It's capacity as indicated in label is 4 x 12V24Ah. I charged it for 5 hours. How much would be the consumption in watts? How to calculate this?

An input current???? 1.0V .... that "V" means volts

12V 24Ah means this is a 12V battery(you have 4 of these?) which can deliver 24A for 1Hr (or 1A for 24hrs)

12x24 = 288 Watts which one battery can deliver for 1 hr

four of these gives a battery capacity of 1152 W hr...

First the consumption will be in Watt hrs

You need to tell us if the batteries are in series (making 48V) then what is the charging current ....
