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 being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

Methods of coating contacts to have a specific color. The color can be selected to match a color of a portion of a device enclosure for an electronic device housing the contacts. Examples can instead provide methods of coating contacts to have a color to contrast with a color of a portion of the device enclosure. These methods can provide electrical contacts having a low contact resistance and good corrosion and scratch resistance.
