| THE GENERAL DATA |
The accumulator is a device for energy storage in the chemical form which can be used as an electricity.
The accumulator works thanks to that two various metals, being in an acid solution, develop an electricity.
The basic indicators of accumulators
Some important facts about accumulators which will help you are more low mentioned and to your buyers correctly to choose the accumulator for the car.
Аккмулятор 100 % possess efficiency at 27 ° S.Pri–18 ° about efficiency of the same аккмулятора 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. Specify in necessity big аккмуляторов, especially in cold climates.
Starting capacity (starting amperes) shows ability of the accumulator to start the car in the conditions of very cold weather. It shows quantity of amperes which develops the accumulator within 30 seconds at–18 ° With without a power failure more low 7,2 volt (a minimum level demanded for reliable start). The above this indicator, the more starting capacity of the accumulator.
Reserve capacity shows extent of time in minutes during which the accumulator provides 25 amperes at 27 ° with S.Etot the 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 more low the accumulator it will be bad to be charged in connection with increase of internal resistance. At short trips in the winter the energy spent by the accumulator on start-up, is not compensated. As a result the accumulator works on deterioration, 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 высококомпрессионные engines with the big working volume and cars with conditioners. It once again underlines importance of a correct choice of the accumulator according to the car engine.
