5. Warning and Attention

HB lithium battery employs substances and made with technology; as a lithium-ion battery, such as other kinds of cells, it has risks when it’s mechanically damaged, although it’s passed UL safety certificate. The following precautions should be taken into consideration when managing and utilizing HB lithium-ion batteries:

It is prohibited to set the cannon and needs to place in a warm and humid environment during storage.

It is not permitted to use from the hot sunshine of moxibustion unless it might lead to battery overheating, fire, or operational failure.

It is illegal to matter an assault or battery pack into mechanical shock.

in case of leakage, don’t contact with the leaking liquid directly into the skin or eyes if contact occurs, use a lot of water to flush out the contact region.

don’t use non-special charging that ought to performed following the manufacturer’s directions.

Notice the”and positive ear” and also”-negative ear” signals of the battery pack to ensure appropriate use.

Maintain the battery pack dry and clean. Use a dry cloth to wash it. In case the battery pack gets dirty.

don’t charge the battery pack for quite a while.

Maintain the initial specification of this item for future reference.
