As far as the accumulator reserve suffices?

How long the consumer of the electric power can work from the accumulator, we calculate on a formula: duration of operation = capacities of the accumulator x on tension of an onboard network and delenny on capacity of the consumer of the electric power. But in practice you never should count on full capacity of the accumulator, but only on a charge to 2/3 its nominal capacities. In this case it is necessary to count, for example, on the following duration of operation:

Accumulator
Parking fires
Lay fires
Alarm system
36 And hour
near 28th hour
near 6th hour
near 3rd hour
44 And hour
near 35th hour
near 8th hour
near 4th hour
70 And hour
near 56th hour
near 12th hour
near 7th hour

Influence of temperature on the accumulator

The accumulator has a property to react to cold of subjects worse, than below its charge. In completely discharged condition it is so sensitive that at a frost can freeze and burst. But at a full charging the accumulator transfers cold rather well. Before approach of a cold season it is recommended to check a charge condition in the old accumulator.
