How to use a light bulb to restore charge to an old battery

Most motorists have had a “tired” battery in their garage for more than a year. It seems to hold a charge, but loses it quickly under load. Especially in the cold. But wait to hand over the “old man” for recycling – even such a battery will still live. And about how to “cheer up” her, the AvtoVzglyad portal tells.
In the way we’ll talk about, you can’t “wind up” an overused “battery”. But the one that is 3-5 years old is very real. As a rule, the capacity of such devices is already greatly underestimated. This is done by the so-called sulfation of the plates. To check them, simply unscrew one of the plugs (this cannot be done on a maintenance-free battery) and shine a flashlight into the hole. If you see a white layer, know that the process is in full swing. In the end, he will “finish” an expensive spare part. And so that this does not happen, we apply our grandfather’s method.
First you need to measure the voltage at the terminals. They do this with a simple device called a multimeter. A fully charged battery should have 12.7 volts. Everything below is underloaded.
To revive our ward, we need an ordinary household lamp with a cartridge, wires, two clamps, electrical tape and a plug (it has nothing to do with food), which we plug into an outlet. Now we build an electrical circuit to connect the battery to a 220 volt network through a light bulb. The “shine” in this case is necessary to limit the current with its resistance. Pay close attention to the twists of the wires: they must be insulated, otherwise you could get a serious electric shock. And it can even lead to death.
Then connect the terminals to the terminals. Note that the polarity does not matter as there will be an alternating voltage. You also don’t have to worry about a short circuit – the light bulb will limit the current due to its resistance.
After the process has started, it is necessary to regularly check the temperature of the battery case. When the plastic starts to heat up, the charge goes away. But there is a nuance. You cannot leave this whole structure unattended and the heating needs to be arranged. When heat comes out of the body, you need to stop the procedure. It’s hard to say in time. Some batteries take a few hours to charge, others take a day.
In the end, we note that if the electrodes are very worn inside, then this method will not help. The spare part is only accepted by collection points.
