Warning

The safety warnings below pertain to all unprotected lithium ion cells (the/this battery). The most common cause of a battery-related fire is a SHORT CIRCUIT.

What is a short circuit?  The situation arises when battery positive (+) and negative (-) directly connect. The current will become extremely high because there is no resistance in the path to limit current flow. A short circuit will result in dangerously high temperature which may cause a fire resulting in personal injury, property damage or death.

While the top cap is the positive pole, the ENTIRE BODY of a cylindrical lithium ion battery is the negative ground pole. ALWAYS keep the protective PVC shrink wrap and top cap insulator in PERFECT condition. DO NOT use the battery if these parts are damaged in any way or if the cell body is dented, deformed, leaking, or damaged in any way.

Keep lithium ion batteries AWAY from metal objects. DO NOT store lithium ion batteries loose or on your person, in a pocket, purse, backpack, etc without a protective box or case. ALWAYS store lithium ion batteries in the box or case in which the batteries were delivered.

If your skin or eyes have come into contact with battery electrolyte, flush with water and seek immediate emergency medical care!
