CR-2032/VCN

What type of battery is this?

This is a non-rechargeable lithium coin cell designed for compact, low-drain electronic applications. The Panasonic CR-2032/VCN belongs to the CR family, which uses lithium manganese dioxide chemistry and is widely selected where stable 3 V output is required in a small format.

Is this a rechargeable battery?

No. This is a primary battery, which means it is intended for single-use operation until depleted. It should not be recharged.

What nominal voltage does it provide?

This battery provides a nominal voltage of 3 V, which is standard for CR-type lithium coin cells.

What size format does it use?

It uses the 2032 coin cell format, commonly understood as approximately 20 mm in diameter and 3.2 mm in thickness. This helps buyers match it to equipment designed around the same physical footprint.

What chemistry does this battery use?

It uses lithium manganese dioxide chemistry. In the Panasonic CR-2032/VCN, the main active materials include lithium at the negative electrode and manganese dioxide at the positive electrode.

What kinds of applications is this battery commonly used in?

This style of coin cell is commonly used for memory backup, real-time clock retention, small electronic instruments, meters, sensors and other compact devices that need dependable low-power operation over an extended period.

Can it replace other 2032-format coin cells?

It may be suitable as a replacement where the equipment requires a 3 V 2032-format lithium coin cell, but buyers should always confirm the required chemistry, dimensions, contact style and electrical characteristics against the equipment specification before installation.

Are there any important handling precautions?

Yes. This battery should not be recharged, crushed, incinerated or exposed to excessive heat. It should also be installed with the correct polarity and kept away from children, as coin cells can present a serious ingestion hazard.

How should this battery be stored?

It should be stored in a cool, dry environment and protected from short circuits, physical damage and high temperatures. Good storage practice helps preserve performance before use.

How should depleted batteries be disposed of?

Used batteries should be disposed of in accordance with local regulations for batteries and electronic waste. They should not be incinerated, and bulk quantities should be handled through appropriate disposal channels.

What materials are contained inside the cell?

According to Panasonic information for CR-type lithium batteries, the cell contains manganese dioxide, lithium and an electrolyte system based on organic solvents and lithium salt. These materials are enclosed within the sealed coin cell during normal use.

Why is this type of battery popular in compact electronics?

This type of battery is widely used because it combines a compact footprint with stable 3 V output and long service potential in low-drain applications. That makes it a practical choice where space is limited but reliable standby or backup power is still needed.
