The battery does not hold charge possible causes, workarounds and recommendations

Every day we run the car and don't even think as it happens. To the engine began its work, deploys a set of systems and mechanisms. One of the most important in this chain is the battery. Without it impossible to start the engine. Over the years the battery loses its capacity. The machine begins to wind up worse. Often the owners can sometimes be a battery charge problem. Why is the battery not holding a charge? Find out in our today's article.

When to sound the alarm?

At what voltage it can be argued that the battery doesn't hold charge? The minimum value for the start of the engine is 12.5 volts.

In this case, the motor will resume operation at the first turn of the key. If this figure is less than 0.5 volts, the motor will also start, but with great difficulty. Critical is the voltage at 11 volts and less. In this case, there is a risk that the engine won't start. How many hold a charge the battery? Ideally it needs to maintain a stable value without recharging for up to three years (but under the condition of regular operation of the vehicle, as charging battery generator). If after arrival home in the evening the battery in the morning, it means that the battery is faulty. In the event of downtime she needs to stay at least one month.

Banal reasons

To Start the search problem need small. Visually inspect the contacts that go to the battery. Terminals should not have oxidations. When possible hard starting of the engine as on the hot and cold. The reason is simple – the terminals are loose fit to the terminals of the battery. Accordingly, the starter goes less inrush current.

And after running a battery can be fully charged from the alternator due to the same acid. The result is that the battery badly holds a charge and the car hard to start. Another common reason – damaged the fuses on the generator. They are metal and are located in a separate block. If these plates are open, the charge will not flow to the battery. As a result, all the appliances will get power from the battery and replenished, it will not. The solution to the problem – replacement of the fuse.

Banks

This is a more serious reason. Banks – these are the six holes that are in the Bank. Each jar contains lead plates. The latter is placed in the acid electrolyte. In the process of contacting the plates and electrolyte are accumulated electricity which is further used to start and operate the vehicle. The voltage of each Bank is approximately 2 volts. And if one of the cans will not work, the battery is charged to only 10 volts.

These elements are deteriorating for two reasons. This:

• The Evaporation of the electrolyte. How is it determined? After unscrewing the lid, you notice a low fluid level. In a certain Bank it will be less than others. But it also happens that the liquid evaporates in several compartments.
• The Shattering of the plate. In this situation, the electrolyte level may be normal. But the liquid is not transparent, but black (almost black) color.

And if in the first case the problem can be solved by adding distilled water, then with the deformation of the plates is the only way – buying a new battery. Note that battery capacity will not fall after adding distilled water. In banks it evaporates, not the acid. The latter is much heavier and stays on the plates.

- Circuit plate

Improper use may cause this phenomenon. This happens if the battery often sits in a zero. Else could be the electrolyte. But it happens, if the car often stands in the cold more than 30 degrees. To avoid freezing of the plates in strong frosts it is recommended to keep the battery warm, I mean to bring him to the house.

The Battery is not holding charge: the restoration of the plates

Some are trying to recover the battery by charging with a small current. But it will do nothing. Restores the battery in the following way. First rinses the cans with distilled water. It fills the compartment to the maximum. Then mix (in this case, you even need to flip the battery upside down) and drained. If necessary, repeat the procedure again until the holes do not go clear water, no dirt and dark tint. In some cases it is possible thus to clean the plates of the oxidized particles and to return the old battery life. But if the mud is too much, these plates can not take the charge and after 10 cycles of cleaning.

Desulfatace

If the battery will not hold a charge, maybe on the plates occurred the deposition of salts. They need to remove. For that, the shop acquired a special desulfurizers additive to the electrolyte.

Also the scaling can be done usinga special memory. The procedure of desulfuratsii is done in several steps:

• First fresh electrolyte (its density shall not be less than 1.28 grams per cubic centimeter) purchased the additive dissolves. It takes quite a lot of time – 48 hours.
• Next in jars filled with electrolyte. You should check its density. This is done using a hydrometer. This option shall not be less than 1.28 grams.

• Then twist the plastic tube in banks and connected to the battery charger. To the battery to keep charge again, we need to produce several cycles of charge-discharge. For memory you need to set the minimum current. It should be no more than one tenth of the maximum. When the battery voltage has reached 13.8 volts, you must reduce the charge current in half. Next, make the measurement of density by hydrometer. Leave the battery for two hours. Then re-do the measurements. If the density fell, so we were able to restore a dead battery.

But that's not all. We need to make an adjustment of the electrolyte. To do this, bring it to a density of 1.28, and then fill up with distilled water. This is followed by discharge of the battery. It connects a powerful lamp or a resistor and limit the current to one ampere. You need to wait until the voltage falls to 10.2 volts. Since the load need to turn on the timer. This is an important parameter during restore battery.

The discharge Time is multiplied by the discharge current. So we get the battery capacity. If it is below par, you will have to repeat the cycle of charge-discharge. And so as long as the capacity will not match factory.
