The proper and safe handling of nickel-metal hydride and nickel-cadmium 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 the battery

Do not connect the positive and negative terminals of a battery with a metallic object. Do not carry or store a battery together with necklaces, hair pins, coins, keys, or other metallic items. Metallic objects may short-circuit the positive and negative terminals of the battery, resulting in the flow of a large electrical current that may cause heat generation, explosion or fire, or generate heat in the metallic object.

3) If something unusual is noticed, stop using the battery

If the battery leaks, gives off an odor, is discolored, is deformed, or reacts in anyway unusual during use, do not use it again. Continuing to use such batteries may result in overheating or explosion.

4) Be sure to recharge the battery with the specified battery charger

When recharging the battery, make sure that the positive and negative terminals are correctly connected, and use the specified battery charger in the proper manner. Using a battery charger other than specified one may result in overheating, leakage or explosion.

5) Do not use the battery together with different types and/or brands or fully charged and different capacity batteries

The use of a mixture of different types and/or brands, or fully charged and different capacity batteries even of the same brands or types, may result in overheating, leakage, or explosion. When replacing batteries, use fully charged batteries of the same type and brand.

6) Keep batteries out of reach of children

Keep batteries out of reach of children as they may accidentally swallow them. In the event that children swallow a battery, immediately consult a doctor. In addition, do not allow children to remove batteries from inside devices. Do not allow animals to play with batteries.

7) Always turn off the switch after use of devices

The cause of leakage in many cases is the failure to turn off the device. Certainly turn off devices when they are no longer in use.

8) 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, certainly remove the batteries when the device will not be used for a long time. Put the removed battery into a case individually and be careful not to short-circuit.

9) 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.

10) 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.

11) Do not give a strong impact to the battery

Do not give a strong impact to the battery by dropping batteries from high places or throwing them. Doing so may deform the battery and create an internal short-circuit, resulting in leakage, overheating or explosion.

12) Do not get batteries wet

Getting a battery wet with water, salt water, juice or other liquids can result in short-circuiting and rust.

13) Do not throw a battery into a fire

Do not throw a battery into a fire or heat it. This is dangerous and could result in heat generation, explosion, or fire.

14) Do not remove the battery label

Do not remove or damage the battery label. Removing or damaging the label makes the battery easier to short-circuit, and may result in leakage, overheating or explosion.

15) 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. Modifying the battery may damage the protection mechanism resulting in explosion, overheating or fire.

16) Do not directly solder batteries

Do not apply solder directly to the terminals of a battery. The heat will melt the insulator, damaging the gas exhaust vent and the protection mechanism, which lead to overheating, explosion or fire.

17) Beware of fake and modified batteries

Batteries that have no manufacturer or distributor names or warning labels displayed may be fake or modified ones. Fake and modified batteries may have damaged or missing safety mechanisms that are designed to prevent accidents. This is dangerous because it may result in explosion or fire. Be careful when purchasing such batteries.
