Answer / jayaraj

You have to increase the AH of the battery. Make sure that the charger of the UPS have enough capacity to charge the batteries.

Answer / nayan

if we attached another battery with ups then then the backup
time increased or if we attached a higher AH battery then
backup time increased. but if battery is higher AH that time
may be another charge controller assigned to reduce time of
charging and prevent the damage of UPS.

Answer / ram

If changing hardware is a constraint then UPS battery time
can improved by reducing the load connected to the ups !..

Answer / manoj

Ups- back can be increase by increasing the AH capacity of
battery or by increasing no. of battery unit.
