Sterling Battery Maintainer

Quick Overview

Yet another fantastic product for those of you that are having problems with flat engine batteries. Save money on batteries and stop them being destroyed by discharging.

This three wire simple to install, low cost product is ideal for vehicles with solar panels, battery chargers or any other power source that only charges the leisure batteries.

Availability: In stock



How it works

This unit is activated when the main battery has reached about 13.3 volts and allows excess power to be transferred from the primary charging system to charge/maintain an auxiliary battery bank. Don't be fooled by cheaper imitation products, this unit will transfer up to a 3 amp charge from one battery bank to the other.
