150ah

I need an inverter for home for minimal needs.. It should power 2 lights, 2 fans, a laptop and a wifi router. 600VA with 150Ah batteries would be more than enough? Would need backup for 2 hours. Budget: 6-7k. Suggestions please.

We have 600VA digital home UPS with 50AH tubular battery. Now looking for higher rated (150AH) battery. I have asked for quotation (ranging from 12k to 17.5k - non-tubular and tubular) from several brand distributors now I am little confused with which one I should pick up... Amaron Microtek...
