1.32. The storage battery

THE GENERAL DATA

The accumulator is a device for energy storage in the chemical form which can be used as электриче ство.

The accumulator works thanks to that two various metals, being in an acid solution, develop an electricity.

The accumulator possesses absolute efficiency at 27 S.Pri–18 about efficiency of the same accumulator falls to 40 %. Now to start the engine, it is necessary to have more than twice more energy, than it was necessary at 27 With.

Starting capacity (starting amperes) shows ability of the accumulator to start the car in the conditions of very cold weather. It shows quantity of amperes which develops the accumulator within 30 seconds at–18 With without a power failure more low 7,2 volt (a minimum level demanded for reliable start). The above this indicator, the more starting capacity of the accumulator.

Reserve capacity shows extent of time in minutes during which the accumulator provides 25 amperes at 27 with S.Etot the factor represents time during which the accumulator ensures functioning of all auxiliary devices in the car at night and in the conditions of bad weather at the faulty generator of a charge.

In winter conditions at–18 With and more low the accumulator it will be bad to be charged in connection with increase of internal resistance. At short trips in the winter the energy spent by the accumulator on start, is not compensated. As a result the accumulator works on deterioration, is constantly discharged and eventually, refuses.

In summer months after long trips the engine strongly heats up, and often happens that it is difficult for starting anew. Such "hot starts" sometimes demand as much capacity, how many and at cold weather, or it is more. It especially extends on высококомпрес сионные engines with the big working volume and cars with conditioners. It once again underlines importance of a correct choice of the accumulator according to the car engine.

The prevention

It is necessary to work in goggles. It is impossible to suppose hits of drops of acid and the particles containing connections of lead, in eyes, on a skin or on clothes.

The electrolit is very aggressive. Use protective gloves and points. Do not incline the battery – from ventilating apertures the electrolit can pour out. At electrolit hit in eyes immediately wash out eyes pure water within several minutes. After that immediately address to the doctor. At electrolit hit on a skin or on clothes, immediately neutralise acid alkaline soap and wash out a corresponding place a considerable quantity at its finest. If by mistake the electrolit has got in an organism, urgently address to the doctor.

At a charge of storage batteries the explosive mix of gases is allocated.

At work with wires and electric devices using fire, the sparking devices opened пожароопасны ми by light devices and smoking is forbidden. It is necessary to avoid occurrence искрения at the reference with wires and electric devices. Never close directly battery plugs: there is a big danger of reception of grasses we because of strong искрения.

Before carrying out of any works on system of an electric equipment of the car disconnect minus a wire from the storage battery. At replacement of lamps накаливания it is enough to switch off corresponding switches.

At a detachment of the storage battery from the onboard electric system of the car disconnect at first minus a wire, and then плюсовой. At the working engine it is impossible to disconnect the battery as, electronic devices of system of an electric equipment otherwise will be damaged.

At battery installation on the car it is necessary to connect at first плюсовой a wire, and then – minus.

That the case of the storage battery to protect from influence of ultra-violet radiation, it is not necessary to store the battery at a direct daylight.

Check of level of electrolit

Arrangement of labels for check of level of electrolit in the storage battery


The storage battery under normal conditions car operation almost does not demand service. At an air heat it is recommended to check from time to time electrolit level in the battery. Also it is necessary to check electrolit level at a battery charge. It should be always between labels MIN and a MOVE, put on the longitudinal parties of the battery, fig. the Arrangement of labels for check of level of electrolit in the storage battery see.

At decrease in level of electrolit it is necessary to add in corresponding banks the distilled water to a mark the MOVE. It should be made before the electrolit will fall below mark MIN.

Do not pour electrolits above necessary level, otherwise the electrolit will follow through a ventilating aperture. It can lead to damage of a paint and varnish covering and to body corrosion.

After доливки electrolits it is necessary to close densely corresponding storage banks stoppers.

Operation in winter conditions

In the winter on the storage battery especially big loading falls. Besides, at low temperatures the battery gives at engine start-up only a part of that capacity which it has at positive temperature. Therefore we recommend to check up before the beginning of a winter season the storage battery and if necessary дозарядить it.

If the car at very strong frosts throughout several weeks is not maintained, it is necessary to remove the storage battery and to place it in storage in a heated premise that it has not frozen and thereof has not collapsed.

Gymnastics of the storage battery

Before a charge it is necessary to switch off ignition and all consumers of a current.

At a charge a small current (for example by means of low-power зарядного devices), are not present, as a rule, necessity to disconnect connecting wires of onboard system of an electric equipment. In any case it is necessary to follow instructions of the manufacturer зарядного devices.

Before the accelerated charge that means a charge the big current, is necessary both wires connecting the battery with onboard system of an electric equipment from the battery to disconnect.

We recommend not to put any more on the car once the frozen and thawed storage battery as the battery monoblock can have in a crack owing to ice education at battery freezing.

If the storage battery has been disconnected from an onboard network and again attached to it

When you disconnect the battery from an onboard network, keep in mind that:

 – All data from a memory of the routeing computer is erased;
 – All data from a memory of memory of a driver's seat is erased;
 – Hours with стрелочной indication stop, hours with digital indication get off;
 – The receiver established on manufacturer is blocked;
 – Automatics of lifting and lowering of glasses with электростеклоподъемниками does not work.

After connection of the storage battery to an onboard network you should establish anew hours as with стрелочной, so with digital indication.

Further you should restore functioning of automatics of full lifting and lowering of glasses.

Besides, you should initialize anew memory of a driver's seat, differently there will be no storing of adjustments.

The radio receiver established on manufacturer can be resulted in a working condition only by means of input of a corresponding code – the Management on using a radio receiver "see".

Removal of the storage battery

PERFORMANCE ORDER

1. Before battery removal switch off ignition and disconnect all consumers of a current. 2. For battery removal at first disconnect those minus a wire (in most cases black or brown colour). 3. The pljusovaja plug of the battery is protected by a cover. Cast away a cover and then disconnect плюсовой a wire (in most cases red colour). 4. Turn away fastening of the battery and take out it.

Installation of the storage battery

PERFORMANCE ORDER

1. Establish the battery on the place intended for it and fix its bolt. 2. At battery joining connect at first плюсовой a wire (in most cases red colour) and then minus a wire (in most cases black or brown colour). 3. The pljusovaja plug of the battery is protected by a cover. Close a cover.

Accumulator acquisition

Probably, the most important, on what the buyer should pay attention, are characteristics of the accumulator. Their three. The first – rated voltage, 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 качествен ного cases, good stoppers and smooth выводных the plugs quite often greased with technical protective greasing from oxidation and covered from above with colour plastic caps.
