18.104.22.168. Charging of the storage battery
The storage battery with a green point shows that the charging is not necessary, while the battery will not be discharged as, for example, at start-up of the cold engine.
At a charging of the storage battery with the pressurized plugs out of the car, establish an adapter. Make sure that all connections of the charger pure and reliable. For the best result the battery should be charged, when electrolit and plates have room temperature. Extremely cold batteries can not be charged some hours after the charging beginning.
Charge the storage battery, there will be no yet a green point. In the course of a charging the battery should be checked each 30 minutes. The inclination or agitation can be necessary for emergence of a green point.
After a charging the storage battery should be tested.
Time necessary for a charging of the storage battery, depends on the following factors:
– the size of the battery – for completely discharged high-capacity battery intended for work in a heavy mode, time in 2 times more than for a charging of the storage battery of the car is necessary;
– temperatures – the battery charging at–18 °C will need more time, than at 27 °C. if the charger is connected to the cold battery, at first degree of a charging will be very low, but in process of growth of temperature of the battery degree of a charging will raise;
– abilities of the charger – the charger with a current of a charging 5 And will demand more time for a charging, than the charger with a current of a charging 30 And or is more;
– charge conditions – for a charging of completely discharged battery more charge is necessary twice, than for a charging of two half discharged batteries because in completely discharged battery of electrolits comes nearer on structure almost to pure water and is the bad conductor. Then, as the charging current leads to increase in the content of acid in electrolit, also charging degree respectively increases.
Before a charging disconnect from the battery a plusovy cable, then a weight cable.
Before a charging check electrolit level, if necessary add the distilled water.
The frozen battery (the battery, electrolit in which froze) before a charging defreeze. Completely charged battery freezes at temperature of-65 °C, half charged battery – at temperature of-30 °C, the discharged battery – at temperature of-12 °C.
Charge the battery only in well aired room. At a charging of the established battery leave a car cowl open.
At a normal charging value of a charging current makes about 10 % from battery capacity. (that is the battery in capacity 50 And should be charged by a current in size about 5,0 And). Time of a charging about 10 h.
Connect a plusovy conclusion of the storage battery to a plusovy wire, a minus conclusion of the battery – with a minus wire of the charger.
During a charging the temperature of electrolit should not exceed +55 °C, if necessary interrupt a charging or reduce value of a current of a charging.
