Flooded lead acid batteries contain a liquid acid solution that is critical to the battery''s performance. The acid concentration is determined with a tool called a hydrometer; the hydrometer measures density, or specific gravity.
When the specific gravity of a battery goes low, it may lead to severe issues and damage the battery. The only thing you have to do is increase it by raising its electrolytes'' acid concentration. You can do this by adding more battery acid into it, which will make the acidity of the electrolyte more potent, raising the specific gravity of the battery. In case the battery''s specific gravity
Flooded lead acid batteries contain a liquid acid solution that is critical to the battery''s performance. The acid concentration is determined with a tool called a hydrometer; the hydrometer measures density, or specific gravity.
