iButtons have a very long lifespan and are extremely durable. Though they may resemble a watch battery, they contain no power source to run down. They’re guaranteed for 10 years, but we’ve found they usually last far beyond that time. However, like any other product, there is a chance (miniscule in our experience) one could be flawed. Here’s how to test your iButtons:
- Tap the iButton to a timeclock station that’s receiving power. The station does not need to be connected to a computer, nor does the iButton have to be set up on the system.
- If the timeclock emits a sound or any text appears on the LCD screen, the iButton is working correctly.
