7.1.2. Storage battery

The car considered in this management have the electric system working energized of 12 V.Massa of a body incorporates to the minus plug of the storage battery. The storage battery is in a motor compartment or under a back seat (models with the conditioner, and also some diesel updatings).
The storage battery carries out three main functions in electric system of the car:
– gives an electric current for engine start-up;
– stabilizes tension in electric system;
– can provide in a short space of time with a current when consumption of energy exceeds target capacity of the generator.
Tight storage batteries standard for all cars. They on the case have no jellied jams. The storage battery is completely tight, not including two small lateral openings for ventilation. These ventilating openings allow to disappear to the formed gases.
Tight storage batteries have the following advantages over ordinary storage batteries:
– for durability of storage batteries it is not necessary to add waters;
– the battery is protected from a recharge. If too big tension is brought to the storage battery, it will not accept so much current, how many the ordinary battery. Increase of tension will continue to charge the ordinary battery that leads to a gazoobrazovaniye and electrolit loss;
– the battery is subject to a self-charging as the ordinary battery. It is very important, when the car costs in one place long time;
– at the smaller sizes and weight tension and a current remained former.
The storage battery has two indicators:
– the indicator of capacity of the storage battery is defined at 27 °C which at a full charging provides 10,5 In and more;
– the indicator of the storage battery at start-up of the cold engine is defined by testing at–18 °C which shows battery capacity at a provorachivaniye of a cranked shaft at the cold engine.
The reserve capacity of the storage battery is defined as the greatest possible long time for movement in the night from the minimum electric loading without use of target capacity of the generator. Expressed in minutes, reserve capacity (or indicator Е) is necessary time for the full charged battery room of the battery at 27 °C and a discharge a current 25 And for achievement on tension plugs in 10,5 Century.
Testing сипы a current at start-up of the cold engine is carried out at–18 °C. The minimum indicator of a current which should be kept by the battery at the set temperature while there is the minimum tension in 7,2 Century.
This indicator is measured at start-up of the cold engine.
Service life of the storage battery is not boundless. Nevertheless, at appropriate leaving the storage battery will serve many years.
If the storage battery passed test well, but failures in work for no apparent reason are established, the following factors can be a cause of defect or refusal:
– any device was left included on all night long;
– the car moved to the short periods on small speed;
– electric loading of the car exceeded target capacity of the generator, is frequent with inclusion of the non-standard equipment;
– malfunction in charging system: sliding of a belt of the generator, malfunction of the generator or malfunction of a regulator of tension and t. д;
– battery misuse: not carrying out cleaning, fixing of plugs or weakening of clips;
– mechanical malfunctions of electric system: the short-circuited or jammed wires.
Tight storage batteries have the built-in areometer with temperature compensation in its top part, used for below-mentioned diagnostics:
– when look at the areometer, make sure that the top part of the battery the pure;
– at normal work two indications should be received:
The visible green point emergence of green color called «a green point» means that the battery is ready to testing;
Dark green invisible point – if there are complaints to start-up of the cold engine, battery testing is necessary. During the same time electric systems and a charging should be checked. There can sometimes be the third condition:
Pure or light yellow color – level of liquid is lower than an areometer tip. It can become the reason of an excessive or long charging, excessive or normal wear of the battery. Therefore the charging and electric systems can need check if there are complaints to start-up of the cold engine. If the battery – the reason of the complaint to bad start-up of the cold engine, replace it.

Check of degree of a zaryazhennost of the battery
Electrolit density together with tension measurement on conclusions of the storage battery allow to draw an exact conclusion on degree of a zaryazhennost of the battery. For check the areometer which can be got in specialized shop serves. The enough of electrolit, the rises more the areometer float (emerges). On a scale of the areometer of value are expressed in terms of density (g/cm3).
During measurement of density of electrolit watch that on a battery surface, the body and other details from a pipette of the areometer did not fall the drops of electrolit containing sulfuric acid which causes corrosion and leakages of a current.
At measurement of density of electrolit the temperature of electrolit should be in limits of 20-30 °C. The density of electrolit should be measured in each element (bank) of the storage battery. After measurement of density of electrolit it is possible establish degree of a razryazhennost of the battery.
In all elements of electrolits should have identical density.
The electrolit density in completely charged storage battery makes 1,28 g/cm3.
The electrolit density to the storage battery discharged for 25 %, makes 1,24 g/cm3.
The electrolit density to the storage battery discharged for 50 %, makes 1,20 g/cm3.
The storage battery discharged more than for 25 % in the winter and more than for 50 % in the summer, remove from the car and recharge.

The storage battery discharged more than for 25 % in the winter and more than for 50 % in the summer, remove from the car and recharge.

Charging of the storage battery
The storage battery with a green point shows that the charging is not necessary, while the battery will not be discharged as, for example, at start-up of the cold engine.
At a charging of the storage battery with the pressurized plugs out of the car, establish an adapter. Make sure that all connections of the charger pure and reliable. For the best result the battery should be charged, when electrolit and plates have room temperature. Extremely cold batteries can not be charged some hours after the charging beginning.
Charge the storage battery, there will be no yet a green point. In the course of a charging the battery should be checked each 30 minutes. The inclination or agitation can be necessary for emergence of a green point.
After a charging the storage battery should be tested.
Time necessary for a charging of the storage battery, depends from:
– the size of the battery – for completely discharged high-capacity battery intended for work in a heavy mode, time in 2 times more than for a charging of the storage battery of the car is necessary;
– temperatures – the battery charging at–18 °C will need more time, than at 27 °C. When the charger is connected to the cold battery, at first degree of a charging will be very low, but in process of growth of temperature of the battery degree of a charging will raise;
– abilities of the charger – the charger with a current of a charging 5 and will demand more time for a charging, than the charger with a current of a charging 30 And or is more;
– charge conditions – for a charging of completely discharged battery more charge is necessary twice, than for a charging of two half discharged batteries because in completely discharged battery of electrolits comes nearer on structure almost to pure water and is the bad conductor. Then, as the charging current leads to increase in the content of acid in electrolit, also charging degree respectively increases.
Before a charging disconnect from the battery a plusovy cable and a weight cable, at first a weight cable.
Before a charging check electrolit level, if necessary add the distilled water.
The frozen battery (the battery, electrolit in which froze) before a charging defreeze. Completely charged battery freezes at temperature of-65 °C, half charged battery – at temperature of-30 °C, the discharged battery – at temperature of-12 °C.
Charge the battery only in well aired room. At a charging of the established battery leave a car cowl open.
At a normal charging value of a charging current makes about 10 % from battery capacity. (that is the battery in capacity 50 And · should be charged by a current in size about 5,0 And) h. As time of a charging it is possible to accept value of 10 h.
Connect a plusovy conclusion of the storage battery to a plusovy wire, a minus conclusion of the battery with a minus wire of the charger.
During a charging the temperature of electrolit should not exceed +55 °C, if necessary, interrupt a charging or reduce value of a current of a charging.
Charge the battery until in all elements of the battery plentiful liberation of gas and will not begin, at the following consistently one after another in an hour the 3rd measurements, the density of electrolit and tension will not cease to increase.
After a charging check electrolit level, if necessary add the distilled water.
Charging of completely discharged battery room of the battery
Below-mentioned procedure use for a recharge of completely discharged battery:
– measure tension on battery plugs by the exact voltmeter. If value of the measured size is lower 10 In, the current of a charging will be very low, and it can take some time before the battery will accept a superfluous some milliamper;
– put the charger on a high place. Some chargers have the scheme of protection against the return polarity preventing a charging at the wrong connection with plugs of the battery. Completely discharged battery has no sufficient tension to put in action this scheme even if wires are connected correctly. It will lead to that the battery will not be charged. Therefore follow special instructions of the producer of chargers that the charger turned on and started to charge the battery with a low voltage;
– in chargers tension and current regulators are provided. Time necessary for a charging of the battery depending on various values of tension, are provided below.

Time of a charging of the storage battery depending on initial tension of the battery
If it is impossible to measure the charge received by the battery after the expiration of time of a charging, it is necessary to replace the battery.
If the received charge is measured in charging process, the battery is serviceable, the charging should be finished as usual.
If the charge received by the battery is not measured after the expiration of time of the charging, the calculated above-stated method, it is necessary to replace the battery.
If the received charge is measured during charging time, the battery is serviceable and the charging should be finished in the usual way.


Care of the storage battery
From time to time it is necessary to perform the following works that the battery served more long and its capacity was supported maximum.
Always it is necessary to keep the battery and details surrounding it clean. The surface of the battery should be always dry as differently, between separate banks there can be superficial currents of leak because of what the battery will be discharged in itself.
Level of electrolit should be constantly at a ring located from the bottom party of the jellied chamber. For долива it is necessary to use the distilled water.
In cold weather to leave the battery in the charged condition as it (is more exact, the electrolit in it) will freeze. Poorly charged batteries freeze already at temperature about-10 °C.

Storage of the storage battery
The batteries, not being used a long time, are discharged in itself and sulfatatsiya of plates can be subject. If such batteries to charge the fast-charger, they do not accept a charging current and because of, a so-called, superficial charging.
Before rejecting the battery, follows check it:
Check electrolit density. If the density in all elements differs no more than on 0.02 g/cm3, the battery should be charged the charger.
Check the battery after a charging under loading. If values do not correspond demanded, the battery is faulty.
Check electrolit density. If the electrolit density in one or several banks is much lower, than in the others (for example, in five banks density makes 1,16 g/cm3, and in one 1,08 g/cm3), the battery has internal short circuit.
To avoid battery presenilation, it is necessary to charge the battery being stored, each 3 months.

Self-category of the storage battery
Depending on car updating to process of the normal self-category of the battery consumption of energy of constantly acting consumers of energy is added. Therefore the battery on not being maintained car should be charged time in one and a half month. If there is a suspicion on existence of superficial currents of leak, follows check an onboard network of the car.
For check use completely charged battery.
Establish on the ampermeter (with a limit of measurement 0–5 мА and 0–5 And) the highest limit of measurement. Turn on the ampermeter between a minus conclusion of the battery and a weight cable. The Plusovy wire of the ampermeter connect to a plusovy conclusion of the battery, a minus wire of the ampermeter – to a minus conclusion of the battery.
Switch off everything consumers of the electric power, close all doors and a luggage carrier, switch off a plafond of illumination of a motor compartment.
Switch a limit of measurement of the ampermeter towards reduction until there will be any indications (admissible value makes 1–3 мА). Taking out one after another safety locks from the block of safety locks, disconnect consistently all electric chains. If at disconnection of one of chains of the indication will fall to 0, in this chain it is necessary to look for a malfunction source. Possible malfunctions: the korrodirovavshy or polluted contacts of the electric sockets, the ground wires, internal short circuit in electric equipment elements.
If in the chains of malfunction protected by safety locks it is not revealed, it is necessary to disconnect wires from unprotected by safety locks of devices: generator, starter, elements of system of ignition.
If at shutdown of one of unprotected chains of the indication of the ampermeter will fall to 0, repair or replace the corresponding element. At leakage of a current in a starter or ignition system always check (according to the scheme) the ignition and starter switch.

Removal and installation of the storage battery
At shutdown of the storage battery from memory of the central block of a control system of the engine and a transmission, anti-blocking system of brakes, and also from memory of some other electrodevices, for example, a radio receiver and hours data on taking place malfunctions are erased. After connection anew program the corresponding devices. Some serially established radio receivers have a protective code. The protective code prevents unauthorized use of a radio receiver if its food was disconnected. A food of a radio receiver and hours is disconnected, if the storage battery, for example, is disconnected, the receiver acts in film or fuses the corresponding safety lock.
Unscrew nuts and disconnect the "negative" plug and then the "positive" plug from the storage battery.
Unscrew a nut of fastening of an arm of support of the storage battery.
Remove an arm of support of the storage battery.
Remove the storage battery.
Before installation clear polar conclusions of the storage battery, the brass wire brush for this purpose will approach. For prevention of corrosion cover battery conclusions with special greasing.
Installation of the storage battery carry out to sequences, return to removal.
Tighten a nut of fastening of an arm of support of the storage battery the moment of 6-8 N · m.
Tighten nuts of fastening of plugs of the storage battery the moment of 9-12 N · m.
