How to recover car batteries
Car batteries degrade because the lead sulfate that covers the plates is coming off. One way to recover them would be to wash the glass with hot water, trying to remove the deposits at the bottom of the glass.
Then restore the electrolyte and proceed to the formation of the plate with a slow charge of 48 hours. The electrolyte must be made with distilled water and sulfuric.
Steps to recover car batteries
Clean the battery terminals. Put on protective glasses. Then, put the cleaner on each post. Turn it back and forth until the positions are radiating.
Check the battery voltage. Place the first terminal of the voltmeter on the positive terminal and the second on the negative terminal. If the voltmeter reads less than 12 volts, at least one of the battery cells is terrible.
Take off the top cover. Use a screwdriver to pry up one edge of the lid gently. Remove the lid and set it aside.
Check the cells. Place one of the voltmeters leads on the battery's positive terminal and the other on the cell. If the voltmeter reading is less than two volts, that cell has a problem.
Perform a load test. To do this, first, connect the load meter to the battery's positive terminal and then to the negative terminal. This way, you will avoid sparks. Turn on the meter and check that the load does not drop below 10 volts.
Perform a hydrometer test. Depress the hydrometer bulb and dip the tube into one of the battery plates. Observe the color of the fluid extracted from the bulb. The green color means the battery is in good condition; the white is in fair condition; the red needs to be changed. Ensure the electrolyte fluid covers at least 1/8 inch of the marked mark on each cell.
Add the necessary chemicals to the battery. To do this, follow the chemical manufacturer's instructions. Replace the plates and charge the battery with a car battery charger for no less than 24 hours.
Tips for recovering car batteries
You take out the acid from the battery, buy sodium bicarbonate, the purest, and put the bicarbonate (powdered) in each glass of the storm, approx. Three tablespoons per glass, add hot water, and you will see how each glass begins to bubble, complete with water until it covers the plates completely.
When it stops bubbling (the action of the bicarbonate on the plate), you leave it for about 20 minutes and pour the water from the battery into a pan so that you can see the residue from the containers.
Then you repeat the process with clean water several times until it comes out without residue.
Empty the battery; this work is exhausting, due to the weight of the storm, without hitting it, since you can break some plate union and let it dry well, this is important!
When you're sure it's dry, add acid again... it's sold at battery houses, buy acid (I think it was 1260) for batteries, which already has "density".
Add it to each glass until it covers the plate, do not pass it too much.
Leave it for a few hours, and then measure the charge, and oh, surprise! it is charged………if this does not happen…..there may be a disconnected glass; if so, and the battery is not "plastic", they are fixed, and they are "new."
This system has been used for a long time to clean the batteries of the lead residue deposited at the bottom of it due to the work of the battery itself.
This residue causes the plates to be in contact (making a bridge) at the bottom of its container, causing a loss in the performance of the leaves, generating their replacement; the electrolyte density depends on the charge you have.
Customs make us change batteries every two or three years as if it were a "technological barrier" that no one wants or can overcome.
The reality is quite different, and the battery itself, the plates, are only dirty; it is as if we had to change the engine every time the spark plugs wear out.
The matter is planned to produce and recycle, nothing more than those who do the "work"; they are the same ones who sell them to you.
Used batteries have a price, but for convenience, and sometimes, out of ignorance, one leaves them where the new one was bought. That guy doesn't throw it away because he knows it's the next battery.
Over time, these plates wear out, and it is there that the damaged vessels are replaced,….. as it was before, with the "tar lid" batteries; they were recycled, although that term was still little known in that epoch.
Remember that to carry out the different processes mentioned above, and it is essential to cover your eyes and hands. If you have any inconvenience, you can buy a portable car starter.
