The accumulator is a device for storage of energy in a chemical form which can be used as an elektricha a stvo.

The accumulator works thanks to the fact that two various metals, being in acid solution, produce electricity.

The accumulator has absolute efficiency at 27 °C. At –18 °C 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 °C.

Starting power (starting amperes) shows ability of the accumulator to start the car in the conditions of very cold weather. It shows the number of amperes which develops the accumulator within 30 seconds at –18 °C without power failure lower than 7,2 volts (the minimum level demanded for reliable start). The this indicator, the more starting power of the accumulator is higher.

Reserve power shows time extent in minutes during which the accumulator provides 25 amperes at 27 °C. This 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 °C and below the accumulator will be badly charged in connection with increase of internal resistance. At short trips in the winter the energy spent by the accumulator for start is not compensated. As a result the accumulator works very hard, is constantly discharged and eventually, fails.

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


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

Electrolyte is very aggressive. Use protective gloves and points. Do not incline the battery – from air vents electrolyte can pour out. At hit of electrolyte in eyes immediately wash out eyes clear water within several minutes. After that immediately see a doctor. At hit of electrolyte on skin or on clothes, immediately neutralize acid alkaline soap and wash out the appropriate place a large amount of clear water. If by mistake electrolyte got in an organism, urgently see a doctor.

At a charge of rechargeable batteries explosive mix of gases is emitted.

During the work with wires and electric devices use of fire is forbidden, the sparking devices open are fire-dangerous ми light devices and smoking. It is necessary to avoid emergence of sparking at the address with wires and electric devices. Never close directly the battery plug: there is a big danger of receiving herbs we because of strong sparking.

Before carrying out any works on system of electric equipment of the car disconnect minus a wire from the rechargeable battery. When replacing glow lamps it is enough to switch off the corresponding switches.

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

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

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

Check of level of electrolyte

Arrangement of tags for check of level of electrolyte in the rechargeable battery

The rechargeable battery under normal conditions of operation of the car almost does not demand service. At high temperature of air it is recommended to check electrolyte level in the battery from time to time. Also it is necessary to check electrolyte level at a battery charge. It has to be always between the tags of MIN and MOVE put on the longitudinal parties of the battery see rice. An arrangement of tags for check of level of electrolyte in the rechargeable battery.

At decrease in level of electrolyte it is necessary to add in the relevant banks the distilled water to mark MOVE. It should be made before electrolyte falls below the mark MIN.

Do not pour electrolyte above necessary level, otherwise electrolyte will follow through an air vent. It can lead to damage of a paint and varnish covering and to corrosion of a body.

After a dolivka of electrolyte it is necessary to close densely the relevant accumulator banks traffic jams.

Operation in winter conditions

In the winter on the rechargeable battery especially big loading falls. Besides, at low temperatures the battery gives at launch of the engine only a part of that power which it has at a positive temperature. Therefore we recommend to check the rechargeable battery before a winter season and if necessary to complete charging it.

If the car at very hard frosts for several weeks is not operated, it is necessary to remove the rechargeable battery and to place it in storage to the heated room in order that it did not freeze and thereof did not collapse.

Charging of the rechargeable battery

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

At a charge small current (for example by means of the low-power charger), there is, as a rule, no need to disconnect connecting wires of onboard system of electric equipment. Anyway it is necessary to follow instructions of the manufacturer of the charger.

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

We recommend not to put on the car once any more the frozen and thawed rechargeable battery as the monoblock of the battery can have in a crack owing to formation of ice when freezing the battery.

If the rechargeable battery was disconnected from onboard network and again is attached to it

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

 – all data from the memory device of the route computer are erased;
 – all data from the memory device of memory of a driver's seat are erased;
 – hours with arrow indication stop, hours with digital indication get off;
 – the receiver installed at manufacturer is blocked;
 – automatic equipment of rise and lowering of glasses does not work with electrowindow regulators.

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

Further you should restore functioning of automatic equipment of full rise and lowering of glasses.

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

The radio receiver installed at manufacturer can be brought to the working condition only by means of input of the corresponding code – see. "Guide to use of the radio receiver".

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

Installation of the rechargeable battery

1. Install the battery on the place intended for it and fix it by a bolt.
2. At connection of the battery connect at first a positive wire (in most cases red color) and then minus a wire (in most cases black or brown color).
3. The plus plug of the battery is protected by a cover. Close a cover.

Acquisition of the accumulator

Probably, the most important what the buyer has to pay attention to, are characteristics of the accumulator. They are three. The first – rated voltage, it at all batteries identical, and it is impossible to be mistaken. Upon purchase it is desirable to check the accumulator a load fork. The second – the capacity measured in ampere/hours (A/h) means, roughly speaking, the quantity of the electric power which is kept in the accumulator. Depends on capacity as it is long possible to twist a starter the engine, more precisely – how many it is possible to make attempts to start the engine. The price of the accumulator is almost directly proportional to its capacity. And the third characteristic – starting current (it is measured in amperes, And), i.e. the current given on a starter during start-up. On accumulators it can be specified on four different systems: GOST (on domestic), EN (the standard of Uniform Europe), SAE (the American standard) and DIN. The last, German standard, is closest to our state standard specification and on the majority of the European batteries is put "by default" i.e. when the system of the standard is not specified. The it is more, the quicker and with a bigger 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 usual term and it is bad to cope with winter start. Having bought the battery even not much more to bigger capacity, you will not win in service life since constant недозаряд the accumulator will lead to sulphation of plates, and will lose in money. It is not necessary to be fond of the raised starting current also: you will burn a starter. Replace oil in the engine better, and problems with start will not be.

Lately the market of the country is overflowed with low-quality goods and fakes. Accumulators are not an exception. There are several signs on which it is possible with a sufficient accuracy to distinguish the original from a fake. The first and, perhaps, main thing: on the accumulator the country manufacturer and the releasing plant have to be surely specified, it is better if with the address. The second – date of production has to be specified that is very important if the accumulator which is filled in. Technical data sheet has to be attached to each battery, and here existence of the instruction is optional. It is connected with what in the West accumulators almost do not sell at retail, they are installed by experts at service stations. The third – the high-quality accumulator is inconceivable without качествен a leg of the case, the good traffic jams and smooth output plugs which are quite often greased with technical protective lubricant from oxidation and covered from above with color plastic caps.
