When your car key stops responding or the remote control fails, the cause is often a dead battery. The CR2016 battery is used in many of these small, everyday electronic devices. This guide will help you find the right replacement battery and presents a selection of reliable models. Our goal is to provide you with a clear basis for your decision, based on objective product features.
Choosing the right coin cell battery depends on several factors. To ensure your device functions perfectly again, consider the following points.
The most important detail is the model designation CR2016. This standardized identifier, according to the IEC standard, provides information about the cell's chemical composition, shape, and dimensions:
Some manufacturers use alternative designations like DL2016. Always check the label on your old battery or in the device's manual to ensure compatibility. Although batteries like the CR2025 or CR2032 have the same diameter, they are not interchangeable due to their different heights.
A CR2016 lithium battery delivers a stable voltage of 3V, making it suitable for a wide variety of devices. However, requirements differ depending on the application. A battery for a car key or medical device needs a consistently high and long-lasting power output. In contrast, a battery for a remote control or a kitchen scale has a lower, often intermittent power demand. Pay attention to the manufacturer's specifications for longevity and suitability for high- or low-drain devices.
Safety is a crucial factor, especially in households with children. Leading manufacturers like Duracell CR2016 and Varta CR2016 offer child-resistant packaging that can only be opened with scissors. Some models are also coated with a bitter substance (Bitrex) to prevent accidental ingestion. A long shelf life of up to ten years also ensures that you always have a working replacement battery on hand.
Based on the criteria mentioned, we have compiled a selection of CR2016 batteries that are suited for different users due to their specific properties.
Why It Stands Out: This model from Duracell places a special focus on safety. The combination of child-resistant double-blister packaging and a coating of the bitter substance Bitrex on both sides minimizes risks in households with young children. According to the manufacturer, a shelf life of 10 years is guaranteed, making it a great choice for stocking up.
Pros:
Best For: Users for whom child safety is a top priority and who want to stock up on a long-lasting battery for occasional replacement in devices like car keys, scales, or fitness trackers.
Why It Stands Out: The 5-pack from Varta offers good value for money for users with multiple devices or higher consumption. The batteries are designed for a wide range of electronics, from remote controls and toys to medical devices. Varta also uses child-resistant packaging to ensure household safety.
Pros:
Best For: Users who regularly need CR2016 coin cell batteries and want to stock up for various devices like remote controls, scales, watches, and calculators.
Why It Stands Out: Energizer is known for reliable power solutions. This CR2016 lithium battery 4-pack is specifically designed for the demands of devices like key fobs and garage door openers, which require stable voltage and longevity. With a capacity of 90 mAh per cell, it provides a steady power supply for demanding small devices.
Pros:
Best For: Owners of car keys, garage door openers, and other devices where reliable and long-lasting performance is critical.

All three battery types have the same 20 mm diameter and a voltage of 3V. The key difference is their height:
The shelf life of an unused CR2016 lithium battery is very long. Many manufacturers state a shelf life of up to 10 years when the battery is stored in a cool, dry place in its original packaging. The actual lifespan in a device depends heavily on its energy consumption and can range from a few months to several years.
The CR2016 coin cell battery is a widespread power source for a variety of small electronic devices. The most common applications include:
