Unhappy HTC Universal battery not detected

Hello everyone I have a HTC universal and I bought a extended battery.
Everything worked fine until it showed 0 percent ,after that, most of the time it had the red light that means no battery. I switched to original battery and then it worked again, after some time it started booting , red light , booting again while connected wall charger. Right now it is that cycle it gets to the windows mobile screen (WM5) red light and then boots again
