How Long Do Galvanic Cells Last

Generally speaking, sensor life is expressed in terms of months in room air. The average sensor generally contains enough fuel to last for up to 4 years. Because most devices are used in higher oxygen partial pressure environments than room air, life expectancy can be significantly reduced from the quoted specification. It is recommended that sensors be stored in a cool, dry place when not in use. Sensors can be purchased fresh when needed here, and replacement sensors should not be stored on the shelf for any length of time. Storage in a refrigerator is also not recommended because of the high humidity environment.
