New batteries requird for a UPS

#1
The batteries which I had for my UPS is now dead and therefore I require new batteries, I would like to get advise ffrom forum members to which batteries I should get or which are the best for my requirements. When the UPS is running I need two tube lights or light bulbs working, during the summer time I need three ceiling fans and possiably a power socket to charge mobile phones or charge a laptop. Sometimes there are electricity cuts for more than 5 hours so batteries whic would last around 6 hours allowing all the devices to be working during the full 5 hours.
