1. maintenance-free lead-acid battery, which is sealed and designed for PS(Instant Power Supply) ,EPS(Emergency power supply)，UPS (Uninterruptible power supply system), and other floating occasions.Rated voltage: 12 VRated capacity :65AhMax discharge(A) :800AOutside Dimensions ：210 165 180mm KGS : 22.5 kg we also produce batteries for specific designs and applications and we can also supply various battery according to the requirements of the customers.2.Inverter Power Supply can alter the 12Vor 24Vdirect current which is provided by battery into altering current 220V. While it will transform the city power into direct current electricity to charge the battery .In simple words, no electricity, the inverter output; there is electricity, electricity output, at the same time to recharge batteries.This machine, which with a ring transformer, can make the inverter, charge and regulating voltage together. It has the following characteristics: high efficiency, energy conservation, frequency stability, small loss and automatic switching.IPS—500W,12V,60AH；750W,12V,100AH;1500W,12*2V,100AH
