A high quality and affordable product designed to isolate the battery from the electronics that create parasitic draw. Save your battery and ditch the charger!

Currently ONLY for LHD vehicles

Problem:

As summer winds down, putting your car into storage for the season becomes a routine task for many. However, this end-of-summer process often comes with the annoyance of a dead battery. When a car is parked for an extended period—whether it's weeks or months—the battery can drain due to parasitic draw. Modern vehicles are equipped with various electronic systems that continue to consume power even when the car is turned off. Components such as alarm systems, clock displays, etc, can gradually deplete the battery’s charge. 

Solution:

The HCE battery isolation switch is a high quality and practical solution to isolate the battery from the electronics that create parasitic draw. All materials and components used in the kit are the highest quality possible. 

Features:

- A bracket assembly with an industrial design that follows the firewall line for a more compact and integrated look. Easily reachable from the front and sides of the car.

- Mounts to the firewall without any drilling, cutting, or modification. The bracket assembly uses existing mounting points. Installation of the bracket assembly takes only a few minutes at most. 

- A disconnect switch rated for 1000 cranking amps. Switches are sourced from and ISO supplier and go through an HCE post process to increase strength and durability. 

- New ground cables are batch manufactured in-house from motorsport grade 1awg copper cable with hydraulically crimped terminals.
