Although batteries are safe to use under normal conditions, improper handling may result in a personal injury or equipment failure from heating, electrolyte leakage, rupturing or fire. For safe to use of batteries, be sure to follow the instructions below. With regard to rechargeable batteries, follow the instructions printed on battery casing and packaging paper card.
1. Observe the following precautions to ensure safety.
(1) Electrolyte First-Aid
Be careful not to directly touch any electrolyte leakage from a battery.
If the battery electrolyte leakage contacts your clothing or skin, it may damage the clothing or corrode your skin. Should it get into your eyes, it could cause loss of eyesight. If alkaline electrolyte in particular gets into your eyes, immediately rinse them with plenty of water and seek medical advice. If licked, immediately rinse your mouth with plenty of water and seek medical advice. If the electrolyte leakage contacts your clothing or skin, flush the affected area repeatedly with water.
Do not charge batteries (except rechargeable batteries).
Do not attempt to charge primary batteries, because they are not designed for charging. If an attempt is made to charge them, gases generated within the battery can cause overheating, rupturing or fire.
Do not short-circuit the positive (+) and negative (-) terminals.
Do not connect the positive (+) and negative (-) terminals of a battery with a wire, or carry or store batteries together with metal necklaces, hairpins, coins or other metallic objects in order to avoid a short-circuit. If short-circuited, excessive current will flow, possibly damaging the battery structure due to the generated heat, with the possible result of overheating, leaking, rupturing or fire.
Do not attempt to disassemble a battery.
Do not attempt to peel off or impair the battery outer tube or the label. If you attempt to disassemble a battery forcedly, you can get your hands or fingers injured. If the electrolyte inside the battery gets into your eyes or adhere to your skin, you can get your eyes or skin injured. Do not allow leaked electrolyte to come into contact with the human body. If this happens, rinse with a large quantity of water immediately. Alkaline primary batteries contain a strong alkaline acid, which can corrode your skin or cause loss of eyesight. If a manganese dioxide lithium primary battery is disassembled, the internal metallic lithium is exposed, which reacts violently on contact with water, causing fire hazard.
Do not deform a battery.
If you deform a battery by excessive pressure, the seals may become warped and cause leaking, an internal short-circuit, or other abnormalities. An internal short-circuit or other abnormalities can cause overheating, leaking, rupture or fire.
Do not cause the battery to become heated.
If the battery is heated, the insulator, the gas exhaust valve or other parts may be damaged, possibly causing leaking, overheating and rupturing.
(7) Disposing of in Fire
Do not throw a battery into a fire.
A battery may rupture or burn violently when thrown into a fire. This can be more dangerous than the events described in paragraph 6.
Do not directly solder anything onto the battery terminals.
Direct soldering onto the battery terminals causes the battery to be heated, and the events described in paragraph 6 can occur as a result.
Do not give a strong impact to a battery.
If a battery is fallen, thrown or otherwise given a strong impact, the insulator in the battery or its structure may be damaged, possibly causing leaking, an internal short-circuit or other abnormalities. An internal short-circuit can cause overheating, leaking, rupturing or fire.
(10) Reverse Battery
Insert a battery with the positive (+) and negative (-) terminals oriented correctly.
If a battery is inserted with reversed terminals, abnormalities can occur due to charging, a short-circuit, etc., with the possible result of heat generation, leaking, rupturing or fire.
If an electric circuit is left connected (e.g., you forget to turn off the power switch) after equipment has entered an unoperational state, a battery continues to be drained, leading to an overdischarge situation. Consequently, gases generated within the battery can cause leaking or rupturing, or damage the equipment. If two or more batteries that are connected together are overdischarged, the battery voltage can drop below 0 V (as a result of polarity inversion), further increasing the possibility of leaking or rupturing.
(12) Mixed Use
Do not mix different types of batteries together, and do not mix used and new batteries.
Your equipment may not operate properly if batteries of different voltages and types are used together. In addition, the battery exhausted first may be excessively drained (overdischarged) due to different discharge characteristics, which may eventually result in leaking or rupturing of the battery. When used, new and/or partially used batteries are used together, used and partially used batteries will be excessively discharged. This is not only uneconomic but also may cause the battery to leak or rupture. Replace all batteries with new batteries at the same time.
2. Observe the following safety precautions to prevent batteries from being swallowed.
Small-size batteries (e.g., AAA size, N size, button cells, coin cells) can easily be picked up by little children and swallowed. Keep all batteries out of reach of little children. Consult a doctor immediately if a battery is swallowed.
Storing the Thionyl Chloride Lithium Batteries
The service period of the Toshiba Thionyl Chloride Lithium Batteries are within 10 years, although it is not a guaranteed value. The service period is equal to the total of the storage period and the actual conducting period. This suggests that the number of years as counted from the time of production should not exceed 10 years when you set the storage period. Also note that the guaranteed period of Toshiba Thionyl Chloride Lithium Batteries are one year.
Please note that we would not be responsible for any damage from the use exceeding that year. As the storage period is prolonged, the film formation on the lithium surface will grow accordingly, thus leading to a voltage drop known as the voltage delay phenomenon. Any prolonged storage should be avoided because such a voltage drop might cause malfunction, although the situation varies depends on device usage conditions (such as the environment and current value).
We also recommend that you will start using the battery sometime within one year after purchase.
