The battery - the main instructions, shutdown and acquisition of the new battery
Defines 12 V the battery exists from 6 cans which contain positive and negative disks which are lowered in the solution of sulfur-containing acid. Development of current belongs to a battery task for start of the car, ignition and for lighting, and also for other consumers of the electric power. The battery decides 100% efficiency at 27 °C. Bei-18 °S falls efficiency to 40%. Now, to start the motor, it is necessary to have more than twice bigger amount of energy, than it was necessary at 27 °C. The starting power (starting current) shows ability of the accumulator to start the car under conditions of very cold weather. It shows current in ampere which returns the accumulator within 30 seconds at 18 °S without effort ambushes below than 7.2 volts (the minimum level which is demanded for sure start). The this indicator, the bigger number of the starting power of the accumulator is higher. The reserve power shows time in minutes during which return the accumulator current 25 A at 27 °C., i.e. time during which the accumulator guarantees operation of all auxiliary devices by car at night and under conditions of bad weather at the wrong generator. In winter conditions at 18 °S and the battery badly will be invited in connection with increase of internal resistance below. At short trips energy which is spent by the battery for start is not restored in the winter. Then the battery works for sale, will constantly unload and, at last, fails. Within summer months the motor is strongly heated after long trips, and often happens that it is difficult to start again. They sometimes demand "hot starts" as much the power, it and at cold weather how many, or it is more. Especially it stretches for wyssokokompressionnyje motors with large working volume and cars by means of the conditioner. It once again emphasizes importance of a right choice of the accumulator according to the car motor. Acquisition of the new battery It is the probable, most important then the buyer has to pay attention, characteristics of the accumulator. You 3.To itself the first - nominal force to be mistaken it is identical at all batteries, and it is impossible. When purchasing it would be desirable to check the nagrusotschnoj battery from a fork. The second means - the power which is measured in And / h. (And / h), roughly speaking, quantity of the electric power which remains in the accumulator. Depends on power as from a starter it is long possible to turn the motor, more precisely - how many attempts of start of the motor it is possible to do. The price of the accumulator is really absolutely proportional to its power. And the third characteristic - starting current (it is measured in ampere:), i.e. current which is served on a starter during start. On its accumulators can designate on 4 various systems: gost (on local), EN (the standard unified Europe), THIS (the American standard) and the German industrial standard. The last, German standard, is most of all close in our STAATSJENE and on the majority European will be "as preliminary installation", i.e. is put if the system of the standard is not specified. It sometime it is more, the quicker and with bolschej at most prowernet starters the motor. It is better if you buy the battery with those characteristics you which are specified in the maintenance instruction of your car: thus it will serve you longer at the minimum costs. Can and buy the battery of smaller power save, but it will serve you small usual term and it is bad to cope with winter start. Being bought by the battery even power nenamnogo bolschej, you will not win in time as constantly nedosarjad of the accumulator will lead to sulfatazii of disks, and will lose in money. It is not necessary to be fond of also raised starting current it: will burn a starter. Better you replace oil in the motor, and problems with start will not be. Last time the market of the country of defective goods and Fälschungen is crowded. Accumulators are not an exception. Give several signs after which it is possible to distinguish the original from forgery with a sufficient accuracy. The first and, perhaps, main business: on the accumulator the land producer and the giving-out enterprise have to be by all means specified, it is better if with the address. The second - has to be specified date of production that if the accumulator is very important it is filled in. The passport of the car has to be attached to each batareje, and existence of the instruction is not guaranteed. It is connected with what in the West accumulators by the piece almost do not sell, they establish experts in stations of service. The third party is a high-quality accumulator without qualitative body, a good stopper and wywodnych of clips unimaginably which are covered quite often greased with technical protective lubricant of oxidation and above color Plast-kolpatschkami is smooth. |
