The storage battery - the general information, condition check, replacement, storage and commissioning

Information on service and charging of the storage battery is provided in Head Routine maintenance.

General information

The 12-voltny storage battery established on the car consists from six banok, containing positive and negative plates (ламели), lowered in solution of sulfuric acid. The problem of the battery includes current production for start of the car, ignition, lighting, and also for other consumers of the electric power.

The battery possesses 100 percent efficiency at air temperature 27°С. At temperature - 18°С efficiency falls to 40 percent, - start of the engine will demand twice more energy, than is spent at 27°С.

The starting capacity (starting current) shows ability of the accumulator to start the engine in the conditions of very cold weather. It is accepted to understand as this characteristic a current in amperes which the battery is capable to give within 30 seconds at air temperature - 18°С without power failure lower 7.2 In (the minimum level demanded for reliable start). The this indicator, the more starting capacity of the accumulator is higher.

The reserve capacity shows time in minutes during which the battery gives a current force 25 And at temperature 27°С, i.e. time during which the accumulator ensures functioning of all auxiliary consumers of the electric power of the car at night and in the conditions of bad weather at the faulty generator.

In winter conditions at air temperature - 18°С and below efficiency of additional charge of the battery sharply falls in connection with increase of internal resistance. At short trips in the winter the energy spent for start, is not restored, therefore the battery starts to work very hard, eventually, completely spending the charge.

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, and sometimes even it is more. In a special measure the told belongs to vysokokompressionny engines with large working volume and the equipped conditioner of air to models.

Told once again emphasizes importance of correctness of a choice of the battery according to the requirements shown by the engine established on the car.

Check

 PERFORMANCE ORDER

  1. Disconnect both wires from the battery.

The negative wire always should be disconnected first of all and be connected in the last. If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for equipment introduction in action!

  1. Check electrolit level in the battery (concerns only the needing batteries equipped with demountable covers service) - the electrolit should hide completely ламели, otherwise in banks the corresponding amount of the distilled water follows. DO NOT POUR, - surplus of electrolit at an excessive charging of the battery will start to be poured through edges of mouths! By means of the areometer (ask in shops of automobile accessories) measure specific weight of electrolit. Remove covers from jellied mouths and take away the areometer electrolit test serially from each of a battery banok. Following instructions of manufacturers, on the provision of a measuring float of the device define specific weight of electrolit. At normal level of a charge specific weight of electrolit should make 1.270 units (a green zone of a measuring scale). At excessively low density of electrolit (a red zone of a scale) the battery should be charged (see. Head Routine maintenance). Batteries not needing service are usually equipped with the special color indicator. When the spot in an observation port of the indicator gains black color, it is necessary to make a battery charging immediately. Having finished with check of density of electrolit, it is necessary to make measurement of target tension of the battery by means of the digital voltmeter.

Measurement of target tension of the disconnected battery by means of the voltmeter

 PERFORMANCE ORDER

  1. Before voltmeter connection it is necessary to remove a superficial charge from the battery, - approximately for 10 seconds include a driving beam, then disconnect everything onboard consumers of the electric power and wait about two minutes. At the switched-off engine and the disconnected consumers of the electric power connect black щуп the voltmeter to the negative plug of the battery. Red щуп connect to the positive plug. Target tension of the battery should make 11.5 — 12.5 In, depending on ambient temperature

The nominal rate of density of electrolit is defined depending on ambient temperature (and it is directly proportional to it), - use the map of temperatures delivered by manufacturers in a set to the battery.


At positive results described above checks need for battery testing under loading (see below) disappears.


More exact check of a condition of the battery can be made by means of a universal measuring instrument (ask in shops of automobile accessories). The device allows to define ability of the battery to a provorachivaniye of a starter and food giving to onboard consumers of the electric power at raised loads of the engine. Connect a measuring instrument to battery plugs. Follow instructions of manufacturers of the device - at 15-second inclusion of loading tension of the battery should not fall below, than to value 9.6 In, otherwise it is necessary to replace the battery.


At ambient temperatures below 0°С the minimum admissible indication decreases to 9.1 Century.

Replacement

Battery shutdown

The negative wire is always disconnected first of all and connected in the last!

On the car some systems demanding continuous power supply are established. Shutdown of the storage battery is led inevitably to deleting of the control system which was stored in memory by the engine by information on optimum settings, shutdown of hours, destruction of the security code entered into a radio receiver, etc. Before making battery shutdown attentively familiarize with the recommendations provided below:

  • On the models equipped with the uniform lock, do not forget to take from the lock of ignition and to put in a pocket a key, - at connection of the battery there will be an automatic locking of all doors.
  • Shutdowns of the battery will lead to deleting from memory of ECM of all turned-out adjusting parameters (except base installations). Number of such parameters treat: size of turns of idling, maximum frequency of turns and codes of malfunctions of system of self-diagnostics. Before shutdown of the battery make reading diagnostic (see. Electronic control system of ignition (and injection) petrol engines). After connection all lost turned-out settings will be restored automatically, however for this purpose the control system will need some time during which the engine can unstably work in various modes. For acceleration of process of restoration, start the engine and warm up it to normal working temperature on single turns, then for 2 minutes lift frequency of rotation of the engine to 1200 rpm then make a short trip (about 7 kilometers), constantly changing power setting, - as a result all settings should be restored.
  • If the storage battery was disconnected at the switched-on anticreeping alarm system, the system remains in the same mode and after battery connection, - at the corresponding complete set told equally treats also a regular immobilizator of the engine.
  • On the models equipped with the traveling computer shutdown of the battery will lead also to removal of all user data brought in use the computer.
  • If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for equipment introduction in action. Details of introduction of a code and the instruction on using a radio tape recorder are given in Head the Operation manual. In case of loss of a combination address for the help to specialists of firm car repair shop Opel.

To avoid unpleasant consequences of shutdown of the storage battery it is possible by means of the external power supply, - detailed instructions for use are usually provided by similar devices in the instruction on their operation. As a rule, such power supplies are connected to a lighter nest then the regular battery can be quietly disconnected. A current developed by a source should suffice for a food of memory of the module of management, prevention of blocking of a radio tape recorder and preservation of operability of hours.

Some of similar devices can submit to system a current, sufficient for normal functioning and other consumers of energy. Before service of components of electric equipment make sure that the corresponding consumer is completely disconnected!

Acquisition of the new battery

Probably, the most important, on what the buyer should pay attention, are performance data of the battery. Such characteristics 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 battery a loading fork.
  • The second - the capacity measured in ampere/hours (Ach — And/h), and, roughly speaking, defining quantity of the electric power reserved in the battery. On capacity depends, as it is long possible to turn the engine a starter, more precisely, - how many it can be made attempts of start of the engine. The battery price mainly is defined by its capacity.
  • And the third characteristic - a starting current (it is measured in Amperes), i.e. a current submitted on a starter at start of the engine. This parameter can be specified on batteries in four various ways: according to requirements of domestic standards (GOST), for standards of Uniform Europe (EN), for the American standard (SAE), or for a German standard (DIN). The DIN standard is closest to domestic state standard specification and on the majority of batteries of the European production is used "by default", i.e. without the indication of system. The size of a starting current, the is higher quicker and with higher torque the starter will turn the engine.

It is most correct to get the battery with those characteristics which are specified in the car maintenance instruction: so, - in this case it will serve more long and with the minimum expenses. It is possible to get for reasons of economy the battery underestimated against demanded in the capacity, it however will serve less and will bring much more efforts at cold starts in a winter season. Acquisition of the battery bigger in comparison with nominal capacity does not give a prize on term of its service since constant недозаряд will lead to a sulfatatsiya of plates. Battery use with excessively high starting current is fraught with burning of windings of a starter, - is much more effective in fight against the complicated starts elementary replacement of impellent oil is.

Lately the market of the country is overflowed with the poor-quality goods and fakes. Storage batteries are not an exception. There are some signs on which it is possible to distinguish with rather high precision the original from a fake. The first and, perhaps, main thing: on the battery the country manufacturer and letting-out plant should be surely specified, it is better, if with the address. The second: the date of issue should be specified that in a special measure treats batteries of the tight not needing service. Technical data sheet, and here existence of the instruction should be applied to each battery it is unessential. It is connected with that in the west of the battery almost do not sell at retail, - they are established by experts at car repair shops. The third: the high-quality battery is inconceivable without the high-quality case, good jams and the smooth vyvodny plugs quite often covered by special greasing for protection against oxidation and covered from above with color plastic caps.

Removal and installation

Before a battery detachment attentively familiarize with the recommendations provided above.

Removal

 PERFORMANCE ORDER

  1. The battery is established in the left forward corner of an impellent compartment and on some models can be placed in a protective casing.
  1. At the corresponding complete set open a cover of a protective casing, weaken a nut of a terminal tip and disconnect from the polar plug a negative wire.

    Scheme of connection of the storage battery
    1 — the Positive plug
    2 — the Positive wire
    3 — the Negative wire
    4 — the Negative plug

In order to avoid alarm system operation the wire should be disconnected no later than in 15 seconds after ignition switching off.

  1. At the corresponding execution lift a protective cover and disconnect a positive wire.

  1. Turn out a fixing bolt, remove an assembly bracket and take the battery from an impellent compartment.

  1. In case of need turn out fixing bolts and remove a basic arm (the adjusting pallet) batteries, - do not forget to liberate from all intermediate clamps electroconducting.

Installation

Installation is made as it should be, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. After connection of wires grease terminal knots with technical vaseline.

The negative wire is always disconnected first of all and connected in the last!

Storage and commissioning

If refusal of using the car for the term of more than two months is planned, the storage battery should be removed and cleaned on storage. The optimum temperature of storage of the battery makes from 0 to +27°С. At these temperatures the self-category of the battery is minimum. In order to avoid irreversible destruction of the lamely it is necessary to make a charging of the battery cleaned on storage not more rare than once a month.

Besides a discharge not used battery is subject to a sulfatatsiya. If to make a charging of such battery the device for a fast charge, she will not perceive a charging current, or as a result of a sulfatatsiya is recharged and to further use is not subject.

Before refusing use by the failed battery, make the following checks:

  • Measure electrolit density (see. Head Routine maintenance), - if the difference between density in separate banks does not exceed 0.04 g/ml, it is necessary to charge the battery the normal charger.
  • After a charge check the battery under loading, - if characteristics of the battery are lower nominal (see. Specifications), the battery is subject to replacement.
  • If the electrolit density in one or in two next banks considerably differs (for example, in five sections it makes 1.16 g/ml, and in the sixth - 1.08 g/ml), in the battery take place short circuit and its further use is inexpedient.
