14.12.2. How correctly to choose the accumulator
THE GENERAL DATA

Probably, at each motorist there comes such moment when to potter further with the old storage battery begins too хлопотно. Especially if on a court yard winter also there are bitter colds. Constant problems with engine start, infinite "house" additional charges and fear that the showered active weight at the most inappropriate moment will close plates then from any crossroads you will drag home on a tow. The conclusion arises: the new accumulator is necessary. But what?

All стартерные storage batteries share on three categories: served, or maintainable; малообслуживаемые; the unattended.

Served accumulators for the present meet on sale though about ten years ago they made practically overwhelming majority. Now they are made some by the Russian factories moreover in the several countries were соцлагеря. They are easy for learning on эбонитовому to the case and black mastic which is filled in from above. Such accumulator gives the chance to replace the block of plates one or several банок if between plates there was a short circuit. But the overwhelming majority in it will not be engaged. Besides more expensive in manufacture эбонитовый the case less other, than plastic, and at blow breaks up. Mastic too has an essential lack – in due course from a dirt and temperature drops it loses the изоляционные properties, paternal the accumulator starts to be discharged spontaneously very quickly.

The owner of the unattended accumulator is simply deprived possibility something to make with it: on a cover of such battery there are no apertures and jellied stoppers. These are the special accumulators intended for defined (read – ideal) service conditions with a soft climate and the debugged service. They very expensive also approach for use not on all cars.

The majority of automobile accumulators let out all over the world is малообслуживаемыми. They have no such rigid restrictions in operation and are widely presented in the market, from rather cheap and simple to expensive, qualitative and literally larded by modern technologies.

Let's admit, you have decided to buy the accumulator, but where also what? At first – where. Is better to go to solid firm where to you will quickly pick up that is necessary. Now – what. We will not advise something concrete, we will make only some recommendations.

The prestige and popularity of any mark of accumulators have crucial importance at purchase, but it is necessary to consider and some technical moments. Certainly, the chemical compound of plates or technology of their manufacturing are hardly known to the seller. And whether it is necessary it is to the buyer? It is better to pay attention that it is possible to see most. For example, the packaged plates (each plate is packed into a microporous envelope-separator) which prevent short circuit between them owing to осыпания active weight and accordingly prolong term of "life" of the accumulator. Such packages are well visible if to open a jellied stopper. Pay attention and to stoppers. It is known that at gymnastics of the accumulator water from electrolit is evaporated and at электролизе decays on hydrogen and oxygen.

That the accumulator has not blown up, in stoppers do sideways or from above a small aperture for an exit of gases. In the most simple (and the cheapest) accumulators do simply small aperture which can quickly be hammered by a dirt. In more expensive stoppers are made like the valve which is not giving to electrolit to be splashed out, with a cavity for конценсации steams. Is better, if stoppers have no apertures, and in a battery cover there is a system of cavities for water condensation, and also uniform газоотводный the channel, as in unattended accumulators.

Maloobsluzhivaemye accumulators are delivered by manufacturers сухозаряженными (as the majority served) or filled in with electrolit at factory. If you buy the accumulator for the future it is better to buy сухозаряженный: at it the big period of storage. To result them in a working condition, it is necessary to fill in electrolit. Filled in at factory аккмуляторы are already ready to work. The electrolit for them prepares experts from high-quality components and contains much (sometimes more than twenty) the additives interfering сульфатации, осыпанию active weight, etc. It is necessary to tell that on sale there were the special modifiers ostensibly containing such additives, but they do not cause trust. There is one more advantage at the filled in accumulators. Before to get to a trading network, them subject to special gymnastics with the control of parametres on special equipment. Thus to reveal poor-quality batteries it is much easier.

Probably, the most important, on what the buyer should pay attention, are characteristics of the accumulator. Their three. The first – номанальное pressure, it at all batteries identical, and it is impossible to be mistaken. At purchase it is desirable to check up the accumulator a loading plug. The second – the capacity measured in amperes/hours (A/h), means, roughly speaking, the quantity of the electric power stored in the accumulator. On capacity depends, as it is long possible to twist a starter the engine, is more exact – how many it is possible to make attempts to start the engine. The accumulator price is almost directly proportional to its capacity. And the third characteristic – a starting current (it is measured in amperes,), i.e. A current submitted on a starter during start-up. On its accumulators can specify on four different systems: GOST (on domestic), EN (the standard of Uniform Europe), SAE (the American standard) and DIN. Last, German standard, is closest to ours STATE THAT and on the majority of the European batteries is put "by default", i.e. When the standard system is not specified. The it is more, the faster and with большей force the starter will turn the engine.

It is better, if you buy the accumulator with those characteristics which are specified in the maintenance instruction of your car: so it will serve to you longer at the minimum expenses. It is possible to save and buy the accumulator of smaller capacity, but it will serve you less than usual term and it is bad to cope with winter start. Having bought the battery even ненамного большей capacities, you will not win in service life, since. Constant недозаряд the accumulator will lead сульфатации plates, and will lose in money. To take a great interest in the raised starting current also does not follow: will burn a starter. Replace oil in the engine is better, and problems with start will not be.

Lately the country market is overflowed by the poor-quality goods and fakes. Accumulators are not an exception. There are some signs on which it is possible with sufficient accuracy to distinguish the original from a fake. The first and, perhaps, the main thing: on the accumulator the country-manufacturer and letting out factory should be necessarily specified, it is better if with the address. The second – manufacturing date that is very important, if the accumulator filled in should be specified. Characteristics sheet, and here instruction presence should be applied on each battery it is unessential. It is connected by that in the West accumulators almost do not sell at retail, they are established by experts at service stations. The third – the qualitative accumulator is inconceivable without the qualitative case, good stoppers and smooth выводных the plugs quite often greased with technical protective greasing from oxidation and covered from above with colour plastic caps.
