How To Fix A Battery

All the cars in the world, in order to start their engines, need a battery or a current accumulator. These are designed for each type of car, depending on the space they have inside their hoods.

Each car needs a number of amps, these are determined by the battery models, to have optimal operation. In addition, it also varies by the amount of voltage they can supply, this being generally 12 volts.

These batteries are composed of basic materials; such as lead, plastic, sulfuric acid and water. Plastic is the material with which the container is made, or the structure of the battery both outside and inside. Lead is on the inside of the battery, and is used to make the plates or cells that produce electricity.

Sulfuric acid and water; When in contact with the lead cells, they produce a chemical reaction called electrolysis. Electrolysis is what produces the electric current, and the amperes that are the strength of the battery.

Each cell or sheet of lead has very thin plastic separators on its sides; these are to prevent the battery from being shorted internally. It is important to know all this in a clear and simple way to be able to repair or restore the car battery effectively.

On the other hand, in Spain batteries are recycled, and all the materials they have are used to make new batteries, including the acid they have internally. At present, less heavy batteries have been designed, such as; lithium ion, cadmium, metal-hydride and others. On the other hand, the least polluting batteries to the environment are lead batteries.

However, lead continues to be a poisonous and polluting element; but most lead batteries go back to the factories to produce more new batteries. This procedure does not happen with other types of batteries that are much more polluting for the environment.

Lead batteries or accumulators; They are designed to have a useful life time, this depends on the thickness with which the lead cells are designed, which they have inside. Generally, when a battery stops producing voltage, it is because the lead in the cells has dissolved due to electrolysis; and the wear that sulfuric acid produces on lead.

Sometimes the sediment from the waste lead, which accumulates in the lower part of the battery, also prevents good electrolysis from taking place; thus, the battery is placed with a low output of voltage and amperes. This can be solved by doing good maintenance, which we will explain later.

Next, we will give you several techniques to fix a battery easily and simply in your own home.

Instructions to fix a battery

1. The batteries when buying them; They tell you how many amps your car needs to run optimally.
2. If they inform you that the battery is designed to last 3 years; and at 2 years it begins to fail you should review the following.
3. First, visualize at the top of the battery; in each group of cells they have a stopper or lid.
4. Remove any caps or caps from the top of the battery and check the acid level.
5. Battery acid level; They have to be above the lead cells by at least one centimeter.
6. If you notice that the cells are with a lower level of acid, buy a bottle of sulfuric acid for batteries in the market.
7. You have to order it for batteries; Since it comes mixed with a quantity of water, it needs to make a good electrolysis.
8. If you add sulfuric acid alone; the chemical reaction will not work well and the energy production will be low.
9. After checking this level in all the holes in the battery, proceed to add the amount of acid you need in all the holes, trying to get them all to the same level.
10. Subsequently, place the plugs or covers and place the battery to be charged with a slow charge charger for 4 hours.
11. After 4 hours; place it in your car and go!

Other techniques

1. Remove the caps from the top of the battery and check the sulfuric acid level.
2. If the level is normal; above the cells in all the holes, then take a large plastic container.
3. Place the battery in the plastic container, with the holes facing down, this is to clean out all the sulfuric acid.
4. You have to do this with safety gloves, a protective mask for your face, a mouth cover with a filter and a suit made of synthetic material and insulator of chemical products.
5. Remember that the acid in contact with the skin; causes great irreversible damage.
6. After the battery is without acid, you must place a hose with water at a low price in each hole, for several minutes.
7. This procedure is to finish removing the lead sediment from the bottom of the battery, and leaving it as clean as possible.
8. Then put the battery in the sun; with the holes facing downwards, so that it throws out all the water and dries well for 5 hours.
9. Being dry, add new battery acid, which is about two liters.
10. Remember that this must have the same level in all groups of cells, and 1 centimeter above the cells.
11. At the end of this procedure, you should place the battery on the trickle charger for 4 hours.
12. At the end of its slow charge, you can place it in the car and test its operation.

If this procedure does not work and your battery continues with a low electrical charge. It is because the lead cells disintegrated ; due to electrolysis wear. This usually starts with the group of cells on the negative terminal of the battery.

But do not worry, this also has a solution; using another battery of the same make and model using the following techniques.

More procedures to repair the battery

1. Take two identical batteries (that are bad), one of them you are going to uncover the upper part of the cell group on the negative terminal side.
2. This can be done with a small emery and using a fine cutting disc.
3. Each group of cells are connected inside the battery by a thick lead base.
4. You are going to separate this from the next group of cells with the fine-cut emery, to be able to remove that group from inside the battery.
5. When you remove the group of cells you will notice that most of the lead sheets are broken.
6. Subsequently, you go to the battery that you have as a spare; Take a group of cells from the negative side of the terminal, but from those that are more, towards the center of the battery.
7. This is because these are the ones that suffer less wear than lead cells.
8. Place the group of good cells in the battery to be repaired.
9. You must verify that the thin plastic separators, which are placed in the middle of the lead cells, are not broken.
10. If they are broken, replace them with good ones; this to prevent that group from short circuiting.
11. Then, with a high performance synthetic glue; Replace the plastic cover on top of the battery.
12. This must be done with a good amount of glue; to prevent battery acid from leaking out later.
13. Finally, place your battery on the slow charger for 4 hours and voila, new battery again.

What do you need to fix a battery?

• Two batteries of the same model that are bad.
• Battery acid.
• In fine cut emery.
• Large plastic containers.
• Hose with water at a low price.
• Special synthetic glue.
• Slow battery charger.
• Safety glasses.
• Synthetic suit for chemicals.
• Safety gloves.
• Safety mouth cover with air filter.

Tips for fixing a battery

1. We recommend that you be very careful with these procedures with sulfuric acid, which is very bad for the skin.
2. If you get a drop of battery acid in your eyes, you must quickly pour plenty of clean water, otherwise you will lose your sight forever.
3. In this type of repair, you must take safety regulations into account, to work in the best way and not suffer consequences.
