Abstract
A battery tester and charger is provided for safely and efficiently testing and charging partially charged and discharged batteries. Information about the battery to be tested is inputed by the user. A first heavy loaded is applied and the bounce back voltage is used to determine the state of charge of the battery. If the battery is chargeable then a set charge time is determined. If not, then the battery can be discarded.
