Abstract (en)

[origin: CN109073712A] A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery; and a display electrically coupled to the processor. The display is configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.
