Thread: Battery Master Disconnect Switch

Tweet

The easy part is WELCOME! Best car forum on the net, right here!!

While I don't have a disconnect in mine, I've seen a few that can handle some high amp ranges. Do some reading at Summit Racing dot com and - or Jegs, review the spec lists and see if they've got one that'll fit your needs. Some batteries out there have 500 cold cranking amps (or more!) so you'll need to be aware of what your battery can produce. Also, try not to crank over an engine for more than 10 - 20 seconds at a time, they develop a lot of heat with all those amps!

Write back and let us know how you make out.

I'll add my welcome as well.

Many, if not most of the battery disconnect switches sold in the US are made by Cole-Hersee, even the Longacre Racing versions. Their amp range goes way up !!

Here's their web site - choose one then do a search: Battery-Related Products | Master Disconnect Switches | Cole Hersee - Littelfuse

If I recall, mine is 175/1000, but CRS often takes over but 175/450 should work
