Abstract
A testing device and method may be implemented for improved detection of leaks in batteries used in portable electronic devices. The leak testing device may use two high voltage electrodes to detect ionized air leaks. The first high voltage electrode may be configured as a test voltage, and the second high voltage electrode may be configured as a reference voltage. The first high voltage electrode and the second high voltage electrode may be configured as current limitation resistors. The leak testing device may include a processor that measures the first high voltage electrode and the second high voltage electrode. The leak testing device may include a display that is configured to display a difference between readings of the first high voltage electrode and the second high voltage electrode.
