The battery is one of the most important details of the design of any car. All modern cars are equipped with a highly capacious battery, which supports the efficiency of all electrical systems. With the development of technologies and an increase in the varieties of electronics used in cars, the need for quality batteries has increased significantly. Now it is almost impossible to meet a single car without an acoustic system and car radio, increasingly machines are equipped with air conditioning, heated windows, mirrors and seats, as well as many others. No such element is capable of functioning normally for a long time without meals.

Mode of operation of the car battery due to changes in the outdoor temperature

Surely everyone noticed that the charge of a mobile phone in the winter is grabs substantially less than in the warm season. Also occurs with the automotive battery. At sufficiently low temperatures, the battery capacity is gradually decreasing, and the drawback of the charge may result in a complete discharge. After that, the values \u200b\u200bof the start current will not be enough to vain the starter of the car.

Operating a car battery in winter entails a number of certain requirements, since electricity consumption during this period increases significantly. In winter, the most often used heated by the side mirrors of the car, as well as the rear window. In addition, it is not necessary to do without a constantly working stove of heating salon and heating seats, it is not necessary to eliminate the used running lights and headlights. Each electrical circuit element creates an additional burden on the battery.

If you compare the efficiency of any generator and a modern battery, then in winter at a temperature of -30 degrees Celsius it will be only 3-5% of the normal charge current. And this means that it is in winter that the battery will constantly chance the charge, which means that will require additional service. It is necessary to maintain the operating temperature of the battery, warming it with special thermal insulating materials. You should not neglect the use of charging devices, thanks to which it will be possible to fully charge the battery and restore it.

Experts recommend not to forget about the battery and in the summer. If in winter in the car's car constant problem of constant insufficient charge, then in the summer heat he will suffer from lack of water. At high air and engine temperatures, the total temperature under the hood of the car is significantly increased. There will be no complaints of the battery in summer, since the activity of the flow of electrochemical processes is increasing substantially. However, this leads to a gradual electrolytic decomposition of water for hydrogen and oxygen.

Therefore, you should not forget to keep track of both the level and the density of the electrolyte in the banks of the battery. Permanent service will help to avoid premature corrosion of electrodes inside the battery and the early exit of it.

Cold launch current

The cold start current is the value necessary for the starter scrolling when it is first started, since it takes the main load on itself. From the type of starter and the engine model will depend on the required value of the cold start. So if for a passenger car in the summer it will be enough 100-150 A, then for the SUV, this indicator may increase twice. They are in summer, as well as the winter period, these indicators differ significantly. If in the summer to start the car's gasoline engine, there will be sufficient current even in 70 A, then in cold weather, the current on the same model of the machine can reach 300 A. Thus, the degree of charge of the battery has a direct effect on the cold launch current.

According to experts, one of the most disadvantaged factors for the battery are short moving by 15-20 minutes. Such moving only discharge the battery without giving it a normal charge. If such short moving will be carried out for some time, then very starting current soon for the cold start of the car will not be enough.

For residents of the metropolis, there is also a big problem that destructively affects the battery - traffic jams. In winter, heated mirrors, glasses, seats, stove, headlights and radio can be enabled in the car at the same time. Thus, the total consumption of all the devices will significantly exceed the current that is able to work out the generator at idle.

After about 40-50 minutes, with such a work, the battery charge capacity may fall to a critical level and re-start the engine will already be impossible. To restore the required capacity, it will take at least half an hour of driving in normal mode.

Battery capacity

Before buying a battery, you should deal with all its parameters and the requirements necessary for its productive work in the electrical network of the car. After all, acquiring such an important detail, we wish to get a maximum of what the manufacturer indicated on the package.

External dimensions, weight, terminal placement are not the most important battery parameters. One of the most important parameters includes the capacity of the AKB, measured in amps-hours (A / hour). This parameter is always indicated on the label and goes along with the starting current force indicator.

The battery capacity should be divided into 2 types: nominal and backup. The nominal container is the amount of electricity, given by the battery through the gradual discharge of a small current for 20 hours. The discharge current must have a value of 0.05 from the value of the specified nominal container. For example, the battery, the capacity of which is 60 A / hours is discharged with a current 3 A, and 90 A / h - 4.5 A. to the obligatory parameters of the verification indicates the stable air temperature equal to 25 degrees Celsius.

Also, an important parameter is the backup capacity of the battery. It is a reserve of the battery capacity, which is measured in minutes with a stable discharge of 25 A. This type of capacity can be equated by the movement of the car after the failure of its generator. The backup capacity of the automotive battery capacity of 55 A / h is approximately 90 minutes. This time corresponds to the time of the car movement only on the energy of the battery itself, if at the time of the failure of the generator it was charged 100%. In the calculations of the backup capacity, the headlamps and heating of the car were taken.

Lead acid accumulators, advantages and disadvantages

The battery in the car is its important and integral part. It is this small device under the hood of the car provides a normal engine launch and subsequent provision of energy of all parts of the electrical circuit. The most popular and most affordable type of batteries are lead-acid, which have already have a 150-year history. In the principle of operation of which the electrochemical reaction was laid between lead and lead dioxide, which are in acid in the form of lattices. The reaction begins only when the outer load is connected to the terminals, as a result of which an electric current is produced.

Clean lead is not used in modern battery, and various impurities include, increasing the strength of the lattices themselves and specifications. The lead-acid battery has an advantage with which no other type can compete. The lead-acid is today the only type of starter batteries, since it is that they have a high energy container. They are capable of giving a large electric current in a short period of time. It is just necessary to rotate the starter and the crankshaft of the car.

The disadvantages of this type of batteries include their harmfulness and danger, since the composition is used acid and lead.

AGM execution technology, gel batteries, dignity and disadvantages

Gel batteries and AGM technology are a variety of batteries in which the electrolyte is not in liquid form, but in gel-like. From this state of the electrolyte and the name of the type of batteries has gone.

Engineers for many decades tried to solve the issue of shuffling from lead plates of the substance and ensure the safety of batteries. From the damaged lead-acid battery could easily find the electrolyte, which is a caustic substance. Engineers came out of the situation and were able to simultaneously protect the battery from the flow of electrolyte in the event of damage, as well as to reduce the shower of the active substance from the plates. To solve these problems, the liquid electrolyte has been translated into the gel state.

In essence, gel accumulators and those that were performed using AGM technology are very similar. The only important difference is that in AGM batteries around the plates, a special porous material is used, which protects the plates from the creeping of the active substance. Thus, the batteries with sufficient maintenance can be operated much longer than ordinary lead-acid.

The advantages of gel and AGM batteries include the fact that they are not afraid of tipping and can work normally in any position. The key advantages of such AKB include their significantly high vibration resistance, as well as the ability for a long time is in an extremely discharged state. They also discharge to a minimum almost one and the same current. Such ankb is not afraid of recharge, and after re-charge, their nominal capacity is completely restored.

The lack of gel batteries includes their charge with a small current, which eliminates the accelerated charging. Since they are "afraid" of a high current, their charge is made using special chargers. Like lead acid batteries, gels are also afraid of low temperatures, since the conductivity of the current between the plates is significantly reduced.

Despite the high cost of such batteries, with quite properly used, it is possible to exploit them for 10 years. To date, such AKB is most often installed in expensive cars and motorcycles.

Battery polarity

When replacing the battery in front of the owner of the car, the question is: what polarity needs to buy AKB? Among the huge set of batteries for passenger and trucks, there are only 2 points of polarity - direct and reverse. And what kind of polarity is suitable directly for your car, you should understand and understand it. Batteries were divided into 2 types for the reason that the location of the AKB in different models of the car can differ significantly. Accordingly, the electrical wiring can also be laid differently, therefore 2 types of acb were developed.

You can figure out the polarity on the label on the battery. The reverse polarity of the ACB according to GOST is marked with a "0" digit, or the letter "R". The nomenclature may be the designation in the form of a letter "E", or "OP". If we talk about batteries with straight polarity, then they are indicated by the number "1", the letter "L", or in the nomenclature - "PP".

The second way to determine the polarity of the battery on passenger cars will be a visual inspection. For these purposes, the battery should be put in front of them so that the label looks into your side and the terminal was closer to you. Rechargeable batteries with straight polarity will have a minus terminal on the right, respectively, with reverse polarity - left.

Starting current how to measure

Starting current is one of the most important indicators in any accumulator of a modern car. It is this characteristic of the battery that shows the maximum strength of the current that can be issued by the battery during the start of the car engine. In order to start the engine, you need to create a starter and crankshaft rotation. For these purposes, high power is needed, which can be obtained due to the power of the start current. Winter launch is even more complex, because the current current must be much larger.

Starting current is a value exceeding the nominal capacity of about 5 times. Thus, if the capacity of the acb is 70 A / h, then the starting current will be equal to about 350 A. The only thing that is worth understanding - such a starting current significantly reduces the battery charge in a short period of time, because it should be given no more than 30 seconds.

In the warm regions, the start current value for passenger cars is not significantly, since the car starts literally from the starter half-trip. But in the northern regions, where a considerable time the air temperature below zero, the starting current value is very important. After all, at minus temperatures, the engine oil becomes thicker and in order to vain the crankshaft will need more effort to starter. Accordingly, the starting current should be greater.

Recently, car owners are not neglecting the value of the start current and when purchasing the battery, testing is carried out. For these purposes, special testers are used, which produce technical measurements of the battery parameters. However, the reading will not correspond to reality, since the correct measurements of the start current are carried out only in special conditions.

Top lead acid batteries, top 5 best

When choosing any product, it is often necessary to pay attention to their popularity. Since the most popular are those models that were most acquired by car owners due to their qualitative indicators.

The first place of the best lead acid batteries is occupied by Mutlu Silver Evolution 55. The Turkish manufacturer was able to release a budget model that took the leading position among competitors in its class. When developing this model, the AKB used the most modern technologies for the production of plates, which contributed to a significant decrease in the level of self-discharge. And their increased resistance to sulfate allowed significantly to increase the operation time. The capacity of this battery is 55 A / h at start-current 420 A.

Second place occupies a car battery Act (AT) 55A3. This model of the battery was released was the Irkutsk battery factory and has very important dignity - it is able to give a high starting current even in severe frosts. This is an important indicator, especially since winter in our country is very severe. A large disadvantage becomes its insufficiently large battery capacity, because with a faulty generator it will not work far.

The third place was taken by the Battery Beast (SV) 60AZ, which is also produced in Irkutsk. Modern design, ergonomic and comfortable handle have become unusual for the domestic manufacturer. However, the capacity of 60 a / h and the maximum starting current of 467 A has become an excellent marketing move to get out of the top three among their strong competitors.

In fourth place is the battery of the Russian manufacturer Tyumen Battery Standard. Among the budget batteries, it will become an excellent acquisition of the battery for a new car. Starting current can reach 500 A, which will make it great to start the engine even with thick butter.

The honorable fifth place occupied Akb Tornado 55 A / h. The cheapest among its competitors in the market, but at the same time I was able to collect quite a lot of positive feedback about your work. This battery does not tolerate severe frosts and does not like deep discharges that in some cases it will be not very nice for its owner.

The best gel batteries, top 5 best

The best gel battery can be called Optima Yellow Top 55 AH. It was he who was recognized as the benchmark among all gel batteries. Plates in this battery are stacked by spirals. Such an unusual decision was made by the company's engineers, and the technology itself was later patented by the manufacturer. Due to this, the batteries have become more compact and have an original view with round banks. Starting current reaches 765 A and is capable of rapid high current recovery.

The second place is occupied by Vimar BG55-12 12V 55AH battery. This model of the battery is perfect for a passenger car, and for a large number of reviews, it boldly takes second place among the best.

In third place is a gel battery Luxeon LX12-60G. Capacities The battery is enough to install it in any modern car, and the starting current will allow easy launch even in the coldest winter. The main advantages is its long service life.

Fourth place - Toyama NPS50-12. This Japanese manufacturer was able to really excellent build quality and reliability. Despite the high cost, they were able to assemble a large number of positive feedback for the maximum short time in the market.

The fifth place occupies an Akb from the Chinese manufacturer Santakups FCG 12-100. The nominal capacity of this battery is 100 A / h, and one of the advantages was the complete absence of maintenance. In this model, protected from a complete discharge, and the self-discharge is practically not observed.

Best AGM, Top 5 Best

First place among AGM battery takes an eminent Bosch manufacturer.

The main advantage of Bosch 5951 is its durability to a long-term discharge of a small current, as well as to the self-discharge. Specially designed technology allows you to dial the charge for a short period of time.

The second place is occupied by Kaynar Bars Premium 60 Ah, which was produced in Kazakhstan.

The capacity of 60 A / h and the starting current of 600 and at a low cost allowed me to be embossed in the sales leaders. The disadvantages include the poor stability of this battery to frost.

Third place - Tudor AGM. 60 a / h Rated capacity of this battery, and the starting current was reached in 680 A, which is a very high indicator.

Unfortunately, for a good launch of the car in winter for any battery, only 300 A is sufficient, everything else is an excellent marketing solution to increase the attractiveness to its brand.

Austrian Battery Banner Running Bull ranked fourth.

Starting current of this model 640 A, and a nominal capacity of 60 A / h. The disadvantages of this model include the fact that in winter it significantly reduces its characteristics. The advantages of this model include excellent Cokotdach for the warm season.

The fifth place took the battery also by the Austrian company Banner Power Bull.

The manufacturer claimed a capacity of 63 A / h, at a starter current 600 A. This battery with ease ranked 5th due to a large number of fans who marked its price and quality ratios.
