To prevent the possibility of the battery from leaking, heating, fire, Please READ this specification carefully before:

usage and observe the following precautions:

◎When recharging, use the LiFePO4 battery charger specifically for that purpose

◎Do not strike battery with any sharp edge parts, such as Ni-tabs, pins and needles

◎Do not immerse the battery in water and seawater

◎Do not use and leave the battery near a heat source as fire or heater

◎Do not reverse the position and negative terminals

◎Do not connect the battery to an electrical outlet

◎Do not discard the battery in fire or heat it

◎The battery tabs are not so stubborn especially for aluminum tab. Do not bend tab.

◎Do not short-circuit the battery by directly connecting the positive and negative terminal with metal object.

◎Do not transport and store the battery together with metal objects such as necklaces, hairpins etc.

◎Do not directly solder the battery and pierce the battery with a nail or other sharp object.
