Battery charging

Connection of the home charger


    Connect plusovy a charger wire to accumulator plus, a minus wire to an accumulator minus. At a charging the accumulator can remain established in the car. If weak, a wire of the accumulator it is possible not to disconnect the home charger. Storage jams can remain screwed up. The gas which is forming at a battery charging, can be removed through ventilating openings in jams. The charging current should make in the beginning about 10 % of capacity of the accumulator (for example, 7 And at the accumulator in 70 And hour) and automatically to decrease in the course of a battery charging. The accumulator is considered completely charged if within two hours the acid density in it does not increase. During a battery charging the distilled water partially decays. Gas vials are formed of hydrogen and oxygen – the detonating gas possessing high explosive ability. Therefore it is necessary to take care of good ventilation of a room especially in case the accumulator is charged by a powerful current. At a battery charging it is impossible to smoke near it and to use open fire. Detonating gas can ignite also from an iskreniye arising at connection and shutdown of charging the device or wires.
