Primary analysis of factors influencing float voltage of VRLA batteries
Li Zheng and Zhang Gongzheng Weihai Wenlong Battery Co.,Ltd.(Wendeng,Shendong 264423)
By measuring the cadmium voltage of positive and negative plates it has been found that the poor uniformity of float voltage of VRLA batteries mainly results from uneven potential of negative plate.The main factors influencing the drift of negative potential and the measures to be taken to relief the potential from the influence have been analyzed and discusssed,moreover,the effect of gas recombination efficiency on float voltage of VRLA batteries was also explained in detail.
