While writing reviews of products I often run into new terms that aren’t explained well. Acutally, I run into new terms with almost every product I wrestle out of its packaging. The i-Fusion review presented me with a new twist on batteries, the three phase lithium ion rechargeable battery. I undertook a search to discover what is different about a 3-phase battery. In my search I uncovered a nice site that actually explains in detail about the myriad of batteries we now use on a daily basis. I didn’t uncover the secrets of a three phase battery, but I certainly learned a few new tricks about battery life.

The site is actually called Battery University, published and sponsored by Cadex Electronics Inc. “The material is based on the book Batteries in a portable World – A handbook on rechargeable batteries for non-engineers, and is written in condensed form.” The text is easy to read, and all those voodoo-ish terms we see tossed around concerning the most common component of our plugged-in lives are explained.

Other sites that contribute useful knowledge to your battery gray matter are Wikipedia, the free encyclopedia and of course Apple’s page on Lithium-ion batteries.
