I don't drive my Blazer nowadays as much as I like. I wanted to make sure I don't drain the battery while it sits and have a surprise one day when I actually need to drive it.

Has anyone installed a battery cutoff switch and if so, what kind?
 
yup I bought one that clamps on the battery terminal then the battery cable clamps on to it. It was like $5 just spin a knob between on and off :D

how bout you elaborate on that.... what brand.. how many amps....

I was gonna do the same thread.. but wondering what all yall winchers are using... as i am going to need something good to 500 amps... :haha:
 
New one..

They have a newer version of the "knob" style switch,that has a small wire and a fuse,so your radio and computer wont lose their memory while its in the "off" position..only thing that sucks,is if you forget to tighten the knob first before starting,you pop the fuse! :doah: ..

I'm not sure how many amps those terminals are rated for,but I bet they wont take 500 amps for any length of time..Being cheap,I just take one battery cable off myself,if I'm worried about something draining my battery.. :crazy:
 
I have one mounted on the floorboard of the 83 K20 that I picked up last month from a local fire department. It is a nice bit of insurance against the battery running down when the truck is parked for a while, and also serves as a quasi-theft deterrent.

On the downside, I have no idea how it was installed. :dunno:
 
If you like elaborate (read that as "expensive") Flaming River makes an awesome one that is tough, and has a long extension handle you can mount in the cab and disconnect/reconnect the battery at will. I think it's like $125, but I've always wanted to get one.
 
Check in some boating catalogs, they have some nice switches. Summit and Jegs also have cut-off switches.
 
I just found a Hella cut-off marine switch on eBay for $8. It's the Hella model 87181, rated for 1000amps/12v. Maybe I'll give that a try. If I have to open the hood to use it so be it. It has a key that removes also.

I am using a marine battery switch that doubles a my dual battery manual isolator. Got it locally and it only cost about $40

It is good for 300 continous amps and I think 700 short amps and around 1000 peak amps.

(Glows in the dark too)

That's the one on my Sub too.

I have one of the Hella's with the removable key for the Dune Buggy. Doesn't look like it will get installed. Perhaps on it's Baja replacement. Have a second for the Project: Rusty. That key will BE the IGN key - goal for it is simplified wiring.
 
I installed a battery maintainer in my K5.

Picked it up from NAPA for about $30. Cost more than the switches, but it keeps the battery fully charged and ready to go. I have yet to suffer a dead or frozen battery since I started using it.

Of course that means you have to plug it in.

Couldn't find the NAPA number, but here is a similar unit from J.C. Whitney for $20
