Duracell CR2016 3V Lithium Coin Batteries 2 Pack

Usage

The Duracell CR2016 button cell batteries are designed to power small electronic devices such as watches, medical instruments, key fobs, fitness trackers, remote controls, and wireless sensors where reliable and compact energy is essential.

Advantages

• High-purity lithium chemistry ensures stable 3V output for device reliability
• Innovative bitter coating and secure packaging help discourage accidental swallowing by children
• Low self-discharge rate—less than 1% loss per year when stored at room temperature—supports long shelf life up to 10 years
• Wide operating temperature range from -20°C to +60°C provides versatility in various environments
• Slim form factor (20 mm diameter × 1.6 mm thick) fits compact devices but has lower capacity compared to thicker cells like the CR2032

Specifications

• Chemistry: Lithium Manganese Dioxide (Li/MnO₂) with high-purity lithium construction and child-resistant retail blister packaging
• Certified for safety (IEC 60086-4), transport (UN38.3), REACH compliance; produced in ISO9001-certified facilities; features triple corrosion protection technology
• Nominal voltage: 3V; typical capacity: about 90–110 mAh*; dimensions: diameter of 20 mm and thickness of only 1.6 mm; typical weight approx. 1.7–2 g
• Bitter coating on battery surface deters ingestion; packaging nearly impossible to open by hand without tools; guaranteed up to ten years in storage

How it works

The battery provides a continuous DC voltage output through a chemical reaction between lithium metal and manganese dioxide inside its sealed cell. Simply insert the coin cell into your compatible device’s battery compartment with correct polarity for dependable power until replacement is needed.
