I have placed many different batteries of the same type and checked the inverter circuit of my br800i (but no evident problem with 4 irf740 and all transistors and zeners and resistors and have changed all of the capaciors coresponding to 22uf/25v to 22uf/50v {because of older age of the ups}) The problem is that my br800i when on shows the green light on after some time and the overload (red) + replace battery (red) +on battery (yellow) ALLWAYS FLASSHING. So: Green-on Yellow-flashing on and of the same time with: Red- flashing Red- flashing ???? What could be the problem?. Cheers Edi Albania
