Repair and car operation

The accumulator is a device for energy storage in a chemical form which can be used as an electricity.

The accumulator works thanks to that two various metals, being in acid solution, develop an electricity.

Main indicators of accumulators

Below some important facts about accumulators which will help you are given and it is correct to your buyers to choose the accumulator for the car.

Akkmulyator possesses 100 % efficiency at 27 ° S.Pri–18 ° About efficiency of the same akkmulyator falls to 40 %. Now to start the engine, it is necessary to have more than twice more energy, than it was necessary рпи 27 ° for S.Podcherknite this important factor to your clients. Point to need of big akkmulyator, especially in cold climates.

The starting capacity (starting amperes) shows ability of the accumulator to start the car in the conditions of very cold weather. It shows number of amperes which develops the accumulator within 30 seconds at–18 ° With without power failure below 7,2 volts (the minimum level demanded for reliable start). The this indicator, the more starting capacity of the accumulator is higher.

The reserve capacity shows extent of time in minutes during which the accumulator provides 25 amperes at 27 ° with Page. This factor represents 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 of a charge.

Functioning in the conditions of cold weather

In winter conditions at–18 ° With and below the accumulator will be badly charged in connection with increase of internal resistance. At short trips in the winter the energy spent by the accumulator for start-up, is not compensated. As a result the accumulator works very hard, is constantly discharged and eventually refuses.

"Hot start"

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, or it is more. It especially extends on vysokokompressionny engines with large working volume and cars with conditioners. It once again emphasizes importance of a right choice of the accumulator according to the car engine.
