Coin cell battery Varta CR2016 3V lithium — 2 pcs

Varta CR2016 is a 3V lithium coin cell battery supplied as a pack of two. The battery is sized for devices that accept the CR2016 format and provides a stable nominal voltage suited to low-drain electronics such as calculators, key fobs, small watches, certain medical instruments and motherboard CMOS memory. The cell features long shelf life characteristics of lithium chemistry and is intended for applications requiring compact, reliable backup or primary power at low current draw.

Advantages

The Varta CR2016 delivers a consistent 3V output and stable performance under low-drain conditions, with minimal self-discharge for extended shelf life. Its compact coin form factor enables installation in tight device compartments, while the metal casing ensures mechanical durability and safe contact with battery holders. Supplied as a two-piece pack, it allows immediate replacement of depleted cells or keeping a spare on hand.

Suitable for

• Calculators and small electronic toys
• Remote controls and key fobs
• Wristwatches and small timekeeping devices
• Motherboard CMOS/BIOS memory backup
• Low-power medical devices and small sensors

Key specifications

• Chemistry: Lithium manganese dioxide (typical for 3V coin cells)
• Nominal voltage: 3 V
• Cell size: CR2016 coin cell dimensions (20 mm diameter, 1.6 mm height)
• Pack quantity: 2 batteries per pack
• Typical application: Low-drain devices and memory backup

How to use

Before installing, verify the device accepts CR2016 size and observe correct polarity when inserting the cell into the holder. Replace depleted cells with identical type and dispose of used batteries according to local regulations for lithium cells. Avoid short-circuiting the terminals and keep batteries away from extreme heat sources. For devices with multiple cells or battery compartments, follow the manufacturer’s instructions to ensure proper seating and contact.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and metallic objects. Use within the manufacturer’s recommended shelf life and replace cells in timekeeping or memory-backup applications to prevent data loss.
