Product Description

The Duracell CR2032 is engineered to provide reliable power for up to 10 years in storage, making it an ideal choice for emergency backups and devices that are used infrequently. One of its standout features is the Bitrex coated "Baby Secure" ring—a bitter-tasting layer on the back of the cell designed to discourage accidental swallowing by children. The high energy density of lithium chemistry ensures that devices like digital scales and calculators run longer between battery changes.

Key Features

Child Safety Innovation: Features a bitter coating and double-blister tamper-proof packaging to help prevent accidental ingestion by toddlers.
Long Shelf Life: Duracell guarantees these batteries will stay powered for up to 10 years when stored correctly, perfect for stocking up.
High Energy Density: Provides a stable 3V output throughout most of its life cycle, ensuring consistent performance in precision electronics.
Leak-Resistant Casing: High-quality stainless steel construction prevents electrolyte leakage, protecting your expensive devices from corrosion.
Wide Temperature Range: Performs reliably in temperatures ranging from -20°C to +60°C, suitable for outdoor sensors or automotive remotes.

Technical Details

Self-Discharge Rate: Less than 1% per year.
Common Equivalents: DL2032, BR2032, KCR2032, LM2032.

Prototyping and Engineering Tips from Robogears

Identify the Size: The "2032" name tells you the dimensions: 20mm diameter and 3.2mm height. If your battery holder is thinner, you might need a CR2016 or CR2025; if it's thicker, a CR2032 will be loose.
Handling with Care: Avoid touching the flat surfaces of the battery with your bare fingers. Skin oils can create a high-resistance film that reduces the battery's effective life. Handle them by the edges or use plastic tweezers.
The "Plus" Side: The entire top and sides of the battery are the Positive (+) terminal, while the circular bottom face is the Negative (-) terminal. Ensure your holder’s spring contacts are clean and correctly oriented.
CMOS Battery Tip: If your PC or laptop keeps resetting its time and date every time you turn it off, it's a sign that the CR2032 on the motherboard has died and needs replacement.

Disclaimer

This is a non-rechargeable battery. Never attempt to charge a lithium coin cell, as it can leak or explode. Dispose of used lithium batteries at designated recycling centers.
