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:

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.
