You can generally expect to be able to use them for about two years. The number of transmission signals does not affect the lifetime as much as long cold periods do.
The radio components use standard button cells (type CR2032). These button cells can be stored for up to ten years (refer to label). However, the button cells should be replaced every two years in order to adhere to the warranty conditions (the manufacturer offers a 2-year warranty against leakage).
We recommend to use Panasonic batteries.
In order to remind yourself to replace the batteries in time, we recommend to change them, for example, with every vehicle inspection and/or gas inspection.
If the battery is running low (<2.6V), the control unit issues an acoustic signal (for two seconds) when triggering the radio component and the red LED of the transmitter only turns off after about 30 seconds. If one button cell is weak, it is best to replace all of them.
