The low-served rechargeable battery

The car is equipped with the so-called low-served rechargeable batteries. These batteries when carrying out service demand only electrolyte addition.

At the same time it is necessary to follow the following rules:

      •  The cover of the battery has an air vent through which the battery can "breathe". To exclude an electrolyte 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 with the device for bystry charging. In this case the battery for a charge needs to be removed.

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

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

      •  At the low level of electrolyte, 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 operated, it is necessary to charge the battery each six weeks.

      •  If the car is not operated more than six weeks, remove the rechargeable battery and you store it loaded. The recommended temperature of storage of the battery from 0 ° to +27 °C. At this temperature the battery is discharged in the minimum degree. Not later than in 3 months the battery needs to be charged. Otherwise it can fail.

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

      •  Start from the foreign rechargeable battery should be carried out in exceptional cases since in this case the battery is affected by very big short-term overloads.
