What does the Mini Add-A-Battery do?
Adding a second battery prevents getting stranded with a dead battery by isolating the start battery from the house loads that can quickly discharge a battery.
The Mini Add-A-Battery offers a compact, simple way to control the switching with the m-Series Dual Circuit PlusT Battery Switch and automatically share a single source of charging between two batteries with the Mini ACR Automatic Charging Relay.
