Dry-charged car battery check battery

For wet batteries (lead-acid dry-charged car batteries), the density of the electrolyte should be adjusted according to the standards in different regions and different seasons. Distilled water or special rehydration should be added when the electrolyte is deficient. Never use pure drinking water instead, because pure water contains many trace elements, which will cause adverse effects on dry-charged car batteries.

In addition, during daily driving, you should always check whether the small holes in the battery cover of the dry-charged car are ventilated. If some small holes in the battery cover of the car are blocked, the generated hydrogen and oxygen cannot be discharged. When the electrolyte expands, the dry-loaded car will be discharged. The battery shell is broken, which affects the life of dry-charged car batteries. Finally, you should always check the positive and negative electrodes of the battery for signs of oxidation, and sometimes use hot water to often pour the battery wire connection.
