Cleaning the terminal from corrosion
Cleaning the pole piece
Battery maintenance consists of checking the condition of the poles and terminals, the presence of electrolyte leaks and corrosion on adjacent metal parts, restoring the electrolyte level, periodically checking the voltage and charging. Corroded areas should be washed with a soda solution and painted with zinc primer. The terminals and poles should be cleaned until shiny, without deforming the conical part of the terminals. For maintenance-free batteries, check the density of the electrolyte. Some batteries have built-in chromatic hydrometers.
Built-in chromatic hydrometer
1. White (needs to be recharged)
2. Blue
Distilled water should be added (if there are no electrolyte leaks) until the level reaches 9.5 mm above the plates.
Charge the battery (except for unattended) low current is recommended.
