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

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
