Introduction
Lithium batteries are everywhere in our daily lives—from watches and calculators to car remotes and medical devices. Among the many types of lithium batteries, the button cell is one of the most common. These tiny batteries are known for their compact size and long shelf life. This article will focus on one specific type: the CR2016 battery. This guide will help you understand everything you need about the CR2016 batteries, including its features, uses, and how to choose the right one.
The Overview of Button Cell Battery CR2016
The CR2016 battery is a small, flat button cell battery that belongs to the lithium coin battery family. It is known for its thin shape, reliable power, and long storage life. The name CR2016 gives us some information about the battery. The name "CR" comes from its chemical makeup, which stands for Lithium Manganese Dioxide (LiMnO2). The "2016" part shows its size: 20mm in diameter and 1.6mm thick.
Because of their small size and long shelf life, CR 2016 batteries are often used in devices that need little power but last a long time. They are very popular because of their stable 3V output and long-lasting performance. You can find them in devices like car key fobs, fitness trackers, digital thermometers, and more.
Understanding the technical specifications of a battery CR2016 is essential to ensure you choose the right power source for your device. Below is a table summarizing the key technical details of a standard CR2016 3v battery:

Key Features and Benefits of CR2016 3V Battery
CR2016 button cells are very popular in the small electronics world. They have some special features that make them ideal for many uses.
- Compact & Lightweight: The CR2016 coin battery is tiny and weighs very little. Their compact design allows them to fit into thin and sleek devices without making them bulky.
- High Energy Density: Even though small, CR2016 3 volt battery can hold a lot of energy, which means it lasts longer without needing to be changed often.
- Low Self-discharge Rate & Long Shelf Life: At room temperature (25°C), it loses only about 1% of its charge per year. That means it can sit in a drawer for over 5 years and still work when needed.
- Wide Operating Temperature Range: The lithium CR2016 battery works well in both cold and hot environments, from -30°C to 60°C, which makes it reliable in all seasons.
- Low Internal Resistance: This allows for more efficient energy use and better performance in devices that need quick bursts of power.
- No Memory Effect: Since it's not rechargeable, it doesn't have the memory issues that some other batteries do.
- Eco-friendly: CR2016 batteries are mercury-free and safer for the environment.
- Safe & Reliable: Designed not to catch fire, leak, or explode, the CR2016 button battery is made with safety in mind.
Common Uses for CR2016 3 Volt Battery
The battery 3v CR2016 is commonly used in many small devices because it provides steady voltage and fits into tight spaces. Here are five popular uses:
1. Wristwatches
Many analog and digital watches need small, lightweight batteries that can last long without replacement. The CR2016 lithium battery is a perfect match because of its slim size and stable 3V output. It fits easily inside watch cases and provides steady power for months or even years. Also, its low self-discharge rate means the watch keeps working even if not worn daily.
2. Car Key Fobs
Car key fobs rely on small, powerful batteries to send signals to lock or unlock vehicles. The 3v CR2016 battery is commonly used because it delivers reliable energy in a compact form. Its long shelf life and consistent performance make it perfect for remote car keys, which may sit unused for days but need instant power when pressed.
3. Digital Luggage Scales
Digital luggage scales need dependable batteries that won't die halfway through use. The CR 2016 battery provides enough energy for the scale's small digital display and sensors. Since people don't use luggage scales daily, the battery's long storage life and low drain make it very useful. It stays ready whenever needed, especially before flights or trips.
4. LED Lights (Mini or Clip-on)
Small LED lights like light strips, keychain flashlights, or clip-on book lamps often use CR 2016 batteries. These devices don't need much power but need stable and quick energy when turned on. The CR2016 button battery handles this well, providing bright, reliable light in a tiny package. Its low weight also keeps the lights easy to carry.
5. Laser Pointers
Laser pointers are another device for which CR2016 coin batteries are an excellent fit. They need a small power source that can provide quick bursts of energy. CR2016 batteries deliver just that, offering strong voltage output in a flat, compact design. Because of their balance of size and power, they are widely used in laser pointers for presentations or pet toys.
