Does your car eat batteries? First of all, if you ever jump start your car, you’ve hurt the battery. The best thing you can do is immediately commute with it for a day or two. Four to six hours of driving at any speed and jostling the acid will help it recover. If no one in your family commutes, then put it on a trickle charger overnight twice. I know, the alternator does the same thing, but it doesn’t. You need to get the battery absolutely topped off and keep it there a while to reverse the chemical process. Draining your battery until the car won’t start is always serious—start batteries HATE going below 50%. My wife’s 2001 Honda Odyssey eats batteries because the interior lights do not automatically turn off if the key is out for too long. Stupid design from an otherwise smart company. It has a seven hundred CCA battery that was down to 400 CCA, so leaving the headlights on for 5 minutes would make it not start. This was not the first battery that died early. So I replaced the car battery and installed this device. The install was easy, I put it on the positive side but I strongly recommend you put it on the negative side. You will have an exposed terminal unless you wrap it up, and it will probably not look good. Exposed negatives are better. Basically this is a smart relay. It monitors the battery voltage and cuts off all power if the voltage drops to 12.25 Volts. That’s probably realistically a 50% drop. You hit the button, start the car, and you’ve avoided 95% of the damage of a fully dead battery. If you have a short so that the car discharges on its own, that’s much worse. Use this device to shut off all power every time you drive, so the battery is 100% all the time. I stuck the wired remote switch underneath the back edge of the hood near the driver’s wiper. So my wife can use the remote, hit the button, or pop the hood and hit the button on the device. My daughter immediately clicked the wired button over and over. The car was dead. Turn it back on with a single click of the wired button, no big deal, but it took a while to figure out. The main wire is a gauge too light for my liking. I would not install this on a diesel. The voltage gauge that shows hundredths of a volt on the main unit is a nice touch. It only illuminates occasionally, but knowing the exact voltage of your battery is a huge plus. Back to my first comment, with this device, you can monitor the health of your battery and alternator. With a new battery turn off your car and let it sit overnight. The next morning, turn on the battery and look at the reading. That reading is good. Higher is better. It should be about 12.85V, but every battery is a little different. A slightly discharged or failing battery will show a lower voltage in the morning. Batteries always want to be fully charged, so if you see a drop of 0.10V, consider a long drive or an overnight trickle charge top up. Test your alternator by turning on the engine and every electrical component including the A/C and seat heaters. At idle you should see 14.1 to 14.4 volts, if so, you’re good to go. Unlike a dash voltage gauge, this thing is real. Do all this and you might get 10 years from a battery. ... show more

    • Needed a Battery Disconnect for my Motorhome
My first unit had a bad key fob. Amazon replaced it promptly with another one. Battery disconnect installs rather easily. One of the biggest issues I had were the instructions for setting how low to set the low point voltage before the disconnect actually disconnected the engine battery. Instructions are pretty vague and could use more and precise details for the low voltage setting. I have not checked to see if it will really automatically disconnect my engine battery or not. The engines ECM and probably the TCM have a constant draw on this battery, not to mention there are probably other parasitic draws too. My dad was the original buyer of this motorhome and then I took it as part of my inheritance. This motorhome has to battery disconnects, one for the engine battery and on for the house batteries which have never worked properly. And the dealer was unable to correct this problem, we've always had to manually disconnect the batteries. Time will tell how well this battery disconnect works. Right now, I give it Five stars. If I find it doesn't do its job, I will revise this review at a later date. Review Update: Today's date is 4/10/2024. I've used this unit for about 1.5 years so far and love it. I used to have to take the negative battery off (which was a pain) to eliminate all voltage draws from the engine battery. This works great. The only thing I've recently noticed is sometimes all 3 lights flash in succession, green, yellow, and red. I'm not sure why and I can't find information regarding this, but it still works fine. I would definitely buy it again. ... show more

I had hoped this would work. I installed it and found the remote switch didn't work. So I disconnected the switch plug and used fine needle nose pliers on the controller connector and that did work. So it looks like the aux switch is defective. So I turned to the remote, which I didn't want to do because it's just one more thing to have to carry. That kind of works but only some times. It is extremely unreliable. Well, there's another remote. Let's try that. Again, unreliable. So if my wife is stuck she can use the mechanical key to open the door, then open the hood, then pull off the battery cover, and then press the button on the controller. This works some times, but not reliably. I can't ask my wife to carry tools to reconnect the battery physically if the system won't reconnect ... I'm out of ideas. So I scan the QR code for help. All in Chinese with no option for English. So I go to the Amazon page from my order. No contact information. So I Google Tikscience. No luck for a point of contact. So I'm writing this in the review section in the hopes they can advise me on what to do. Anything that works can fail. It is impossible to obtain 100% quality control. I understand this. A But absent a response I'll be dealing with Amazon on how I can return this item. I'd really prefer to find a resolution ... ... show more
