AcuRite Weather Station Battery Pack (palo alto)

This is a battery pack accessory that is sold as an add-on to AcuRite 5-in-1 weather stations.
It allows the batteries to be accessed and changed from approximately 20 feet away.
The use case is if your weather station is mounted on the roof and is difficult to access, you can manage the batteries from a more easily accessible location down on the wall.
