CR2016 is ideal for compact gadgets like wristwatches, calculators, remote controls, key fobs, and children’s toys. Beyond traditional electronics, it serves a crucial role in medical equipment such as portable thermometers and glucose monitors, as well as in personal digital assistants (PDAs), where data retention is maintained even during power loss.
Features:
As can be seen, CR2025 vs CR2016 have many things in common, which makes them quite hard to distinguish. Here are some similarities you should know:
CR2016 and CR2025 batteries follow the same naming convention, which is "CR" standing for lithium manganese dioxide, the chemical makeup of both batteries. And the numbers following indicate lithium coin cell battery sizes. So, you can understand that “20” refers to a 20 mm diameter, while the last two digits show the thickness, 1.6 mm for the CR2016 and 2.5 mm for the CR2025.
CR2025 vs CR2016 voltage has a nominal voltage of 3 volts, making them suitable for devices that need a steady 3V power supply. Typical applications are led lights remotes, watches, key fobs, calculators, digital thermometers, fitness trackers, and computer motherboards for CMOS memory. They are also ideal for powering artistic and handcrafted designs, such as decorative resin lights, where space is limited and low power consumption is required.
Both CR2025 vs CR2016 have the same 20 mm diameter, which affects how long each battery lasts and how they fit in certain devices.
Both CR2025 and CR2016 batteries are non-rechargeable lithium coin cells, designed for single-use only. Using them in a charger or attempting to recharge them can be dangerous and may damage the battery or the device.
Both batteries share the same lithium manganese dioxide (Li/MnO2) chemistry, giving them similar performance and stability. Compared to alkaline batteries such as AA and AAA (1.5V), Li/MnO₂ batteries provide a higher energy density, a longer shelf life, and a stable 3.0V output, making them ideal for compact and high-performance devices.
Despite appearing similar, there are 8 key differences between CR2025 and CR2016 that can impact how well they function in specific devices.
The CR2025 battery is thicker at 2.5 mm and is suitable for devices that have room for a larger battery. In contrast, the CR2016 is thinner at 1.6 mm, making it ideal for devices with smaller or tighter battery slots. It's important to check that your device’s battery compartment can fit this thickness.
The CR2025 battery weighs approximately 2.6 grams (0.08 oz.), making it slightly heavier than the CR2016, which weighs around 1.9 grams (0.07 oz.). This difference in weight is primarily due to the CR2025's greater thickness and higher energy capacity. While the weight difference is minimal, it can be a factor in ultra-light or size-sensitive electronic devices.
The CR2025 has a capacity of about 170mAh, meaning it can deliver more energy and last longer than the thinner CR2016, which typically holds around 100mAh. As a result, devices using CR2025 batteries may run longer compared to those powered by CR2016 batteries.
Because CR2025 batteries offer a higher energy capacity than CR2016 batteries, they are generally slightly more expensive. However, when deciding which battery provides better value, it’s important to consider how much power your device needs and how long the battery is expected to last. Choosing the right battery depends not just on price, but on how well it meets the performance and lifespan needs of your specific device.
The CR2025 battery delivers a longer usage time thanks to its higher capacity, lasting around 33 hours in a device that draws 5mA of current. In comparison, the CR2016 battery has a shorter lifespan, running for about 18 hours under the same power consumption. This difference makes the CR2025 more suitable for devices that require longer continuous operation.
The CR2025 battery is widely used in compact electronic devices due to its reliable 3V power output and long battery life. It is commonly found in car remote keys, providing consistent energy for locking and unlocking functions.
