Description

The ADD-A-BATTERY is as simple to operate as an ON-OFF switch, yet effectively manages the switching and charging of two batteries from a single charge source

The Add-A-Battery includes a Dual Circuit Plus? Battery Switch and an Automatic Charging Relay. These components simplify switching and automate charging, so that all you have to do is turn the battery switch ON when you arrive and OFF when you leave.

Simplifies switching
Isolates engine and house circuits
Combines batteries for emergency starting
Tin-plated copper studs for maximum conductivity and corrosion resistance

ACR Automatic Charging Relay

Automatically combines batteries during charging
Isolates batteries during engine cranking and when not charging
Shares the charge between two batteries more efficiently than a battery isolator
Allows efficient dual battery charging without needing regulator adjustment or rewiring
