This guide explores everything you need to know about the CR2016 battery, including its specifications, applications, advantages, and why GMCELL is a top choice for wholesale buyers.
What Is a CR2016 Button Cell Battery?
The CR2016 is a 3-volt lithium manganese dioxide (Li-MnO₂) coin cell battery, designed for compact, low-power devices. Its name follows a standard coding system:
●”CR” – Indicates lithium chemistry with manganese dioxide.
●”20″ – Refers to the diameter (20mm).
●”16″ – Denotes the thickness (1.6mm).
Key Specifications:
●Nominal Voltage: 3V
●Capacity: ~90mAh (varies by manufacturer)
●Operating Temperature: -30?C to +60?C
●Shelf Life: Up to 10 years (low self-discharge rate)
Chemistry: Non-rechargeable (primary battery)
These batteries are prized for their stable voltage output, long lifespan, and leak-resistant design, making them ideal for critical applications where reliability matters.

CR2016 vs. Similar Button Cell Batteries
While the CR2016 is widely used, it’s often compared to other button cells like CR2025 and CR2032. Here’s how they differ:
FeatureCR2016CR2025CR2032
Thickness1.6mm2.5mm3.2mm
Capacity~90mAh~160mAh~220mAh
Voltage3V3V3V
Common UsesSmall devices (watches, key fobs)Slightly longer-lasting devicesHigh-drain devices (some fitness trackers, car remotes)
Key Takeaway:
●CR2016 is best for ultra-thin devices where space is limited.
●CR2025 & CR2032 offer higher capacity but are thicker.
How to Maximize CR2016 Battery Life
To ensure optimal performance and longevity:
1. Proper Storage
●Keep batteries in a cool, dry place (avoid humidity).
●Store at room temperature (extreme heat/cold reduces lifespan).
2. Safe Handling
●Avoid short-circuiting – Keep away from metal objects.
●Do not attempt to recharge – CR2016 is a non-rechargeable battery.
3. Correct Installation
●Ensure proper polarity (+/- alignment) when inserting into devices.
●Clean battery contacts periodically to prevent corrosion.
4. Responsible Disposal
●Recycle properly – Many electronics stores accept used button cells.
●Never dispose of in fire or general waste (lithium batteries can be hazardous).
Frequently Asked Questions (FAQs)
Q1: Can I replace a CR2016 with a CR2032?
●Not recommended – The CR2032 is thicker and may not fit. However, some devices support both (check manufacturer specs).
Q2: How long does a CR2016 battery last?
●Varies by usage – In low-drain devices (e.g., watches), it can last 2-5 years. In high-drain devices, it may last months.
Q3: Are GMCELL CR2016 batteries mercury-free?
●Yes – GMCELL complies with RoHS standards, meaning no hazardous materials like mercury or cadmium.
