Abstract: The sodium sulphate in the electrolyte and its influence on the electrochemical characteristics such as capacity, reserve capacity, cold cranking ampere, high rate discharge and charge acceptance of the lead acid battery have been investigated.
To de-sulfate a lead acid battery, assume sulfation exists and apply a charge of 2% – 3% of C20 in Amps for 24 to 48 hours. The batteries should not get hot during this process. If necessary, place the sealed lead acid battery in some water, ensuring water does not get too close to the top of the battery.
The total quantity of voltage discharged by the sodium sulfate additive electrolyte (0.80V) was less than that of the dilute sulfuric acid electrolyte (1.20V) and this implies that the additive slightly improved the cycle life of the battery.
The sodium sulphate in the aqueous sulphuric acid electrolyte acts as buffer solution and also expected to improve the reversibility of redox reaction in the lead acid battery. Further, the density of the electrolyte changes with Na2SO4concentration in the electrolyte and the same is depicted in Fig.2.
Additive effects of aluminium sulfate in the sulfuric electrolyte solution of lead acid battery had no improvement on the charge cycle and stability of the cathode with reference to the battery made of dilute sulfuric acid electrolyte.
Lead acid battery due to its nature is bound to experience sulfation. Let us look at common causes that lead to sulfation in a battery. Leaving the battery idle for long time is the biggest reason behind sulfation. It is recommended to start the car battery or a two wheeler for at least 15 to 20 minute every week or two.

Sulfation is a natural chemical process that occurs when lead sulfate crystals build up on the surface of a lead-acid battery''s electrodes during use. This buildup happens because the chemical reactions that produce electricity in the battery also produce lead sulfate crystals, which can accumulate over time. The buildup of lead sulfate crystals can reduce the …
