What are the hazards of battery over discharge?
When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.
The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.
Excessive discharge can seriously damage the battery's electrical performance and cycle life.
Crystalline conductivity is poor, and bulky, will clog the pores of the battery plate, affecting the battery electrolyte penetration and exchange, but also further increase the battery resistance, a long time will prevent the battery power and chemical energy Of the reversible conversion, resulting in poor recovery of the battery charge, the battery was seriously damaged, or even unable to repair until scrapped.
