How Long Do Static Electricity Release Devices Last?
Static electricity release devices (including fixed and portable types) typically have a long lifespan, lasting several years or even longer under normal use, depending on their type and battery condition:
* Fixed Static Electricity Release Devices (Sphere-type): Passive design (no power supply required), using antistatic conductive materials or metal, with no moving parts, extremely long lifespan (usually 5-10 years or more), requiring only periodic cleaning of contacts and checking of grounding.
* Portable Static Electricity Release Devices (Antistatic Keychains): Usually have an internal LED light as a discharge indicator, powered by their own battery. They can be used indefinitely as long as the battery has power. Even when the battery is depleted, they usually still provide resistive discharge.
