RITARups蓄电池RA12-65(12V65AH)停电后可以延时供电60分钟为负载应急工作提供可靠保障，快速充电的分类：

　　①恒定电压法。恒定电压法是在确定并保持充电电压为某一恒定值的情下，所进行的充电方法。此电压值应选取与蓄电池充电过程中出气点相应的电压值。

　　②恒定电流法。恒定电流法是在充电过程中不断保持充电电流恒定的充电方法。为实现快速充电，必须采用较大的电流进行充电，因此造成充电后期南都蓄电池大量出气，过量出气是不允许的，所以一般不采用。

　　(3) phase charge method.Including two - stage charging method and three - stage charging method.The two-stage charging method generally adopts the quick charging method combining constant current and constant voltage.First charge at a constant current to a predetermined voltage, then change to a constant voltage to complete the rest of the charge.In general, the two-stage conversion voltage is the constant voltage of the second stage.The three-stage charging method adopts constant current at the beginning and end of charging, and constant voltage in the middle.When the current attenuates to a predetermined value, the second stage is converted to the third stage.This method attenuates the air output to a minimum, but is limited as a quick charging method.

　　(4) Reflex fast charging method.Reflex, a cycle of the Reflex mode, consists of three modes: Reflex charging pulse, Reflex instant discharge pulse, and Reflex pulse for maintenance and detection.

　　(5) variable current intermittent charging.It is based on constant current charging and pulse charging, and its characteristic is to change the constant current charging section into the intermittent charging section with limited voltage and variable current.In the early stage of charging, variable current intermittent charging is adopted to ensure that the charging current is increased to obtain most of the charging amount.At the later stage of charging, the constant voltage charging stage is adopted to obtain the overcharge amount and restore the battery to the full charging state.
