What is the charge exchange and how it is harmful?
Overcharge - a continuation of the battery or battery after reaching a state of full charge.
Under the influence of recharge is accelerated loss of water from the electrolyte. The electrolyte level is reduced and its density increases, respectively. When the battery overcharge oxygen produced by electrolysis of water penetrating through the layer of active paste to the surface current leads and oxidizes it. Oxidized electrodes of becoming fragile and easily destroyed. In addition, long-term overcharge is excessive gassing, the decomposition of water into hydrogen and oxygen, often resulting in the battery to explode. Overcharging is a consequence of disruption of the voltage regulator.
