On reserves how many are enough?
As the consumer of food at the expense of current from the accumulator can long function, it is possible to calculate on the following formula:
Operation time = the battery capacity increased by tension of an 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. Thus the following terms of operation turn out, for example:
|
Battery

Parking light, near
|
Parking light, near

Alarm light system, near

40 Ach
|
35 hours

12 hours
|
3 hours

|
63 Ach
|
56 hours
|
19 hours
|
5 hours

Influence of temperature of air on the accumulator
Accumulators possess 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 battery, on the contrary, is charged to the full, it transfers cold rather well. Before approach of a cold season it is recommended therefore on old accumulators to carry out control of degree of the category.
