When the sulphuric acid is dissolved, its molecules are dissociated into hydrogen ions (2H+) and sulfate ions (SO4– –) which moves freely in the electrolyte. When the load resistance is connected to terminals of the battery; the sulfate ions (SO4– –) travel towards the cathode and hydrogen ions (2H+) travel towards the.

Get a quoteFreshening Charge – Lead-acid batteries will self-discharge from the day they are manufactured until they are put into service. As it is often several months before the battery is installed, it is important that a "freshening" charge be given before the battery exceeds its storage shelf life. For lead-antimony or selenium, this is usually 3 months, and for lead-calcium, 6 months. Some
