Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.

A lead-acid ...
The loss of electrolyte in a flooded lead acid battery occurs through gassing as hydrogen escapes during charging and discharging. Venting causes the electrolyte to become more concentrated, and the balance must be restored by adding clean water. Do not add electrolyte as this upsets the specific gravity and shortens battery life by promoting ...
"If you filled a new lead battery with a magnesium sulfate solution instead of sulfuric acid electrolyte, it would have no capacity at all." Simply put, adding Epsom salt will not recover the battery capacity but does "artificially" increase the SG.
Creating a lead-acid battery electrolyte solution is like mixing ingredients for a recipe. You need sulfuric acid and water in the right amounts to make the battery work well. Scientists are always looking for new ways to make batteries better and safer. By using safer materials, like non-flammable electrolytes, batteries can be safer for ...
Do not smoke when activating a battery or handling battery acid. Always wear plastic gloves and protective eye wear. Fill the battery with the electrolyte/battery acid that you purchased along with the battery. Do not use water or any other liquid to activate a battery. Electrolyte should be between 60 and 86 degrees Fahrenheit before filling.

Use of Electrolyte in Battery . In a lead acid battery, the electrolyte is a mixture of water and sulfuric acid. This mixture allows for a chemical reaction to take place between the lead in the electrodes and the sulfuric acid, which creates an electric current. The electrolyte also helps to keep the lead electrodes from corroding.
When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged.

The electrons enter the negative terminal and re-join with the lead sulphate, releasing the sulphate into the electrolyte to leave just lead on the negative plate. The sulphate ions enter the electrolyte and combined with the hydrogen ions to release the oxygen ions, and so the electrolyte acid becomes stronger.
While this is true, it can also lead to battery stratification – which causes the battery acid to separate from the electrolytes and collect at the bottom of the battery. This leads to sulfation which, as mentioned earlier, leads to decreased battery performance and a shortened life cycle. So, what does this all mean?
A flooded lead-acid battery has all the indicted domains, but a VRLA does not have an electrolyte reservoir because the electrolyte is immobilized in the separator. The charge, mass, and momentum transport equations that describe lead-acid batteries are summarized in Table 4 .
