Can a $2.50 gadget extend alkaline battery life by 800%?

[quote=“beschizza, post:1, topic:58807”]Here’s the patent.[/quote]No, no, no. That is a PUBLISHED PATENT APPLICATION. That is not a patent. The USPTO will publish just about anything with the appropriate fees. It is no more patented than John Quincy St. Clair’s Magnetic Monopole Spacecraft.

You can look up the application number at Patent Application Information Retrieval and see that it does not look like the patent will be granted anytime soon.
