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

Address also to materials of the Head of System of an 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 in the event that it is always charged enough.

At using the car mainly on short distances or at long parking, we recommend to a thicket to inspect degree заряженности the storage battery.

Tools and the materials necessary at service of the storage battery

1 — the Obverse board / goggles — at removal of traces of corrosion by a rigid brush crystallising particles of acid can easily get to eyes.
2 — Baking soda — the water solution of baking soda is used for neutralisation of traces of corrosion.
3 — Beskislotnyj vaseline — greasing of plugs of the battery will help to avoid corrosion development in the future.
4 — the Adaptation for зачистки plugs of the battery / of tips of wires — the special form щеточные nozzles from a rigid wire will help to smooth out effectively plugs of the battery and клеммные clips.

5 — the Impregnated felt washers — installation of such washer directly under клеммный the 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 full отпускания fixture.
7 — the Adaptation for зачистки plugs of the battery / of tips of wires — despite constructive difference from mentioned in point 4, is intended for performance of the same problems.
8 — Rubber gloves — it is not necessary to underestimate the importance of the given protective means — do not forget that in the battery sulfuric acid contains!

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 suppose approach to the battery with the lighted cigarette or other kinds of open fire. The battery electrolit represents a 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 switching-off always the first disconnect a weight cable, and connect it in last turn!

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

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

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

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


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

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

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

The storage battery with the indicator (production version)

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

On the indicator (marksman) it is possible to define level of electrolit and degree заряженности the storage battery. Shine the indicator with a pocket small lamp. Occurrence of three various colours is thus possible:

  • Green – the battery is charged sufficiently;
  • Black – the battery is not charged or strongly discharged;
  • безцветный or yellow – low level of electrolit, it is necessary to add the distilled water.

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

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

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

Filling of the storage battery with the distilled water


  1. Switch off ignition.
  2. Remove a film over a stopper.
  1. Turn away a battery stopper. HUNDRED apply special bottle 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 receipt of the distilled water in battery section automatically stops.
  1. If the specified special bottle available is not present, fill in water to an internal mark (a plastic crosspiece) (1) or to external label MAX.
  1. Screw a battery stopper.

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

The storage battery without the indicator

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

Check up 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 has fallen below mark MIN.

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

Filling of the battery with the distilled water


  1. Switch off ignition.
  1. Fill each section of the battery with separately distilled water. To mark MAX or to an internal label (a plastic crosspiece) (1).
  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, обгорание a cable or infringement in electric equipment work. As at not attached batteries are erased the data of electronic blocks of memory, for example, a radio receiver familiarise with instructions on removal and battery installation in Section Replacement of the storage battery.


  1. Move every which way plugs (1) and (2) storage batteries and check up reliability of their fastening. If necessary, tighten fastening nuts. The inhaling moment: 6Нм.
  1. If the battery is fixed poorly, fix a collar (3) bolt of fastening (4) moment 12Нм.
  2. At detection of traces of corrosion (usually representing a friable touch of white colour) disconnect wires from plugs, smooth out their special brush and again connect. Corrosion occurrence can be reduced to a minimum by installation of specially processed washers which are available on sale in shops of autospare parts, or by drawing on plugs and collars of wires of a layer бескислотного vaseline or suitable greasing after their connection.
  3. Make sure that the battery pallet 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 зажимании a fixing collar do not tighten its bolt too hardly.
  4. Traces of corrosion from the pallet, cases of the battery and surrounding surfaces can be removed by means of a water solution of baking soda. Put a mix a small brush, allow to it to stand and then смойте plentiful quantity at its finest.
  5. Metal surfaces of the car, подвергшиеся corrosion, it is necessary to cover with a first coat on a zinc basis and then to paint.
  6. The additional information on the battery and on start of the engine from an external source can be found in the Head of System of an electric equipment of the engine and in Introduction.


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


  1. Remove all covers with банок batteries (if they are available) and close apertures pure rags to prevent an electrolit spillage. Disconnect a cable of weight of the battery and connect wires зарядного devices to its plugs (positive to positive, negative to negative), then include зарядное the device in a network. If it has the switch, make sure that it is established in position «12 volt».

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

  1. If you use зарядным the device with a current more than two amperes, regularly check the battery during gymnastics to make sure that it has not overheated. Using slow зарядное the device, you can easy leave the battery to be charged on all night long after regular check within first two hours. At gymnastics of the batteries which are not demanding leaving, certain safety measures (for example, application very much низкоамперного зарядного devices) can be demanded. On such battery can be precautionary шильдик but if it is not present address for consultation in representation branch of the manufacturer or to the electrician of a repair truck.
  2. If battery banks have the demountable covers, each hour within last several hours зарядного a cycle check density of electrolit with the help ареометра. Inexpensive ареометры are available on sale in shops of autospare parts - at their application follow applied 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 the several банок batteries have failed also them it is necessary to replace.
  3. Fuller information on the battery and on start of the engine from an auxiliary source can be found in the Head of System of an electric equipment of the engine and in Introduction.
