Notes
Battery operation precautions: Do not touch the aluminum foil packaging material with sharp objects, do not bend the top edge seal, do not open or damage the folded edge, do not bend the fragile tabs, do not drop, impact or bend the battery, and at no time should the battery be short-circuted or the positive and negative terminals be reversed.
Other matters: Prevent short circuits inside the battery packaging. Do not disassemble the battery. Do not throw the battery into fire. Do not immerse the battery in liquids (such as water, beverages, fruit juice, coffee). Do not replace the battery by yourself. Do not use damaged batteries.
The power consumption of all products in our factory is the actual standard. The specific usage time depends on the power consumption of the equipment.
