Battery Master Disconnect Cut Off Switch 6V 12V 24V Negative Post Marine Boat Car Rv Vehicles Battery Saver (Top Post(6V / 12V)-360 Degree)-1

I have a parasitic drain on my truck battery that I haven't been able to track down. If it sits unused for 3-4 days I have a dead battery. Installed this before I went on a trip to see my grandchildren. Used it to cut off the battery before leaving and and the to cut the battery back in when I returned. Worked perfectly. Was easy to fit in place.

Work well on my dual battery setup. I can imagine times I'd need to rapidly disconnect batteries, and so I fitted this to both. I had charging issues, which I realized were due to not tightening this enough - tricky in the confined space I have. Make sure it's right, and it works very well.

I was hoping this would clear the small space, but alas, no. Item great and I have one for my s2000 that works very well. (Lots more space around the battery). My 2011 335i Convertible battery space was too small to accommodate. Very good return options.

I have used the swing bar design of battery cutoff switch for many years and really like them. Decided to try this screw knob type. I learned quickly that the screw mechanism can loosen on dirt roads. The manufacture quality is just ok. I will replace this one as soon as I return home from this trip.

The unit snapped while I was adjusting its position. I would not recommend it.

I saw these things in car magazines, and they really work. I have a truck I don't drive much, and I have to continually recharge the battery. After installing this beauty, no more. Months later it'll start right up. The fact that it can be used as a theft deterrent was an extra value I'd never thought of. If parking outside overnight in Atlanta, you can bet I'll unplug the battery with a twist of the wrist. Very easy to install. Make sure you order the right size. Thanks !!

Having issues with an old vehicle and was able to use this to stop the battery from draining. Now I don’t need to disconnect the cable with a tool each time. Just turn the knob to put on or off.

I bought it as an alternative to the traditional knob on top battery disconnect that I've used for years on my other classic cars. This was different so why not on my new project, well it is no more. My downpipe touched the ministarters positive contact creating a dead short. Luckily I had the disconnect, when it made contact the lug that the battery cable attaches to blew off stopping any further damage. Fixed the problem and unfortunately had to deep six the disconnect. It did it's job and then some.
