There is something you can do, you have to purchase a battery charger for batteries of higher Ah ratings.
Then working with little circuits (relays ans transistors)(you have to do it yourself with a little internet help).
Now you can use external chargers for charging and discharge it using UPS. This extends the backup time, but computer UPS are not applicable to celling fans or so. TAKE CAUTIONS YOU MAY LOSE YOUR UPS IF NOT USED ON SPECIFICATION RATING).
THESE ARE VERY DELICATE MACHINES.
THANKYOU

If a shunt Dynamo has induced emf 100V and 0.4 ohm resistance and battery of accumulator of open circuit emf 110V and 0.5 Ohm resistance are in parallel what is common terminal potential difference?
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
