On how many there are enough reserves?

As the consumer of food can long function at the expense of current from the accumulator, it is possible to calculate by the following formula:

Operation time = the capacity of the rechargeable battery increased by tension of onboard network and divided into the consumer's power. In practice you, however, never should count on the full capacity of the accumulator but only from 1/2 to 2/3 nominal capacities. At the same time the following terms of operation turn out, for example:

Rechargeable battery
Parking light, near
Parking light, near
Alarm light system, near
40 Ач
35 hours
12 hours
3 hours
63 Ач
56 hours
19 hours
5 hours

Influence of temperature of air on the accumulator

Accumulators have property to react to cooling especially negatively, than less they are charged. Absolutely discharged accumulators are so sensitive that in a frost can even freeze and burst. If the rechargeable battery, on the contrary, is charged to the full, it transfers cold rather well. Before approach of cold season it is recommended therefore on old accumulators to carry out control of degree of the category.
