Ampper Top Post Battery Disconnect Switch 12V - 48V, Marine Battery Switch Disconnect Power Cut Shut Off for Car, RV and Boat (Negative, On/Off)

The installation process was straightforward and took only a few minutes. The switch is designed to fit perfectly on side post batteries, and the included hardware made it a breeze to secure. The quality of the materials is immediately apparent—this is a solid, well-constructed product that you can tell is built to last. Performance: After installing the switch, I noticed an immediate improvement in battery life. By simply turning the switch to the "Off" position, I can completely disconnect the battery, preventing any drain when the vehicle is not in use. This feature is particularly useful for my RV, which sometimes sits idle for weeks at a time. Since using this switch, I've had no issues with a dead battery, even after extended periods of inactivity. Ease of Use: The on/off operation is smooth and effortless. The switch is clearly labeled, making it easy to operate even in low light conditions. I also appreciate the compact design, which doesn’t take up much space in the engine bay, yet it's still easily accessible when needed. Versatility: What really stands out about the Ampper Side Post Battery Disconnect Switch is its versatility. It’s compatible with a wide range of vehicles, from cars and trucks to RVs and boats, and supports a wide voltage range (12-48V). This makes it a great investment for anyone who owns multiple types of vehicles.

Bout this for my truck that seems to draw power when it sits, even on a new battery. It took a few other parts on how to get it to fit properly but it works as described. Functions properly and seems well made. There’s no rattling or anything. Looked pretty cool under the hood and was easy to set up. Not bad for the price

Works great. You may have to swell the positive post but well worth it.

The switch itself is good. however the post for the battery cable is too small. My factory battery cable when bottomed out was still loose. I fabricated a copper shim to wrap around the post and then installed my battery cable over the post and shim to tighten the cable. Easy fix for a mechanic but the average person without mechanical experience will be returning the product or will need to take it to a mechanic to make it work.

this is really a must have if you need to kill your battery connction overnight without the need for tools. the fitment isn't that great though. the battery post side of it is way too small. I had to get a pair of spreader pliars to widen it for the battery post to fit, and then had trouble screwing the clamp so it doesn't try to undo itself. put two shims on to make it work. I'd get it again, but I'd honestly want to mod it so it's not

How I love to write good reviews, but unfortunately on this product it was a major disappointment. First of all, the battery terminal they climbs onto the battery itself was way too small and I didn't want to bend the metal too hard because when just utilizing it a little bit to try to make the opening wider, the metal looked very cheap and then when I looked up the reviews many people said because of the poor quality metal that terminal would snap. Secondly, the auxiliary terminal that went on to the cable that is from the engine was way too small-and there was no way to tighten it to the main wire that usually goes onto the battery. All in all it was extremely disappointing and a lot of hard work for nothing because when I got it hooked up and checked all connections, while it could run the lights, and the battery was just charged-it just did not make a good internal connection-the whole thing was a waste of time and as I said, very disappointing. I can't believe all the good reviews on the item, it shakes my confidence in reviews in general when I see a product like this, and just picking it up in your hand and feeling the lightweight construction of the metal, is a certain telltale sign that it's just not quality. ~Sorry to the people who make this, it's always much more fun to write good reviews and if there is another side to this, and you feel my reviews unfair, I am always a person who is open to being corrected.

I found this item on Amazon last year and thought it would be just what I needed to make disconnecting my NEG battery cable easier when I knew my car was not going to be driven for a while. Once installed, which is very easy, this switch has worked great without any hassle. I am now a repeat buyer and can say that both purchases have been great. We have 2 cars which are not used often and have always disconnected the NEG battery cable from the battery so as to keep the battery charged when the cars are going to sit around for a few weeks or months at a time without being started. In the past, I had no problem removing the NEG battery cable from the battery by loosening the nut. But to do this you need use your tools, and when you do this over and over, sometimes it makes the nut a little sloppy, after a while, I was not really able to tighten everything down as I would like to do, from the repeated loosening and tightening of the bold/nut. Now that I have installed this switch, it makes the process so much easier! First, I don't need any tools, I just pop the hood and turn the switch to red (off) when I'm not going to use the car for a while. When I'm ready to drive again, I pop the hood, and turn the switch to green. (see pictures) One thing to note, once the battery is turned off, you will need to open your car door via the physical key, because the key fob (push button) will no longer work. Since we rarely used the actual key prior to this, we sprayed some graphite power in the key-hole just to keep everything lubricated in there so the key would turn easy. I hope this review helps, I know this item is made in China and some of them have been DOA, but both the ones I ordered have worked great out of the box and held up for months so far.

Nice product

بعد تجربة اسبوعين ممتاز

Se observa de buena calidad, veremos cuanto tiempo dura con el calor.

Ottimo prodotto per sezionare un impianto. Nel nostro caso lo abbiamo inserito sulla batteria motore così che quando il camper resta fermo nel periodo invernale possiamo disattivare la batteria.

عندي سيارتين وحده فيهم قليل استخدامها وتفضى بطاريتها كل فترة وشفت اصحاب القوارب والجت سكي يستخدمون هذه القطعة لانهم نادراً ما يخرجون القوارب للبحر. سعرها مناسب وتركيبها سهل للغاية اشبك طرفها جهة السويتش الاحمر مكان كيبل بطارية السالب (-) واشبك كيبل السالب في الجهة النحاسية للقطعة وبعدها حرك السويتش للعلامة الخضراء لتشغيل السيارة او للعلامة الحمراء لفصل البطارية
