Shipping lithium batteries has become a confusing issue. Let’s start by asking "what is a lithium battery?". There are two types of lithium batteries – metal and ion (polymer). The lithium metal battery is also termed "primary" which means non-rechargeable. Typically you find these batteries in watches, calculators, cameras, etc. Lithium ion (and polymer) are "secondary" or rechargeable batteries. These are found in mobile phones, laptop computers, satellite navigation units, etc.
