Coin cell battery No name CR2032 — 3V lithium, pack of 4

Coin cell battery No name CR2032 — 3V lithium, pack of 4 contains four standard CR2032 lithium button cells designed for use in small electronic devices. Each cell delivers a nominal voltage of 3V and a compact, flat design that fits into standard CR2032 holders. These batteries are intended to provide stable voltage over their service life and retain charge during storage, making them suitable for low-drain and intermittent-use applications.

Advantages

The CR2032 cells offer long shelf life and reliable voltage stability under typical operating conditions. Their standardized dimensions ensure broad compatibility with devices designed for CR2032 cells. Supplied as a pack of four, this set provides immediate replacement options and reduces the need for frequent purchases. The lithium chemistry provides good energy density for the cell size and maintains capacity at low temperatures better than alkaline alternatives.

Suitable for

• Wristwatches and wearable devices
• Calculators and small electronic instruments
• Key fob remotes and car immobiliser devices
• Fitness trackers and health wearables
• Motherboard CMOS memory and RTC backup
• Small medical devices such as glucose monitors and thermometers

Key specifications

• Cell type: lithium button cell
• Nominal voltage: 3 V
• Format: CR2032 standard dimensions (coin cell)
• Quantity: 4 cells per pack
• Typical usage: low-drain and intermittent-load devices
• Storage characteristics: long shelf life when stored in original packaging

How to use

Before installation, confirm the device requires a CR2032 3V battery and observe polarity markings on the device and the battery. Power down the device or remove access to live circuits where applicable. Insert the cell into the compartment with the correct orientation — the flat positive side (+) typically faces up — and secure the cover or holder according to the device instructions. After replacement, verify device operation and dispose of the spent batteries according to local regulations for lithium batteries.

Usage recommendations

Store unused cells in a cool, dry place and keep them in original packaging until needed to preserve shelf life. Avoid exposing the batteries to high temperatures, open flames, or short-circuit conditions. Do not attempt to recharge or disassemble the cells. For devices with continuous memory backup, replace the battery proactively to prevent data loss and consult device documentation for recommended replacement intervals.
