Hmmm… My UPS is not functioning properly!!!.. Battery Cancer!!! and so my system in CCU. The symptoms are
-Taking too much time for switching between mains and battery
-Even with sufficient voltage, its taking power from battery and giving Beep Beeeeeeeeeeep since my battery is more than 2 years old.
-Battery is not at all charging
Tonight I am planning to perform a curative surgery on my UPS.
