1. Battery identification

2. Manufacturer and regulatory information

VARTA Microbattery GmbH’s manufacturer documentation declares that the CR2032 battery model complies with the applicable substance-restriction requirements of Article 6 of Regulation (EU) 2023/1542 concerning batteries and waste batteries.

According to the manufacturer’s documentation, the battery complies with the applicable limits for mercury, cadmium and lead. The manufacturer’s material declaration also identifies substances subject to REACH disclosure requirements.

The declarations linked below apply to the manufacturer’s battery model or product family. They should not be interpreted as batch-specific manufacturing or traceability records.

3. Safety instructions

Observe the following precautions:

• Do not recharge the battery.
• Do not short-circuit the battery.
• Do not open, dismantle, crush or deform the battery.
• Do not expose the battery to fire or excessive heat.
• Do not immerse the battery in water.
• Do not mix used and new batteries.
• Replace the battery only with the specified type.
• Keep the battery away from children and pets.

4. Handling and storage

• Store batteries in a cool, dry place.
• Avoid contact with conductive materials that could cause short circuits.
• Do not use batteries that show signs of damage, leakage or deformation.
• Do not attempt to dismantle or repair a battery.
• Protect batteries against excessive heat and mechanical damage.

5. Fire safety

Lithium button cells may release hazardous substances if overheated, damaged or exposed to fire.

According to the manufacturer’s Safety Data Sheet, suitable extinguishing agents include metal-fire extinguishing powder, rock salt and dry sand. Carbon dioxide (CO₂) is not suitable according to the manufacturer’s Safety Data Sheet.

If water is the only available extinguishing medium, the manufacturer specifies using large quantities. Firefighting involving batteries should be carried out by trained personnel using appropriate protective equipment and self-contained breathing apparatus.

6. Disposal and recycling

Batteries must not be disposed of with unsorted household waste. They must be collected separately and delivered to an appropriate battery collection or recycling point.

• Do not dispose of batteries in household waste.
• Do not incinerate or dismantle used batteries.
• Prevent short circuits during storage and transport of used batteries.
• Keep used batteries away from children.
• Use designated battery collection points for disposal.

Separate collection enables the recovery of valuable materials and helps prevent environmental pollution. For further information, consult your local waste-management authority or battery-collection service.
