*) In general, the batteries last 2 years. If you leave the modules switched on continuously, they will send out a signal more often and the battery will also run down faster. Also, a temperature below 0 degrees Celsius (32 Fahrenheit) has a negative effect on the battery life. Therefore, always take spare batteries with you. These are available in our webshop.
