Advice 1: How to discharge car battery

In the yard in the hot summer, but motorists with the experience now, following popular wisdom, which refers to a sleigh and cart, thinking of preparations for winter operation. And in cold weather it is necessary to ensure the machine reliable battery.

You will need

1
A well charged battery will be able to provide energy to the starter for a successful engine start in any weather. It depends on the degree of load on the driver during the autumn-winter period. To be more precise, the ability of the battery to retain its capacity.
2
In connection with the foregoing, from the operation of the battery in summer, depends neither more nor less than its trouble-free operation in winter. Automotive generator is designed in such a way that they generated energy provides only charge the battery in the range of 70-80 percent density. And in order to recover lost capacity after each engine start by the starter, the power plant required to operate at medium speed continuously for two hours, at least. You understand that, in terms of movement of transport in the city compliance with such a regime is simply impossible.
3
The conclusion is: the battery in anticipation of winter need to nourish energy. But, oddly enough, to restore the density of the electrolyte while increasing its capacity, the unit must first be defused.
4
To achieve this task battery is removed from the car, and its terminals connected load of the electric motor or light bulb, a power of 40 watts. In the course of this process is required to periodically monitor the voltage at the battery terminals (connect a voltmeter to it). The lowest possible acceptable level of discharge is equal to 11.7 volts. In cases of overcoming it in the battery, there is an irreversible process, and can be taken for scrap.

Advice 2: How to restore a car battery

Battery not start the car? Do not rush to replace it with a new one. Follow proven tips and extend its service life for another few seasons. Do not forget to constantly maintain it after recovery.
How to restore a car battery
You will need
  • - prepared electrolyte
  • - distilled water
  • - hydrometer
  • - charger – for example, "Cedar" with the automatic cycle, eliminating overcharging
  • - desulfonema additive added to the electrolyte
  • - pipette and a small enema
Instruction
1
Most often, the battery failure displays incorrect operation. Downtime in the winter in traffic with headlights, fan, rear window heating, radio draining it so that the engine restart becomes impossible. The forgetfulness of drivers leaving for a long time on size – also lead to problems when the starter is on the car.
If he decreased capacity due to the long discharge, sulfation of the plates – to bring him back to life to help a long charge-discharge cycle.
2
"Intensive care" should start with flushing the battery with distilled water, pouring the old electrolyte. Flip and shake him out of all the garbage. And then the points:
3
To dissolve in the electrolyte the additive and pour it in a battery.
4
To connect the charger (filler tube is not spinning!) and start the charge-discharge cycle in automatic mode.
5
Cycle hold until the terminal voltage reaches to 13.8 to 14.2 volts.
6
Discharge the battery through a light bulb connected to a voltage 10, 8 volts.
7
Re-start the charge-discharge cycle, to note the charging time and charging current. Multiplying, determine the battery capacity. When you reach the nominal capacity, restoration to finish.
These operations will not only help to restore a vehicle's battery for further operation, but also learn how to deal with him in the future.

Advice 3: How to restore car battery

Most motorists rejoicing that somehow the battery has served the warranty period, get rid of him. Fast capacity loss, frequent recharging – they say they think about the impending death of the battery. Whether so it actually and is it possible to restore a car battery?
How to restore car battery
You will need
  • charger;
  • - ammonia solution Trilon B (ethylene diamine Tetra acetic acid sodium);
  • - distilled water;
  • fresh electrolyte.

In practice, artists use several ways to restore the health of the batterys. Among them, for example: recharging small current and treatment of battery packin deep discharge. These methods require near-constant human presence, and take a lot of time – up to several days.
2
Electrochemical way to restore a car batteryand carried out with the help of a special charger. The batteries are recovered in the charge of their asymmetric shock. This method allows you to recover zasulfatirovan battery batterys, and conduct preventive serviceable battery.
3
The most radical and fastest way to restore a car batteryand chemical. For chemical recovery capacity you will need ammonia solution Trilon B (ethylene diamine Tetra acetic acid sodium), which contains 2% Trilon B and 5% ammonia.
4
Before you begin to chemical recovery, fully charge the battery. Then carefully, with precautions, empty the electrode. Then rinse, preferably with distilled water for 2-3 times.

5
In carefully washed the battery pour the prepared ammonia solution of Trilon B. Leave the battery in this state for desulfatace, which will be accompanied by a release of gas and formation of fine spray. After 40-60 minutes the gas stops, which would indicate the end of the process.
6
Drain the solution and rinse again 2-3 times the battery with distilled water. Pour into the jars electrolyte standard density, and set it on charging to the nominal capacity. All. 2-3 years restored the battery will serve.

Note
In the absence of ammonia solution Trilon B, you can use acetic acid solution with baking soda.
Useful advice
With a strong sulfation of the plates, the treatment should be repeated.

Advice 4: How to work car battery

The battery is an integral part of the car. It has three main functions. First of all, the engine is started. Also need a battery to power some electric devices, such as alarm, when the engine is off. When the load on the generator is big and it can not cope, then this load is divided into the battery.

The device's battery



Car battery or rechargeable battery (battery) usually consists of 6 elements. Total voltage of battery - 12 volt. Accordingly, each element produces 2 volts.

Each element of the battery is a lead plate, which is coated with a special active substance.

The battery has negative and positive plates. The difference between them lies in the substance which they covered. Positive are usually covered with lead dioxide and the negative porous or spongy lead.

The battery capacity is filled with a special electrolyte based on sulfuric acid. Lead elements immersed in the electrolyte.

Battery life



When the battery is connected some load, it starts to produce an electric current. This is the result of chemical reaction between sulfuric acid and active material, which covered the plate.

In the process of the chemical reaction of the electrolytic solution becomes less concentrated and the plates precipitated salt, namely, lead sulfate.

The more salt deposited on the plates and the smaller the concentration of the electrolyte, the smaller the electric current produces the battery. To restore normal operation, the battery must be connected to the charger.

When the battery is charging, a chemical reaction takes place in the opposite direction. Salt is dissolved in the electrolyte, which returns its concentration, and the active material on the plates is restored.

After charging, the battery regains its ability to produce an electric current.


The failure of the battery



In principle, the battery has no elements that could break. Usually malfunctions are not associated with his own defects, and with a small charge.

The battery runs out quickly if it has the extra load during Parking retained on size or the unit, the leakage current, which is common on older cars.

Itself battery life, of course, wears out. Sooner or later the plates are subjected to corrosion, an active coating on them is depleted, the depletion of the electrolyte.

When the battery is a long time in a discharged state, the wear of its elements is much faster.

To increase battery life it should always be kept charged.


The greatest wear on the batteries when exposed to high temperatures, i.e. in summer, however, affects this wear only in winter.
