12 volt battery disconnect kill switch

If you plan on leaving your car parked for a while and don't want to come back to a dead battery this is a cool product for that.

Lol I'll paint that (Red) ground wire black so more people won't get triggered. Didn't feel like buying a new roll of black wire for a small section.

I think you should clean the corrosion off of your wire connection. Corrosion offers resistance which lowers the available current and voltage. 😎

It doesn't eliminate all the current going thru the battery. Just enough to keep the vehicle from starting. Will not stop a parasite drain.

Jeez, who put red covered wire on a negative terminal... tut, tut.

[JIMinBama]

Same one is at Harbor Freight for $5.00 :)

i bought this today as a way to mitigate a parasitic battery, under 10 bucks installed in ten minutes, works great.

I bought one yesterday at wallmart for $4.something, torally recomended! to the peoploe that did NOT read the Notes... te Red cable on the Video Its NOT the Positibe he used an extra cable.. thanks for the vid man

Nylon spacer means conduct area is very small and this can cause charging, or operating issues. If your having earth type problems on your car / boat, check this first!

Pretty good video, but why do you show a red cable to the negative?

[niaz.shovon]

Looks like u need to tighten a bit more...

[EvendimataE]

NOW THAT YOU HAVE THE BIG GREEN KNOB THERE, NO NEED TO WORRY ABOUT WHAT PEOPLE WILL SAY ABOUT THE RED WIRE....LOL

[hhhclte]

Can you test it with the knob completely taken out? It could act as a key of sorts too.

Why to ground side ? Is the device not Amp rated ? For someone unable to locate an existing short drawing down the battery and the vehicle somehow gets grounded the battery can continue to drain. Example a farmer with tractor pulling implements that are Iron connected to tractor and no tires. In this case the negative connection would not help, you would need to find one with a positive disconnect.

[autoworldgentech]

Does it gets completely cut off cause on DMM it showed a bit of current .

[fordmantruck]

one more note.never ever ever buy any car parts from walmart. use a good quality prats store like NAPA. your local guys

[mcplutt]

Wow, this made a bad connection. The battery cable terminal wasn't clamped tight to the battery switch post at all.

[stevemiller]

I have one of these, rest assured that the main body parts of this item are not brass, merely brass colored base metal.

I like the concept but it's still showing current is being drawn from the battery.

What's the use of it if you're wanting to use it to stop your battery from getting drained? A buddy of mine is having problems with his lawn mower battery not staying charged and this wouldn't fix it.

[garycarroll]

My cable ain’t long enough grate video

[silviugsg]

Does it hold up well after multiple disconnects? Do you still recommend this product?
Thanks!

[CrazyAboutCycling]

It’s not perfectly disconnected. There’s still some power loss. So not the best long term solution.
