Check of a condition of the battery, care of it and charging

Address also to materials of the Head of System of electric equipment of the engine.

The storage battery is in a water modular compartment, between an impellent compartment and a windscreen.

The provided service life of the storage battery is reached only if it is always rather charged.

When using the car mainly at short distances or at long parking, we recommend to a thicket to inspect degree of a zaryazhennost of the storage battery.

Tools and materials necessary at service of the storage battery

1 — Obverse boards / goggles — at removal of traces of corrosion by a rigid brush crystallizing particles of acid easily can get to eyes.
2 — Baking soda — water solution of baking soda is used for neutralization of traces of corrosion.
3 — Acid-free vaseline — greasing of plugs of the battery will help to avoid corrosion development in the future.
4 — the Adaptation for cleaning of plugs of batteries / tips of wires — a special form shchetochny nozzles from a rigid wire will help to smooth out effectively plugs of the battery and terminal clips.

5 — the Impregnated felt washers — installation of such washer directly under a terminal clip will allow to avoid corrosion development.
6 — the Stripper — sometimes clips of wires appear are planted on plugs very densely and do not give in to removal even a full otpuskaniye of fixture.
7 — the Adaptation for cleaning of plugs of batteries / tips of wires — despite constructive difference from mentioned in point 4, is intended for performance of the same tasks.
8 — Rubber gloves — it is not necessary to underestimate the importance of this protective tool — do not forget that the battery contains sulfuric acid!

Check and leaving

At work with the battery it is necessary to undertake certain security measures. At battery banks always there is extremely an inflammable hydrogen therefore at all do not allow approach to the battery with a zazhzhyonny cigaret or other types of open fire. The electrolit of the battery represents solution of sulfuric acid which at hit in eyes or on open sites of a body causes serious traumas. Besides, acid corrodes clothes and paints. At battery shutdown always the first disconnect a weight cable, and connect it in the last turn!

Corrosion of plugs of the battery is usually shown in the form of an easy, friable powder

The wire detachment from the battery plug by means of a key - sometimes when corrosion destroyed a nut, for this procedure is required special flat-nose pliers (always the first disconnect and the last connect a weight wire!)

Irrespective of adaptation type for cleaning by result always there should be a pure, brilliant surface of the plug

When cleaning tips of wires it is necessary to remove all traces of corrosion (the internal part of a tip has a konusnost repeating a form of the plug of the battery therefore do not remove too much material)


    Care of the battery is very important procedure, allowing to avoid stops in a way because of its discharge. Performance of procedure of service needs the corresponding tool. Before the beginning of procedure of service always at first switch off the engine and disconnect all electrodevices, then disconnect a weight cable from the battery.

If the radio receiver of your car is equipped with system of protection against theft, make sure that you gathered the correct code before a battery detachment.

    Usually cars are equipped with the batteries which are not demanding special leaving. It is possible to remove covers a banok and to add the distilled water. Latest models can be equipped with the batteries which not are not demanding leaving which are completely sealed.
    Shift a cover over the storage battery to the right (arrow 1) and remove it up (arrow 2).

The storage battery with the indicator (production version)

Check electrolit level, if necessary, add the distilled water.

It is possible to determine level of electrolit and degree of a zaryazhennost of the storage battery by the indicator (shooter). Shine the indicator with a pocket small lamp. Emergence of three various flowers is thus possible:

    the green – the battery is charged sufficiently; the black – the battery is not charged or strongly discharged; colourless or yellow – low level of electrolit, it is necessary to add the distilled water.

Owing to existence of air vials under the indicator color can appear incorrect. Therefore at check knock slightly with any subject of the battery case.

If the battery has age more than 5 years and the indicator has no color, it is necessary to replace the battery with the new.

In the storage battery shine with only a pocket small lamp. By no means for this purpose do not apply opened fire (a lighter, a match). Danger of explosion! Watch that near the open case of the storage battery there was no burning cigaret.

Filling of the storage battery with the distilled water


    Switch off ignition. Remove a film over a stopper.
    Unscrew a battery stopper. HUNDRED apply a special bottle of VAS 5045 to battery filling, the design of which jellied branch pipe interferes with overflow of sections of the battery and electrolit pouring. At achievement of a maximum level intake of the distilled water in battery section automatically stops.
    If the specified special bottle available is not present, fill in water to an internal mark (a plastic crossing point) (1) or to an external label of MAX.
    Screw a battery stopper.

At all do not pour in too much the distilled water since otherwise from the battery the electrolit which damages adjacent parts will start to pour out.

The storage battery without the indicator

Check electrolit level, if necessary, add the distilled water.

Check visually electrolit level on the transparent case of the battery. Turn out a battery stopper only in that case when electrolit level in any section fell below MIN mark.

If to define level of electrolit it is impossible, turn out a stopper and look in section. Do not shine in the battery with open fire. Danger of explosion! Apply for this purpose a pocket small lamp.

Filling of the battery with the distilled water


    Switch off ignition.
    Fill each section of the battery with separately distilled water. To a mark of MAX or to an internal label (a plastic crossing point) (1).
    Screw a stopper and tighten it.

At all do not fill in too much the distilled water. At too high level of electrolit it is necessary for sucking away.

Check of reliability of plugs of the storage battery

If the battery is fixed poorly or plugs are not tightened, a consequence of it can be premature failure of the battery owing to its jolting, a cable or violation obgoraniye in electric equipment work. As at not attached batteries are erased data of electronic blocks of memory, for example, a radio receiver familiarize with instructions on removal and battery installation in the Section Replacement of the storage battery.


    Move in different directions plugs (1) and (2) of the storage battery and check reliability of their fastening. If necessary, tighten fastening nuts. Inhaling moment: 6Нм.
    If the battery is fixed poorly, fix a collar (3) bolt of fastening (4) moment 12Нм. At detection of traces of corrosion (usually representing a friable raid of white color) disconnect wires from plugs, smooth out them a special brush and again connect. Emergence of corrosion can be minimized by installation of specially processed washers which are available on sale in shops of auto parts, or by drawing on plugs and collars of wires of a layer of acid-free vaseline or suitable greasing after their connection. Make sure that the pallet of the battery is in a satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery acted in film from the pallet, track, that in an installation time on it details or other extraneous subjects did not lie. At a latching of a fixing collar do not tighten its bolt too hardly. Corrosion traces from the pallet, cases of the battery and surrounding surfaces can be removed by means of water solution of baking soda. Put a mix with a small brush, let's to it stand and then wash away plentiful quantity at its finest. The metal surfaces of the car which have undergone corrosion, it is necessary to cover with a first coat on a zinc basis and then to paint. Additional information on the battery and on engine start from an external source can be found in the Head of System of electric equipment of the engine and in Introduction.


Producers recommend to remove the battery from the car for its charging since the gas which is allocating during this procedure, can damage the painted surfaces or a car interior, depending on a battery arrangement. The fast charging with the connected wires of the battery can lead to damages of electric system of the car.


    Remove all covers about a battery banok (if they are available) and close openings pure rags to prevent an electrolit spillage. Disconnect a cable of weight of the battery and connect charger wires to its plugs (positive to positive, negative to negative), then turn on the charger in a network. If it has the switch, make sure that it is established in situation of «12 volts».

If the radio receiver of your car is equipped with system of protection against theft, make sure that you gathered the correct code before a battery detachment.

    If you use the charger with a current more than two amperes, regularly check the battery during a charging to make sure that it did not overheat. Using the slow charger, you can quietly leave the battery to be charged on all night long after regular check within the first two hours. At a charging of the batteries which are not demanding leaving, certain precautionary measures (for example, use of very nizkoamperny charger) can be demanded. On such battery can be precautionary шильдик but if it is not present address for consultation in representation office of the manufacturer or to the electrician of a repair truck. If banks of the battery have the demountable covers, each hour within the last several hours of a charging cycle check electrolit density by means of the areometer. Inexpensive areometers are available on sale in shops of auto parts - at their application follow enclosed instructions. It is possible to consider the battery charged if within two hours indicators of density of its electrolit do not change, and the electrolit in banks freely bubbles. The electrolit density in separate banks should be almost identical. If this not so, means, one or several banok of the battery failed and it is necessary to replace them. Fuller information on the battery and on engine start from an auxiliary source can be found in the Head of System of electric equipment of the engine and in Introduction.
