Warnings and Cautions in Using the Battery

To prevent a possibility of the 21700 lithium cells from leaking, heating or explosion please observe the following

Precautions:

1. When using new 21700 lithium ion cells for the first time or after long term storage, please use the battery charger
2. specifically for that purpose fully charge the battery before use.
3. Do not disassemble or open, crush, bend or deform, puncture, or shred;
4. Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to
