UPS shuts down when the mains is off.
After 3 years, i would by a new UPS...
The battery will have to be changed if you want to keep the old one.
What i've seen mostly here in south africa. When the battery life has ended they customer opens the ups and takes out the battery and then connects a car battery to the terminals. The then close the ups and let the car battery stand outside the ups.
Hope this info helps...
