Periodic check and restoration of the electrolyte level.
Checking the condition of the battery case by inspection.
Battery cleaning, corrosion removal (white deposits) on battery mounting parts and terminals (photo) aqueous solution of soda ash.
Checking the reliability of fastening the terminals on the poles.
Checking the battery charge with a hydrometer. Maintenance-free batteries have a built-in color indicator. A blue dot in the indicator window indicates that the battery is fully charged, when the indicator turns off, the battery should be charged.
8.6 Retightening the battery terminal
7.4b If air does not pass through the valve, then fix the leak by spraying the tire with soapy water
7.8 Checking tire pressure with a pressure gauge
The normal density of the electrolyte at 27°C is 1.27 (with a correction of±0.04 for every±100).
The battery is considered partially charged if the density of the electrolyte at 27°C is 1.240.
The battery is charged with a current of 4-6A. Charging stops 3-4 hours after the battery voltage stops rising.
8.7a Battery terminal corrosion
8.7b Removing the terminal from the battery
8.7c Clean the battery pole to a shiny surface
8.7g The terminal should also be thoroughly cleaned without removing excess material
