2. Corroded areas should be washed with a soda solution and painted with zinc primer. The terminals and poles should be cleaned to a shine, without deforming the conical part of the terminals. When cleaning, remove all corrosion.
3. Charge the battery (except for unattended) it is recommended to charge the battery with a current of 2 A for 12-16 hours. To check the capacity, it is recommended to charge the battery with a current of 1/10 of the capacity expressed in ampere-hours.

4. Check the density of the electrolyte. Some batteries have built-in chromatic hydrometers. The density of the electrolyte in such a battery is determined by the color chart supplied by the manufacturer (a dark color of the indicator usually indicates a completely discharged battery).
