"Loss of power" is a kind of damage to the battery plate coating caused by excessive discharge when the battery is low and the voltage is low. The working voltage of any vehicle mounted appliance has a standard range, more than this range, electrical appliances short circuit or even burn down, below this range, electrical appliances can not start or work properly, and even affect the service life.The occurrence of electricity is not the case, mostly because the battery for a long time from the discharge, resulting in loss of electricity, or generated by the formation of sulfide. As l...
