We have several vehicles which are rarely used, and used to use trickle chargers. They're not always convenient to keep plugged in, and after several months, don't seem to always keep the batteries fully charged. This simple switch works well, and have had no trouble starting vehicles after long dormant period. It's very simple to install.

Good value and does the job. Will only work on negative terminal side. Positive side has a bigger post.

Great product for plows and other vehicles that sit for a while or have a slow drain somewhere and it's not worth the repair.... but be warned this does NOT fit all battery terminals, as a matter of fact it's fairly small and cannot be adjusted. This product is not lead, its steel and cannot be opened up, half of the clamp will snap off in your hand. The clamp is also relatively thin so you wont be drilling it out either..... MEASURE YOUR TERMINAL

Seems like a solidly built switch. It was easy to install and is easy to know if it is on or off.

This product is amazing!. Battery cutoff switch that installs in less than 1 minute for this price! Love it. The folks breaking the plastic, are just torqueing the bolts too much and twisting the plastic base. The base of course, has to be non conductive material, which leaves two real choices, Plastic or Ceramic. Ceramic is brittle, and Plastic is not as strong but not as brittle. I am glad for the plastic base. Just use your head and hold the contacts as you tighten the clamps. The leverage is the key. Do not lever the base, and you will use this switch for many years to come. Hook it to the negative side only. Works great. Might not be copper, but who cares. Spray with WD40 every few weeks and corrosion will not be an issue. you should be doing that to the battery terminals anyway.

Use this on our Jeep we tow behind the Motorhome. So easy for the battery disconnect.

It works like it’s supposed to. Saves a battery on a sitting car.

I used this product to keep the in-tandum batteries on my motor home from needing a trickle charger when stored.
