The proper handling of primary batteries
1) Do not reverse the positive and negative terminals
A device that uses three or more batteries may operate even if one battery is inserted reversely. If the battery inserted reversely is recharged, however, it may become hot, leak, or explode.
2) Do not short circuit batteries
Do not carry or store batteries with necklaces, hairpins, coins, keys, or other metallic objects. Metallic objects can cause short circuits in the positive and negative terminals of batteries, resulting in the flow of large electrical currents that can cause heat generation, explosions or fire, or generate heat in the metallic objects.
3) Do not recharge dry or lithium primary batteries
Dry and lithium primary batteries cannot be recharged.
4) Do not use different types or used and new or different brands of batteries together
The use of a mixture of different types or brands of battery, or of used and new batteries even of the same brand or type, may result in heat generation, leakage, explosion, or fire. When replacing the batteries, use new batteries of the same types and brands.
5) When batteries run down, remove them as soon as possible
Remove the batteries as soon as they become run down. Otherwise, the batteries may leak and damage the device.
6) Do not expose batteries to heat or fire
Do not expose batteries to fire. This is dangerous and can result in explosions or fire. Heating batteries may cause them to leak or explode.
7) Do not apply solder directly to batteries
Do not apply solder directly to the terminals of a battery. Soldering batteries is dangerous, because the heat will melt the insulator, creating an internal short-circuit, and leading to heat generation, explosion, and fire.
8) Do not disassemble or modify batteries
Disassembling a battery is dangerous and may result in explosion or fire, and the content may cause chemical burns.
9) Do not deform a battery
Squashing, drilling, or cutting a battery is dangerous as it may result in leaking or exploding.
10) Keep batteries out of reach of children
Keep batteries out of reach of children. In the event that a battery is swallowed, immediately consult a doctor. In addition, do not allow children to remove batteries from devices and do not allow animals to play with batteries.
11) Remove the batteries from devices that will not be used for a long time
Even when the device is turned off, the power in the battery is slowly draining. This may result in leakage, so please remove the batteries when the device will not be used for a long time (excluding emergency devices).
12) Flush with water to remove battery electrolyte from skin or clothing
If the battery leaks and its electrolyte comes into contact with skin or clothes, wash the contact area with clean water. If battery electrolyte gets into the eye, flush immediately with clean water and consult a doctor immediately.
13) Turn off battery-powered devices when not in use
The cause of leakage in many cases is the failure to turn off the device. So please turn off devices when they are no longer in use.
14)Regularly check the condition of batteries used in devices without a power on/off switch (such as clocks, wireless mice and remote controllers)
A device without a power on/off switch constantly consumes and weakens battery power. This may result in the unstable behavior of the device. In such cases, the battery needs to be replaced as soon as possible.
15) Do not store batteries in a location subject to high humidity and temperatures where they are exposed to direct sunlight.
The ideal environment for people is also the ideal environment for storing batteries. High humidity may cause condensation on batteries, resulting in short-circuiting. Leaving a battery in a location subject to high temperatures for a long time will reduce the battery performance.
16) Do not get batteries wet
Getting a battery wet with water, salt water, juice or other liquids can result in short-circuiting and rust.
17) Do not remove the battery label
Do not remove or damage the battery label.
18) Use batteries within the recommended period
Batteries used within the recommended period will deliver the performance prescribed by JIS. Purchasing spare batteries for later use is acceptable if they are used within the recommended period.
19) Beware of fake and modified batteries
Batteries with no manufacturer or distributor names displayed or with no warning labels may be fake or modified batteries. Fake and modified batteries may have damaged or no safety mechanisms that prevent accidents. This is dangerous and may result in explosion or fire. Be careful not to purchase these batteries.
20) Inserting/removing battery into/from a device
Insert/remove a battery into/from a device according to the instructions in the device’s user’s manual and never use excessive force. After inserting the battery, check the behavior of the device, and in case of unstable behavior remove the battery and inspect the device.
