configured rechargeable lower limit voltage to determine whether charging lithium ion battery or not. Said invention provided protective circuit includes double voltage detect IC unit and charging IC unit, wherein said charging unit accessing power supply, to proceed charging to lithium ion battery, said double voltage detect IC unit output controlling charging IC unit piece level signal to control charging through detecting lithium ion battery voltage state. Said invention can fully utilize lithium ion battery charging times to raise lithium ion battery service efficiency and prolonging service life.
