Warning

1.  Before use, you must read the specification in detail and have a sufficiently deep understanding of the contents of warning and precautions.
2.  It is strictly forbidden to overheat the battery. It is strictly forbidden to modify or disassemble the battery. These actions are very dangerous and may cause the battery to catch fire, leak,explode.
3.  It is strictly forbidden to expose the batteries to extreme heat or to throw them into the fire, and do not put the batteries in direct sunlight.
4.  It is strictly forbidden to directly connect the positive and negative poles of the battery with metal or other wires to form a path, which will lead to a short circuit of the battery.It may cause the battery to catch fire or even explode.
5. It is strictly forbidden to use the positive and negative poles upside down.
6. It is strictly forbidden to immerse the cell in water or other conductive liquids, or make it hygroscopic
7. It is strictly forbidden to subject the cell to excessive mechanical shock.
8. It is strictly forbidden to solder the battery directly, high temperature may cause deformation of battery parts (such as gaskets), which will cause the battery to swell,Liquid spills, fires and even explosions.
9. It is strictly forbidden to use batteries that are squeezed, dropped, short-circuited, leakage and other abnormal problems during transportation.
10. It is strictly forbidden to directly contact the shells between batteries or connect them together to form a path through the conductors during use.
11. Batteries should be stored away from static electricity.
12. It is forbidden to use the battery with other primary or secondary batteries, or with different packs, different models or other batteries.
    Use with other brands of batteries.
13. During use, charging and discharging, or storage, the battery is found to heat up quickly, emit odor, discolor, deform or other
    If a reaction occurs, discontinue use immediately and treat accordingly.
14. If the battery is spilled on the skin or clothing, please rinse with water immediately to avoid skin discomfort, etc
