Can the BatterySAVER PLUS be left outdoors?
Yes, but it should be treated with silicon as the BatterySAVER PLUS was designed to sit on the dashboard inside your vehicle, and has not been weatherproofed. To weatherproof the BatterySAVER PLUS, apply a clear silicon sealant around the glass and plastic edges as well as on the connector on the back of the panel (where the wire goes into the panel). Outdoor use without weatherproofing will void the warranty.
