RAYOVAC CR2032 coin cell batteries are 3V lithium button cells supplied in a pack of six, designed for reliable power in small electronic devices. These cells provide a stable nominal voltage suitable for low-drain and intermittent-use applications such as watches, calculators, key fobs, and motherboard CMOS memory. The compact, flat design and long shelf life make them convenient spares or replacements for a wide range of consumer and light industrial devices.
Advantages
These CR2032 batteries deliver a consistent 3V output with low self-discharge, ensuring stored devices retain power over long periods. Supplied as a pack of six, they offer convenient multi-device replacement or spare inventory. The lithium chemistry provides good performance at a range of ambient temperatures and a long shelf life compared with alkaline alternatives, while the standardized coin cell form factor fits common battery compartments.

How to use
Insert each CR2032 coin cell into the device battery compartment observing the correct polarity, usually marked with a + sign on the positive side. For devices with a battery holder, press the cell gently into place to ensure a secure contact. Replace cells one at a time to avoid loss of device settings when possible, and dispose of used lithium cells in accordance with local battery recycling regulations. Avoid short-circuiting the terminals and keep cells away from children and pets.
Usage recommendations
Store unused cells in a cool, dry place away from direct sunlight. For devices that provide low-battery indication, replace cells promptly to maintain device accuracy and to prevent data loss in memory-backed electronics. Do not attempt to recharge primary lithium coin cells; use only as single-use replacements.
