Online UPS is the one which gives output all the time from
battery whether there is power failure or power on. You
get backing from battery all the time.
Offline UPS supplies Mains to the output when power supply
is regular and charges batteries as well at the same time.
When power fails it switches those batteries to produce
output for power backup.
