Sheng Lee Electronics teach you the battery Caution Simply speaking: ground charging shallow discharge! Day with a day charge! 1, to prevent over-discharge battery discharge to the termination voltage battery car charger, continue to discharge as discharge. 2, to prevent over-charging has on the front were described overcharge, over-charging batteries will increase water loss will accelerate grid corrosion car battery charger supplier of the active substance to soften, will increase the chances of battery deformation. Lee Sheng Electronics Factory teach you the output DC voltage is too low causes: 1: end of the rectifier output voltage tripolar Chu, filter capacitor failure, can be judged by the substitution method 2: performance switching power tube car battery charger decline Which is good, not normally cause the switch is turned on, the internal resistance of the power increase, with a load capacity decrease. Which car battery charger | Lee Sheng Electronics Factory grade quality | Fujian car battery charger provided by Lee Sheng Yongkang Electronics Factory.
