[Danger! ]

1. Electrical misusage

• 1.1. Use or charge the 21700 rechargeable li-ion battery only in the stipulated application.
• 1.2. Use the correct charger for Lithium-ion batteries.
• 1.3. When connecting a battery pack to a charger, ensure correct polarity.
• 1.4. Do not reverse charge lithium ion battery 21700.
• 1.5. Do not maintain secondary 21700 lithium ion batteries on charge when not in use.

2. Environmental misusage

• 2.1 Never put a battery into water or seawater.
• 2.2 Don't throw the lithium 21700 battery into the fire.
• 2.3 Do not use or leave the cell under the blazing sun (or in heated car by sunshine). The cell
• may generate heat, smoke or flame. And also, it might cause the deterioration of cell's
• characteristics or cycle life.
• 2.4 Do not dismantle, open or shred cells. Batteries should be dismantled only by trained
• personnel. Multicell battery cases should be designed so that they can be opened only
• with the aid of a tool.
• 2.5 Do not solder directly to batteries.
• 2.6 Do not subject batteries to adverse condition such as extreme temperature, deep cycling
• and excessive overcharge/over discharge.
• 2.7 Do not short-circuit batteries. Do not store batteries haphazardly in a box or drawer where
• they may short-circuit each other or be short-circuited by conductive materials, permanent
• damage to batteries may result.
• 2.8 Do not incinerate or mutilate batteries, may burst or release toxic material.
• 2.9 Do not subject batteries to mechanical shock.
