Avoid sulfation for ordinary batteries, if they are in an overcharging mode or undercharging mode for a longtime, it will make the battery lose its internal water and lead to sulfation, thus greatly shortening charger's operating lifetime. But can solve batteries' problem of imbalance derived from longtime overcharging and undercharging, thus avoiding internal sulfation of the battery, restoring batteries' capacity and extending their operating lifetime.

避免硫酸盐化--普通电池如果长期处在一种过充电或欠充电状态中，会使电池内部不断失水和硫酸盐化，这样就会大大缩短充电器使用寿命，可是，它能解决电池长期过充电和欠充电引起的失衡，避免电池内部硫酸盐化，能够恢复电池容量，从而延长它的使用寿命。
