Check and loading of the battery

Watch also office check of a condition of the battery, its departure and loading of the head Routine maintenance.

maloobsluschiwajemaja battery

If the annual movement of the car is not enough, it is necessary to measure it is necessary for check of sarjaschennosti of the accumulator of each 3 months elektrolita density. Measure areometrom density.

Think that data are provided for elektrolita temperature 15 °C. At temperature increase have to go on each 10 °C after 0.007, at similar reduction add - to hold after 0.007.

If the condition of the battery causes fears, check elektrolita density in each can. Distinction is more than on 0.040 designates on loss of elektrolita or damage of disks.

If distinction passes into density 0.040, the battery is subject to compensation. If distinction is satisfactory in density, but is unloaded the battery, it is necessary to invite them and to check elektrolita density. The sequence of actions of a nizheperechislen at shop.

Not served battery

If on the car the dense battery is defined to check density of elektrolita and, it is impossible to restore level it. It is possible to check a condition of the battery by means of the installed indicator or the external voltmeter.

Several models are equipped with not served batteries in which body sarjaschennosti step indicator is installed. It is located above and changes color at change of a step of sarjaschennosti of the battery. If the indicator has green color, the battery is invited completely if to invite it the indicator of red color - the battery is necessary. The sequence of actions of a nizheperechislen at shop of the battery in this chapter. Batteries of other producers can also have the installed sarjaschennosti step indicator. In this case you follow instructions which are provided in maintenance instructions of the battery.

Batteries of all types

When checking the battery by means of the external voltmeter you include it to clips and you compare the received result to data which are provided in specifications. Result of measurements correctly if the battery was not invited at least during the last 6 h. If it was invited - will accept on 30 seconds of a searchlight, then you expect 5 minutes and you check effort on clips. At the same time all other electric equipment (even wnutrissalonnoje lighting reception) has to be made.

If result of measurements less than 12.0 In, so the battery is unloaded, and effort 12.0 to 12.4 about partial rasrjaschennosti it is signaled.

If it is necessary to invite the battery, take them from the car (with watch office check and regulation of a corner of Zuvorkommens of ignition) and a priglasta, procedures the following which is described below.

Check of strengthening of clips of the battery and fastening

If the battery is strengthened badly or clips are not strengthened, then the research can be early failure of the battery because of vibration, ignition of cables or defect in operation of the electric equipment.

As at not the connected battery the memories given electronic blocks, for example, of the radio receiver wash, undertake with remarks after removal and the device of the battery (known watch chapters for Routine maintenance and for the operation manual)

Translate battery clips to too various parties and check reliability of its strengthening, tighten if it is necessary.

If the battery is strengthened badly, tighten a bolt of strengthening of the moment of 20 Nanometers.

Check of the battery under loading

EXECUTION ORDER

1. Connect the voltmeter in battery clips.
2. Start the motor and check effort.
3. During start of the motor at completely invited battery the effort should not fall lower than 10 V (at elektrolita temperature along with these +20 °C).
4. If the effort also elektrolita density in various sections falls is strongly various, the battery also it in the damaged state needs to be replaced.

The following sequence of actions can differ from recommended thanks to producer of the accumulator which is defined by car. In this case you use recommendations of the producer.

Usually and maloobsluschiwajemaja battery

It is necessary to invite the battery it from current which equals 10% of capacities (for example if the power of the battery forms 45 Atsch it is necessary to invite them it from current 4.5) until during 4 h density of elektrolita does not increase in banks.

On the other hand, the automatic charger with current about 1.5 is made on all night long or handed, probably.

Chargers of the "accelerated" type which can invite allegedly the accumulator for a couple of hours completely use it not recommended as they at big streams of a disk of the battery and collapse can overheat.

At shop of the battery you follow that temperature of elektrolita did not pass 37.8 °C.

Loading of not served battery

For full load of the battery of the given type it is bolscheje time as or it is usually necessary for loading of maloobsluschiwajemoj. The term of shop depends on a step of rasrjaschennosti and can receive up to 3 days.

The effort which is made by the charger has to lie in volume of 13.9 - 14.9 volt, current should not pass 25 A. Under existing conditions the battery can be used by 3 h, the effort on clips has to be about 12.5 volts. Achievement of full shop will receive bigger long time.

Remarks after precautionary measures

Before shop of the battery you declare to yourself with remarks after precautionary measures which are given in office check of a condition of the battery , its leaving and loadingof ).

Do not switch off the battery at the working motor.

You never close the nakorotko battery, i.e. You do not connect positively (+) and is negative (-) poljussy. At the same time the battery is warmed up and can burst.

Do not use naked flame near the battery. elektrolit is poisonous. Do not allow a meeting on the person, on skin and on clothes. Otherwise you erase elektrolit to water enough.

At the battery with gasootwodom is central, at freight, traffic jams (crosswisely schliz) you do not pull out.

Before shop of the freezing battery you give it ottajat. The invited battery freezes at a temperature along with these 65 °C, the semi-invited battery at a temperature along with these 30 °C and unload at a temperature along with these 12 °C. After a rope you check the battery for existence of cracks. If it is necessary you replace.

At freight of the battery of the normal charger or establishment with the accelerated shop you accept the battery. As at least, it is negative (-) and a positive cable (+) you exclude.

At application of the portable charger (small current) loading can be filled without removal of the battery. At the same time a cable of accession to onboard network, do not demand to exclude. It needs naturally to be considered, data of the producer of the battery.

Loading is unloaded strongly also by battery sulfatirowannoj

It is impossible to invite strongly unloaded battery of establishment for bystry freight at all.

The battery, long time sulfatirujetsja is not used over time (will unload, at a long stop of the car), and, for example.

If the effort of idling of the battery lies lower than 11.6 In, then the battery strongly unloads is accepted. Check effort of tranquility, it and loading) address office to check of a condition of the battery, leaving at the same time.

At strongly unloaded elektrolit battery exists almost from water.

At a negative temperature such battery can, and freeze a body of the battery to burst.

Strongly unloaded sulfatirujetsja battery, i.e. on a surface of electrodes big weak and soluble crystals are formed sulfur-containing swinza. elektrolit at the same time loses transparency and gets weak white coloring.

If strongly unloaded battery directly is invited after category, again there is sulfatazija. Otherwise disks of the battery continue and to do firm the possibility of freight of the battery for long time remains limited.

Strongly unload and sulfitirowannaja the battery of the lowered current has to be invited along with 5%, i.e. at it is, for example, force of sarjadnogo of current 3 A has to form capacities of the battery of 60 Atsch

Chest tension should not form 14.4 W any more.

Bystry loading / help at start

From establishment for bystry freight you invite the battery only for supply of start of the car. At the same time force of sarjadnogo of current forms 20% and more than the power of the battery. At the same time the battery is damaged as big streams it is irritated. It is for a long time necessary time not to invite the used and strongly unloaded battery of establishment for bystry freight is not as it leads to sulfatazii.
