Re: CyberPower 1350AVR - Repair



My Cyberpower CP1350AVRLCD would no longer charge the batteries past 50%, even after replacing them with fresh new ones. But then I found this forum. At first I replaced the ST VIPER22 since there was some brown burn marks around it, but that still didn't fix the problem. I then followed tehownt's advice by purchasing new capacitors for C1, C6 (Nichicon 33UF 200V) and C3 (Nichicon 22UF 50V) from digikey and replacing these 3 capacitors. The UPS is now working once again and able to recharge the batteries to 100% even under a load!...
