Periodically inspecting lithium batteries can help detect early signs of damage or flaws that may lead to leaks down the line. Giving batteries a quick visual and tactile inspection monthly is a good habit. Look for any noticeable swelling or deformation in the casing, as this indicates dangerous gas buildup and imminent failure.
In contrast, common battery types such as nickel-metal hydride batteries and nickel-cadmium batteries use liquid electrolytes to transfer charge, so if these batteries are damaged or aged, they may leak. The electrolyte of lithium batteries is solid, so even if there is a problem with the battery, the electrolyte inside will not flow out.
Common lithium‐ion battery types. Testing for leak tightness requires some form of leak detection. Although various leak detection methods are available, helium mass spectrometer leak detection (HMSLD) is the preferred and is being used broadly to ensure low air and water permeation rates in cells.
This breakthrough leak-detection technology for all types of lithium-ion battery cells represents the single most important leak-detection development in the past 10 years, not just for the automotive industry but for the makers of smart phones, computers, consumer-electronics products and a variety of medical devices as well.

Battery cells or housings are filled with helium and placed into a vacuum chamber. A leak-detection system can then measure the amount of helium leaking from the component being tested. Over a given period of time, a leak rate can be determined. For this type of test, a leak rate of 10-6 mbar∙l/s is normally used.
