VARTA rechargeable nickel metal hydride button cells

Fresh air. Seek for medical assistance.

Remove solid particles immediately. Flush affected areas with plenty of water (at least 15 min). Remove contaminated cloth immediately. Seek for medical assistance.

Flush the eye gently with plenty of water (at least 15 min). Seek for medical assistance.

After ingestion of battery components: Avoid vomiting. Seek for medical assistance. No trials for neutralization. After ingestion of battery: In the event of battery ingestion, seek immediate medical attention at a hospital emergency room. Do not let the person who ingested the battery eat or drink until an X-ray can determine if a battery is present. If you still have the battery packaging or the device containing the battery take this with you to help the physician identify the battery type and chemistry.

Use foam, dry powder or dry sand, as appropriate

Water and carbon dioxide (CO₂) are only applicable for incipient fire.

Under fire conditions, the electrode materials can form carcinogenic nickel and cobalt oxides.

In the event of cell rupture, prevent skin contact and collect all released material in a plastic lined container.

If cell casing is dismantled, small amounts of electrolyte may leak. Pack the cell or its remains including ingredients as described above.

Avoid leached substances to get into the earth, canalization or waters.

Then clean with water.

Materials: water

Always follow the warning information on the batteries and in the manuals of devices. Only use the recommended battery types. Keep small cells and batteries which are considered swallowable out of the reach of children. For devices to be used by children, the battery casing should be protected against unauthorized access. Unpacked batteries shall not lie about in bulk. In case of battery change always replace all batteries by new ones of identical type and brand. Do not swallow batteries. Swallowing may lead to burns, perforation of soft tissue, and death. Severe burns can occur within 2 h of ingestion. In case of ingestion of a cell or battery, seek medical assistance promptly. Do not throw batteries into water. Do not throw batteries into fire. Avoid deep discharge. Do not short-circuit batteries. Use recommended charging time and current. Do not open or disassemble batteries. Do not drop batteries. Batteries that have been dropped by accident shall be disposed off accordingly.

Storage preferably at room temperature (approx. 20°C). Avoid large temperature changes. Do not store close to heating devices. Avoid direct sunlight. At higher temperature the electrical performance may be reduced. Storage of unpacked batteries can cause short circuit and heat generation.

A fire alarm is recommended. For automatic fire extinction consider section 5.

When heated above 150 °C the risk of rupture occurs. Due to special safety construction, rupture implies controlled release of pressure without ignition.

heated above 150 °C

In the USA, safe for disposal in the normal municipal waste stream. In the European Union, follow Regulation (EU) 2023/1542.

Special Provision 963: nickel-metal hydride cells or batteries shall be securely packed and protected from short circuit.

Special Provision A199: Nickel-metal hydride batteries or nickel-metal hydride battery-powered devices, equipment or vehicles having the potential of a dangerous evolution of heat are not subject to these Regulations provided they are prepared for transport so as to prevent: (a) a short circuit; and (b) unintentional activation.
