Section 10 - Stability and Reactivity
Conditions to be avoided
：
If a number of cells are mixed up without insulating terminals,
they may short and possibly heat, break and ignite. When a
cell is charged, possibly in bursting the electrolyte etc. Or, it
may possibly burst or fire. If a cell is heated or thrown into
fire, it may explode or fire with the electrolyte etc. bursting from
inside of the cell.
If decomposed, there is a possibility of overheating or fire due
to short circuit, and ignition of some material around etc.
Section 11 - Toxicological Information
There is no toxicity because chemical substances are hermetically sealed in a metal vessel.
As a reference, chemical substances composing a cell are described below.

Section 12 - Ecological Information
No information as batteries.
Section 13 - Disposal Precautions
Disposal of the substance should be done according to the laws and regulations.
Although used cells can be discarded basically as “nonflammable refuse,” some local governments
sort and collect them at their own discretion. Therefore, observe instructions of the government you
belong to, to dispose of the substance. Keep the following discarding precautions：
・Even a used cell sometimes stores electric energy. Therefore, to prevent the battery from short-circuit,
isolate cells from each other by a method such as taping +, - terminals of cells, or using the individual
housing case of a cell, used when you bought the battery, and orderly encasing batteries in a box,
then submit an application of disposal to the local government of your residence, using the
designated form.
