Abstract: A battery circuit board includes a substrate, a first trace configured to receive a voltage and forming a first closed loop around a perimeter of the substrate, and a second trace forming a second closed loop around the perimeter of the substrate. The battery circuit board also includes an electrical assembly configured to determine a presence of an electrolyte on the battery circuit board in response to a short circuit between the first closed loop of the first trace and the second closed loop of the second trace.
