Camelion Lithium button cell CR1220 - 3V (blister pack of 5 / CAMCR1220B5)

The Camelion CR1220 (CAMCR1220B5) is a high-quality 3-volt lithium button cell that is known for its reliable energy delivery and long shelf life. The abbreviation "B5" in the article number typically stands for the packaging unit as a pack of 5 blister (tear-strip), making it ideal for storage or use in devices that require multiple cells.

This battery of size CR1220 (12.5 mm diameter / 2.0 mm height) offers high energy density in the smallest of spaces. It is the standard power source for a variety of small electronic devices in the home, office and medical field. Thanks to stable lithium technology (Li-MnO2) it delivers a constant 3 volts and is extremely temperature stable.

Highlights at a Glance

• Long shelf life: Camelion lithium button cells have a very low self-discharge rate (approx. 1-2% per year). They are storable for up to 10 years without significant loss of performance.
• High energy density: Despite their small size, the cell supplies a constant voltage of 3.0 Volt and a capacity of approx. 35 - 40 mAh.
• Wide temperature range: Can be used from -20°C to +60°C, making it ideal for car keys (winter cold) or outdoor sensors.
• Leak-proof: The robust housing construction prevents electrolyte leakage and protects your valuable small devices from corrosion.
• Environmentally friendly: Free from mercury (0% Hg) and cadmium (0% Cd).

Fields of Application

The CR1220 is a specific size that is often not found on supermarket shelves, but is needed in many devices:

• Watches: Wristwatches (digital/analogue) and small travel alarm clocks.
• Car keys: Remote controls for central locking (often for older Japanese or American models).
• Computer: As a CMOS buffer battery (BIOS) in laptops and netbooks (where the larger CR2032 does not fit).
• Medical technology: Blood glucose meters, digital clinical thermometers.
• Toys: Tamagotchis, small LED lights, calculators.
• Photo: Camera date backs.

Assembly & Safety Instructions

• Observe polarity: The flat side with the inscription ("Camelion CR1220 3V") is the positive terminal (+). The underside is the negative terminal. Always insert the battery the correct way round.
• Do not grip with metal tweezers: Do not touch both flat sides of the button cell at once with metal tweezers when replacing. This causes a short circuit that can discharge the battery in seconds. Use plastic tweezers or hold it only at the edge.
• Warning against swallowing: Button cells are life-threatening for young children! Keep out of reach. If swallowed, call emergency services immediately (danger of caustic burns).
• Disposal: Lithium batteries do not belong in household waste. Take empty cells to the green collection boxes in stores or the recycling centre.

FAQs about the Camelion CR1220

Is CR1220 the same as CR2032?

No. The numbers indicate the size:

• CR1220: 12 mm wide, 2.0 mm high.
• CR2032: 20 mm wide, 3.2 mm high (much larger). They do not physically fit in each other's compartments.

Can I use a CR1216 or CR1225?

• CR1216: Has the same diameter (12mm), but is thinner (1.6mm). It often has loose contact.
• CR1225: Is thicker (2.5mm). It usually doesn't fit in the slot or presses too hard on the contacts. Always use exactly the type CR1220.
