The storage battery - the general information, recommendations about service

Established on the car 12-voltnaja the battery consists of six банок in which positive and negative plates (ламели), shipped in a solution of sulfuric acid are placed. The battery main task is production of the current necessary for realisation of start of the engine, ignition of a working mix, illumination, and also for maintenance with a food of other onboard or auxiliary consumers of the electric power.

Absolute return of the battery takes place at an ambient temperature 27 hailstones. At-18 hailstones. Efficiency of return falls to 40 % and for realisation of start of the engine it is required in two with small time of more energy.

Starting capacity (starting current) characterises ability of the accumulator to start the engine in the conditions of very cold weather. It shows a current in amperes which gives the accumulator within 30 seconds at temperature-18 hailstones. Without a power failure more low 7.2 In (a minimum level demanded for reliable start). The above this indicator, the more starting capacity of the accumulator.

Reserve capacity shows time in minutes during which the accumulator gives a current 25 And at 27 hailstones., i.e. time during which the accumulator ensures functioning of all auxiliary devices in the car at night and in the conditions of bad weather at the faulty generator.

In winter conditions, at temperatures more low-18 hailstones. Efficiency of additional charge of the battery decreases in view of increase of internal resistance. At short trips in the winter the energy spent by the battery on start of the engine, has not time to be restored and the battery begins works on deterioration, being gradually discharged and, eventually, fails is irreversible.

In summer months at long trips the engine strongly heats up, and often happens that it is difficult for starting anew. For such "hot" starts sometimes it is spent not less energy of the battery, than in frosty weather. Told in a special measure concerns to высококомпрессионным to engines with the big working volume of cylinders, and also the models equipped with system K/V.

Acquisition of the new storage battery

Told above specifies in importance of correctness of a choice of the storage battery with the account of parametres of the engine and a vehicle complete set.

At purchase of the new storage battery it is necessary to pay attention to its performance data:

  • Nominal target pressure. Has identical value (12) for all batteries applied on cars that practically excludes probability of an error.
  • The capacity measured in Amperes/hours (А/h) and, roughly speaking, defining a stock of the electric power containing in the battery. On a choice of size of the given parametre depends, as long the battery is capable to provide possibility проворачивания the engine with a starter, is more exact - how many it is possible to make attempts of start of the engine. The price of the storage battery is almost directly proportional to its capacity.
  • Starting current (), i.e. a current submitted on a starter at start of the engine. The size of a starting current on batteries can be specified under four different standards: GOST (for domestic accumulators), EN (the standard of Uniform Europe), SAE (the American standard) and DIN (Germany). Last, German standard, is closest to ours STATE THAT and on the majority of batteries of the European manufacture is put down "by default" i.e. when the standard system is not specified. The the starting current above, the the big turns develops a starter and to those больший it is capable to transfer a twisting moment to an engine flywheel.

In an ideal, the got replaceable battery on the performance data should correspond completely to requirements of Specifications of the Head of System of an electric equipment of the engine at which observance battery service life will be maximum. Hardly it is possible to consider acquisition of the battery of smaller capacity as good economy of money as it will serve much less and, besides, can lead to the unpleasant efforts connected with start of the engine in a winter season. It is not necessary to get the battery with excessively big starting current, - such hobby is interfaced to risk of failure of a starter. If the standard battery does not provide due проворачивание the engine, will be more correct to begin with to make replacement of impellent oil, - that most likely will lead to automatic elimination of a problem.

Lately the country market is overflowed by the poor-quality goods and fakes. The storage battery also are not an exception. There are some signs on which it is possible with sufficient degree of probability to distinguish the original from a fake. The first and, perhaps, the main thing: on the battery case the country-manufacturer and factory-manufacturer should be necessarily specified, it is better, if with the address. The second: manufacturing date should be specified that special value has for batteries of tight (unattended) type. The delivery complete set necessarily should include characteristics sheet while instruction presence is not strictly obligatory. The third: qualitative batteries differ good appearance. The case should have equal edges, to be equipped by reliable stoppers and the smooth, covered protective caps polar plugs which quite often become covered by a layer of special anticorrosive greasing.

Battery gymnastics

The gymnastics of the failed battery should be made according to instructions of manufacturers charger devices.
