Need a better battery.

I have a project to decorate the family "Little Red Wagon" with
Christmas lights. So I stated experimenting with LED light strings and
battery combinations. I finally decided to use an Inverter and not
cut up any light strings. The LED light set that I found has 80
lights and the specs state it uses 12 watts. So as a test I connected
two 6v lantern batteries in series and ran the leads to the inverter
(rated at 100watts), connected a lamp with 40 watt bulb.
80 watts at 120 volts is the same as 960 watts at 12v. add in the losses in
the inverter, and you're gonna need a large battery
