Intellitec's Battery Guard 2000 saves your fleet vehicles from becoming stranded and in need of roadside service calls. The Battery Guard 2000 system prevents "dead" or "flat" vehicle batteries by disconnecting them before they completely run down and cannot start the engine. Battery Guard 2000 consists of three major components. Intellitec's patented battery disconnect relay, the waterproof RCU, and a dash mounted, reset switch. The battery disconnect relay and ECU are mounted near the battery, to disconnect it from the vehicle's electrical system. The reset switch is mounted in a convenient location on the dash. The entire system comes equipped with an interconnecting harness to simplify the installation. We normally keep the 24v 100 Amp version in stock. Please phone if you require 12 volts or 12 or 24v 200 Amp versions.
