Question about APC VS 500VA (VS500VA) UPS System
I have an apc vs 500a battery backup unit. It has started doing something funny. The green light is on. The on battery light blinks yellow along with the green light blinking and it makes noise when doing it. It has been happening more and more throughout the day. Do you know what the problem
It sounds like you may need a new battery. The batteries are continuously tested by the UPS and it could be that the voltage is passing one test, and failing the next which is resulting in the light flashing. You can test the battery with a voltmeter. It should read over 11.5 volts, if not you need a new battery set. You can get batteries from http://www.batteryinternational.com/ups-batteries-apc-batteries.html
