PURPOSE:To increase the surface area of reaction, and thereby enhance the efficiency of a charging of a lead acid battery which is carried out by an intermittent feeding system, by making the internal pressure of the battery to be decreased during the breaks between the feedings. CONSTITUTION:...
During charging, these batteries produce oxygen and hydrogen by the electrolysis. When a lead acid battery cell “blows” or becomes incapable of being charged properly, the amount of hydrogen produced can increase catastrophically: Hydrogen is not toxic, but at high concentrations,...
PROBLEM TO BE SOLVED: To provide excellent cycle life by controlling charge voltage to be a specific value or under when the discharge depth of a lead-acid battery being equal or lower than a specific ratio of rated capacity, the lead-acid battery provided with a positive electrode grid of ...
Method for charging lead-acid battery and charging apparatus using the method In a method for charging a lead-acid battery having a non-antimony-lead alloy grid, after charging the battery, the battery is incidentally discharged in such a manner that the voltage of said battery which has been...
SOLUTION: At the time of charging a lead-acid battery, the charging current is cut for the predetermined time with the predetermined interval during the charge. A voltage difference between the time just before cutting the charging current and the time after the predetermined time is passed is ...
PURPOSE:To prevent overcharge by low DC charging voltage at the time of a high temperature, and to obviate insufficient charging by high DC charging voltage at the time of a low temperature by charging a lead-acid battery by DC charging voltage having a negative temperature gradient in accordanc...
PURPOSE: To provide a charging system for lead acid battery in which selection is made automatically and optimally between normal charging and uniform charging depending on the temperature of the lead acid battery at the time of charging(while taking account of season or region) so that optimal ...
