Stupid situation: You stand near the car and cannot start it, because yesterday you left the headlights, radio tape recorder or lamps in the cabin on. Compounding this by the fact that I have not recharged the battery to the required values for a long time.
So I had a problem in late autumn, a new battery up to 7 volts sat down deeply. Many people know that a voltage drop of up to 5-7 volts at negative temperatures turns the battery into a piece of lead, due to the fact that the electrolyte is divided into two parts water and sulfuric acid. The first one freezes in the body and destroys the plates. Which makes the appliance unusable. Fortunately for me, the battery was reanimated.
I am glad to welcome you to the author's channel "Timofey Mikhailov". Today I am sharing with you information about a very necessary device for me. I bought it with my own money. Not advertising.
In order to prevent such situations from recurring in my life, I decided to fork out to buy a device that will disconnect the battery before a strong discharge occurs. A kind of electronic mass. I ordered it on the Internet because I have not seen them on sale in my stores.
When this waterproof (IP 69k) device came to me, I decided to immediately mount it on the car. During the editing, a neighbor "swam" up to me and began to ask what kind of "stray" I had in my hands and how much it cost. Having announced the price, he began to smile and said that for such a price tag you can buy a new battery. To which I objected to him and began to explain the principle of the stop discharge.
If during idle time, the voltage in the on-board network drops sharply, this can lead to battery damage and an expensive replacement. Even if you bought it just a month ago. This device will disconnect the battery if the voltage drops below 11.7 - 12.6 volts.
If the shutdown threshold has come, then you should approach the car, kick it on the wheel or lightly hit the hood. From this vibration, the device will restore the circuit again. And the car can be started.
That is, my battery will never deteriorate due to a strong discharge, I will not have to periodically buy them because of my carelessness. After these explanations, the neighbor got into this device from the Republic of Korea. And he said that he would buy it too. By the way, the manufacturer gives a lifetime warranty on it. They are so confident in its reliability.
I agree with you, the price is high. But "poraskinuv brains" decided that nerves are more expensive. And this device will pay off in a couple of years, especially with a lifetime warranty.
Check out the reviews, they are absolutely all positive, but surprisingly so. I bought it on the Aliexpress website. I'll leave here link. There is buyer's protection there too. I shot a video of how it works, you can watch it here.
