US Patent 11187752 Battery leak test device and methods

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 include a chamber configured to hold a device under test. The chamber may include a conductive foam, a conductive liquid, or any suitable conductive material. The chamber may be configured to hold the device under test in a substantially airtight environment and prevent or reduce air ionization under high voltage. The device under test may be a battery that has a conductive outer layer.
