Review: Solved my mystery battery drain instantly—this little remote switch saved me a ton of frustration! - I installed the DZSSCY Remote Battery Disconnect Switch on my vehicle after dealing with an overnight battery drain caused by a grounding issue. I wanted an easy way to disconnect power without popping the hood every time. What I Loved: Instant Fix: With one push of the remote button, I could cut power completely and stop the drain—no more dead battery in the morning! Simple Installation: It attached right to the negative terminal, and the streamlined design made setup quick. No extra wiring hassle. Strong Performance: The 250A rated current and 450A peak handled my truck’s power draw easily. Versatile Use: Works great for cars, trucks, and RVs—any 12V system really. Peace of Mind: Not only does it prevent battery drain, but it’s also a solid anti-theft measure. Diagnosis, Not Cure: The switch fixed my issue short-term, but I later discovered my new alternator was actually faulty and causing the drain. The disconnect worked perfectly until that was sorted out. Final Verdict: This remote battery disconnect switch is a lifesaver for anyone fighting mysterious battery drain or looking for a simple anti-theft option. Easy to install, works flawlessly, and gives you total control at the push of a button. Highly recommend!
Review: So if you are an engineer like me this 2 wire cut off will work on the positive post - So here are pictures of the manual with some details and diagrams of what I am talking about. Would be nice if that was in the product description. So if you are an engineer like me this 2 wire cut-off will work on the positive post instead of the negative post for use as a shut-off. In my truck, my negative post is almost impossible to connect to and also I run dual batteries using an auto-isolation circuit so this needed to be set on the positive side of my battery to prevent discharge through the positive cable as the ground is shared between both batteries and the auto-switch is on the positive side and would require a major rewire job. So before you connect anything under the hood this is what you need to do with 86 and 85 the POWER POINTS for the electronics. The connectors for the batter on the outermost of the relay are NOT polarity sensitive so do not care if it is positive or negative or what direction the power is flowing. YOU MUST CHANGE THIS BEFORE YOU CONNECT ANYTHiNG TO USE THIS ON THE POSITIVE POST What the manufacturer did is they tapped the negative 85 using a short wire to the negative post for the circuit side then using a longer wire run 86 to the positive battery post. Then the relay when switched on connects the out port to the negative battery cable for the body ground. As this is ACTUALLY a 2-wire cut-off relay and THOSE 2 wires on 85 and 86 are what MATTER as to how they connect to power, the manufacturer just uses a short cable to the BATTERY SIDE of the cut-off part of the relay and that is what makes it polarity sensitive for negative side use. BUT what you can actually do is connect the relay to the positive post and the output to feed to the rest of the vehicle. the CENTER posts are the ones that you CAN NOT misconnect. To use this on the positive side instead do the following. REVERSE the black and red wires on the center 2(two) connections (85- 86+) so that the negative side 85- is connected to the long red wire that connects to the negative battery post and the positive side 86+ becomes the black short wire that connects to the positive post of the battery. A relay is a Relay or a basic switch that is opened and closed by a magnetic coil being energized and in itself the contacts are not polarity sensitive. It is the electronic circuit on the CENTER post which IS POLARIZED!!! Doing the above or even eliminating the manufacturer cables and electing to use longer red and black cables to provide power to the 85 and 86 on the relay to the correct terminals will allow this to work on the positive side of the battery. Not all installations can use the negative side of the battery in my case I need to be able to cut off the positive side due to the DUAL battery system and shared negative connection. If this is reposted I will add photos of my configuration when the sun comes out as the Delivery was late at night and there was not a lot of light and I have been dealing with the power drain problem for some time and disconnecting and reconnecting my battery using a jump box. In my truck someone tried to jimmy the door locks so instead of replacing them I added power locks and an RFID pad to unlock the doors, there is no other way as there is not a working key lock, it has to be the RFID pad or using the power locks relay via the wireless door lock remote. Have to get access to the hood release which is INSIDE a LOCKED vehicle to then attach the jump pack. I have jump posts on the outside but too much cable causes too much resistance and it will not start with a dead battery and the jump pack with all that cable resistance even using 2 gauge cable is to much resistance for efficient starting. But the door locks will operate.

## Features

- Iterative upgrade: Remote battery disconnect switch is an upgraded version of the previous generation product. Compared to the older version, this product uses a mechanical magnetic switch that has A standby current of only 0.003A, completely solving the problem of parking power consumption.
- Smart Voltage Safet Kill Switch: If the voltage is lower than 11.8V, the remote kill switch will automatically cut off the power supply after 120s to save electricity. if the voltage is higher than 13.2V, that is to say, the remote control will be disabled while driving to prevent power outages caused by accidentally touching the remote control switch while driving.
- Manual Control Option: Remote battery disconnect switch 12v includes a manual control option that allows the user to manually disconnect the battery switch if necessary. This remote battery kill switch is useful in emergency situations or when working on a car's electrical system.
- Protect and extend battery life: Due to its long-term parking function, electronic device power consumption, wiring aging, and forgetting to turn off the lights, this remote battery protects and extends the battery life by cutting off the switch.
- Reliable Quality: Your satisfaction is our motivation and quality after-sales service is provided to meet any of your needs. If you have any questions about your purchase and use of the process, feel free to contact us, The professional customer service team will provide you with satisfactory solutions within 24 hours.

### ⭐⭐⭐⭐⭐ Great for classic cars, adds security, easy install, best upgrade to date
*by K***S on December 3, 2025*

Best custom addition I've made to my C3 Corvette. Since I only drive my classic cars intermittently, my car batteries will drain between drives. I installed knife switches which work great, but they are cumbersome to access every time I want to drive. This remote switch brilliantly solves the issue. The wiring install was simple, but the physical install was a bit tricky (was working in a tight space on a battery that didn't have posts), but I got it to work and wow is it fantastic. Adds a layer of security as well since would be criminals have to bypass the remote switch to activate the battery. Something to be aware of, since the remote has the ability to deactivate the battery at any time, it is possible to cut off the battery while driving, which obviously would be undesirable. I love the convenience of being able to activate/deactivate my battery with the push of my remote. Will be buying more of these. Great value at this price, highly recommend!
