The 2008 Battery Challenge! - Day 4

We are finishing up the battery test for Duracell. More surprises are in store as we find out which big name battery brand gives you the best value for the money.Today we began each toy at 8:06am and at 10:48am the Night Vision Goggles were the first to lose their battery life. The Geo Trax lost power at 10:53am and in this case the screwdriver ran until 11:50am.

Screwdriver - 7 hours 35 minutes
Geo Trax - 7 hours 47 minutes
Night Vision Goggle - 8 hours 24 minutes

How do we find out the best battery life? We take the average price/total running time.

We will use the AC Nielsen Data for the average every day price per 4 pack of batteries.

Night Goggles require 5 AA batteries.
The Home Depot screwdriver requires 2 AA batteries.
Geo Trax requires 6 AAA batteries.
