Waste not

The Eco Clock solves a battery waste problem in a smart way. There are many instances where devices that use AA batteries stop working long before the battery or batteries have run our of juice. The Eco Clock allows you to place an almost dead battery in each slot where the hour indicators would be. You can fill as many slots as you like and the clock will use the batteries in tandem. Plus, as each battery goes completely dead, it can indicate that as well.

What a great way to get every last ounce of electricity out of your AA batteries. Prepare for some major Engrish at the link.
