Storing the car battery Lada Granta

Tool:

• Stationary charger

Note:

Lead-acid batteries should only be stored in a charged state.

At temperatures below -20 ° C, the battery must be charged once a year for 48 hours with a constant voltage of 2.275 V per one battery bank, and at room temperature - once every 8 months for 6-12 hours with a constant voltage of 2.35 V per battery bank. Storage of the battery above 30°C is not recommended.

A layer of dirt and scale on the surface of the battery becomes a conductor for current from one contact to another and leads to self-discharge of the battery, after which premature sulfation of the battery plates begins. This is why the surface of the battery cover must be kept clean (wash before storage).

Note:

Storing lead-acid batteries in a discharged state leads to a rapid loss of their performance.

With long-term storage of the battery and its discharge with high currents (in the starter mode) or with a decrease in capacity, it is necessary to carry out control-training ("treatment") cycles, that is, discharge-charge with a rated current.
