The low-served storage battery

The car is equipped with so-called low-served storage batteries. These batteries at carrying out service demand only electrolit addition.

Thus it is necessary to observe the following rules:

      •  The cover of the battery has a ventilating opening through which the battery can "breathe". To exclude an electrolit exit, it is not necessary to incline the battery on a corner more than 45 °.

      •  For a charge of the battery ordinary chargers can be used. The battery can be charged also the device for a fast charging. In this case the battery for a charge is necessary for removing.

      •  If the electronic device is applied to a charge, the battery can not remove and be not to disconnected. Electronics of the charger protects the battery from tension throws.

      •  It is necessary to apply only the electronic device to a charge of strongly discharged battery. At a charging ordinary devices the initial current of a charge is very high that can lead to damage or even to the battery category.

      •  At low level of electrolit, for example after long stay in areas with hot climate, it is necessary to fill in the distilled water in the battery.

      •  If the car is not maintained, it is necessary to charge the battery each six weeks.

      •  If the car is not maintained more than six weeks, remove the storage battery and store it charged. The recommended temperature of storage of the battery from 0 ° to +27°С. At this temperature the battery is discharged in the minimum degree. Not later than in 3 months the battery is necessary for charging. Otherwise it can fail.

      •  Regularly clear poles of the battery and grease them with vaseline or greasing for plugs.

      •  Start from the extraneous storage battery should be carried out in exceptional cases since in this case the battery is exposed to influence of very big short-term overloads.
