Description: This is a very small, extremely light weight battery based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 110mAh! Comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins. These batteries require special charging so please do not attempt to charge these with anything but a specialized Lithium Polymer charger.
Each battery includes a built-in protection against over voltage, over current, and minimum voltage. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.

Sparkfun changed the distributor while not updating the new batteries' dimensions. When we tried to return the batteries Sparkfun would not accept our return or credit the order. Now we have batteries that do not fit and can not return them or use them.
