Cautions and Warnings

• Never mix old and new batteries.
• Never mix different types of batteries.
• Never mix batteries from different manufactures.
• Do not drop the battery, as internal damage may occur.
• Only replace or charge the battery pack in a non-hazardous location.
• Never mix batteries with different chemistries.
• Do not store the battery in the equipment.
• Do not short circuit battery.
• Do not immerse in any liquid.​​
  

Composition ​of a Li-ion Battery

The negative electrode of a conventional lithium-ion cell is graphite made from carbon. The positive electrode is typically a metal oxide or phosphate. The electrolyte is a lithium salt in an organic solvent. The negative electrode and the positive electrode are separated to prevent a short. The electrodes are connected to the powered circuit through two pieces of metal called current collectors. ​

​F​​rom the U​​.S. Environmental Protection Agency

Most Lithium-ion batteries on the market are likely to meet the definition of hazardous waste under the Resource Conservation and Recovery Act (RCRA). Most lithium-ion batteries when discarded would likely be considered ignitable and reactive hazardous wastes (carrying the waste codes D001 and D003, respectively) ... Commercial establishments are responsible for determining whether any waste they produce is hazardous waste, including Li-ion batteries at their end of life.

Lithium-ion batteries with different chemical compositions can appear nearly identical yet have different properties. In addition, some discarded Li-ion batteries are more likely to have hazardous properties if they contain a significant charge, yet such batteries can appear to the user to be completely discharged.
