Hello. I have APC back UPS BE650Y-IN (Model: http://www.apc.com/products/category.cfm?id=13&segmentID=1 select BE650Y-IN from first pulldown menu to see the specification). Its battery is dead now. I have solar system in home. At present it is used for only lights. Solar system has the battery which looks something like this (http://www.apexbattery.com/8a22nf-solar-battery-group-22nf-solar-batteries.html). Now I want to connect the APC UPS to this battery. Is this connection possible?. UPS battery is 12V,3A and Solar battery is 12V,6A (Dont know exactly). Will this connection cause any problem to UPS?. I want to use this UPS for only TV(90W).
