Problem with ups #1
Salam brothers i have an Apc Ups model no DLA1500RM12U and i am using it with two Phoenix 102a liquid acid batteries. I have been using it for almost an year now with no problems but recently it has started malfunctioning Whenever the electricity goes out the battery level indication falls from 5 green points (showing fully charged) to just one. Then it runs for almost 40-45 minutes before shutting down. There is not much load on it just running one Computer. Please suggest any remidies?
Problem with ups#2
One more question i have another APC ups model of the same capacity attached to two dry batteries (Big ones not sure of their power) and it does the same thing ..battery indicator falls from fully charged to 1 point suddenly when the light goes off and shuts down after 20-25 minutes...Please suggest me if the batteries of both UPS need to be replaced they are just an year old or is it the ups malfunctioning ( i have tried switching upss same result) not sure if they both need software overhaul or if the batteries are done.
