Precautions for handling Small Li-Ion rechargeable batteries
 Hazardous• Since chemical components are sealed in a new electric storage device, thehazards are extremely low.
• However, if you mistakenly use it, the new electric storage device may cause
deformation, leakage, rupture, heat generation, or irritating gas or corrosive gas,so please be extremely careful in handling.
 Stability and reactivity• When two or more devices are randomly mixed without insulation treatment on
the terminals, there is a possibility of bursting and rapid heat generation by
short-circuiting.
• When overcharged, heated, or dropped in a fire, electrolyte or other substances
may burst out rapidly.
• When disassembling the device, there is a possibility of rapid heat generation
due to a short circuit.

P.60

Precautions for handling Small Li-Ion rechargeable batteries
・Do not short circuit the battery
Overheating of the cell may cause leakage, overheating, or explosion.
・Do not apply current via reversed polarity
An abnormal reaction may occur internally, causing leakage, overheating,or explosion.
・Do not apply physical load.
If excessive force is applied, the parts will be damaged, causing electric
shock, short circuit, or liquid leakage.
・Do not conduct the tests listed below
Overcharge test, overdischarge test, nail penetration test, crushing test,
drop test, chemical resistance test, high temperature exposure test.
Treatment when electrolyte leaks
The electrolyte is flammable and is a liquid with irritation to the eyes, skin and mucosa. If leakage
occurs, please take below measures.
・When adhering to the skin
Immediately wash the adhering part with water or tepid water by using soap. If there
is a change in your skin or pain continues, please consult your doctor immediately.
・When gets into eyes
Wash your eye with clean water for 15 minutes and submit to medical treatment.
・Smoke or fire
Please extinguish with carbon dioxide, powder fire extinguisher, or a lot of water.
P.61

Storage of Small Li-Ion rechargeable batteries○ Storage condition
・Please do not let the terminals contact with each otheror contact with the conductors.

・Please avoid storage under the following circumstances.
(a) Being exposed to water, high temperature & high humidity atmosphere,
or condensation of moisture.
(b) Being exposed to oil or an atmosphere that is filled with particles of oil.
(c) Being exposed to salty water or an atmosphere that is filled withparticles of salt.
(d) In an atmosphere filled with toxic gasses (such as hydrogen sulfide,sulfurous acid, nitrous acid , chlorine, bromine, methyl bromide, ammonia, etc.)(e) Being exposed to direct sunlight, ozone , ultraviolet ray, or radiation.
(f) Being exposed to acidic or alkaline solutions
・Long term storage performance is being confirmed.
