Abstract
Systems and methods for implementing a safety circuit in charging devices are disclosed. In an exemplary embodiment, a method may include closing a latch to stop delivery of a charging current to a battery when voltage produced by the battery indicates that the battery is non-rechargeable. The method may also include dropping a threshold from an initial value for the voltage produced by the battery to a baseline value so that the latch remains closed even if the voltage produced by the non-rechargeable battery drops below the initial value of the threshold. The method may also include resetting the latch each time a battery is connected to the charging device.
