How much the accumulator reserve suffices?

How long the electric power consumer can work from the accumulator, we calculate under the formula: duration of operation = accumulator capacities х on pressure of an onboard network and деленная 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:

The accumulator
Parking fires
Lay fires
The alarm system
36 And hour
Nearby 28 hour
Nearby 6 hour
Nearby 3 hour
44 And hour
Nearby 35 hour
Nearby 8 hour
Nearby 4 hour
70 And hour
Nearby 56 hour
Nearby 12 hour
Nearby 7 hour

Influence of temperature on the accumulator

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