1.17.4. The accumulator
THE GENERAL DATA

Has struck a frost, and the accumulator still yesterday vigorously twisting a starter, refuses to do it flatly. Anything surprising – when you charged its last time?

If the accumulator youngish (till 3–4 years) on the threshold of winter it needs to be washed up outside to clear plugs and completely to charge – if the car it was constantly maintained in a city, the battery charge is for certain far from the nominal. If the accumulator old and to nominal capacity is not charged, change without meditations, differently in the winter it for certain will bring you – capacity and so strongly falls with temperature fall, and here also the raised power consumption – a heater, heating of seats, light, yard keepers, a heater of back glass...

By the way, on responses of experts, average duration of "a high-grade life" accumulator makes about twelve months, gradual withering further begins. And the peak of sales стартерных batteries, according to sellers, is necessary just for the autumn.

Times when the automobile owner was knocked down in search of the new accumulator, have passed for a long time – from a variety of trade marks and models on regiments of shops рябит in eyes. What to choose – the private affair of everyone. We will notice only that in the market now it is possible to allocate two price groups – batteries in cost over $60 (usually to $100), for example, "Bosch", "Steco", "American", "Fiamm", and accumulators under the price below $60 ("Mutlu", "Inci", "Centra", "SAEM" etc.).

Higher prices of batteries of the first group are defined by more perfect technology of their manufacture. These accumulators, as a rule, concern a category of the unattended. Special types of electrolits and tight execution of such batteries increase a resource of their operation and provide high стартерные the currents guaranteeing проворачиваемость of the engine even at strong frosts. Leading manufacturers without fail use now technology of packing of plates therefore it is possible to avoid short circuit of the battery in case of their destruction.

Cheaper accumulators demand periodic service – checks of density of electrolit and measurement of its level. We will remind that the density of electrolit for the winter period should be not more low 1,29.

Often at purchase of the new battery try to choose in its capacity more if only has got on the place taken away for it. But capacity – not the main thing. Where it is more important стартерный a current which is provided with the battery. After all even at the accumulator with the big capacity this indicator (because of the big own resistance) can appear more low, than at the accumulator with smaller capacity. Besides, for the battery with большей in capacity higher current of the additional charge is required, which generator of your car will not provide, and the battery while in service will be discharged more and more that is pitiable will affect term of its service.

By the way, if buy the battery different from regular, pay attention to an arrangement of its conclusions – accumulators come across to "return polarity" which plugs of a wire of your car can and not reach.
