Battery.. invertor for a fan.... need help..!

Hi, I want to power a table fan (50 watts) using a battery. In India the input power to appliances (fan in this case) is 220 volts / 50 Hz. so can i power the fan with TWO 6 volts 4.5 AH sealed lead acid battery??
Can u please tell me how to do the power calculations? i want my fan to run for abt 4 hours. how many batteries do i need?

(im planing to charge the battery using solar panel but thats another question)

Why not use a 12 volt DC fan such as sold for dash board use in motor vehicles.

Examples: Metal Blade 12-Volt Fan - Intersource Enterprises D10-123 - Fans - Camping World
