**Q: Approximately how long do the batteries last on the receivers?**
A: Dear customer,
Thanks for your question.
For PR13 FM Receivers, it uses 2 x AAA batteries, but it not included in the package. The lasting time of the battery usually depends on the capacity and the quality of the battery. 
And the different volume will also affects the lasting time. You can divide the capacity of battery by 50MA to calculate the lasting time of the battery.
