The CR2032 boasts a cell capacity of 220 mAh.The capacities of these batteries are as follows: The CR2016 is 20 mm in diameter with a 1.6 mm thickness.The CR2025 has a diameter of 20 mm and a 2.5 mm thickness.The CR2032 is therefore 20 mm in diameter and 3.2 mm thick.The batteries in our review actually have different thicknesses: The last two numbers show the thickness or depth of the battery cells. In our case, it is “20” for 20 mm diameters, as we already know. The first two numbers denote the diameter of the battery cells. The letter “R” indicates the physical shape of the battery, meaning it is round. The “C” letter represents the chemical composition of the battery to Lithium Manganese dioxide.
The IEC defines the letters for these batteries, and these three selected batteries actually contain Chromium. The word “CR” stands for Chromium in the world of science. Of course, the names distinguish the attributes of each of these batteries to better differentiate them to you and me. In fact, the International Electrotechnical Commission (IEC) has designated these combinations and letters to name these types and sizes of batteries. Let’s break down the labels and names of the CR2032, CR2025, and CR2016 types. These brands produce millions of CR2016, CR2025, and CR2032 batteries each year for the consumer market. The most popular brands of button cell batteries are Energizer, Panasonic, Duracell, Sony, BrighTown, Celewell, Amazon Basics, LiCB, and AmVolt. Coin cell batteries are not only found in devices such as wristwatches and calculators but also found in: car keys, garage remote controls, keyless entry systems, laser pens, fitness devices (such as heart rate monitors), medical devices (such as tensiometers and glucose monitors), countless varieties of children’s toys, board games, handheld gamepads, and even as memory back-ups for computer BIOS systems, and more. Manufacturers extensively research, develop, and produce their products to be used with a specific battery type and size to meet their exacting engineering demands. By opening the battery compartment, you’ll be able to replace the battery relatively easily. So, your watch or calculator is on the fritz. It also means that these batteries produce the same energy discharge rate. The CR2032, CR2025, and CR2016 provide 3 volts of energy through a circuit. What you can’t see, however, is that all three of these coin cell batteries generate the same voltage. The CR2032, CR2025, and CR2016 all have a diameter of 20 mm. If you stack them one on top of the other, you’ll notice that they all have the same diameter. They also carry the same internal components: Manganese dioxide cathodes and lithium anodes. That’s because the CR2032, CR2025, and CR2016 batteries share a great deal of similarities.įirst, these three batteries share the same chemical composition of Lithium-Manganese dioxide (LiMn02). While the names of these batteries mean they’re different you’ll be hard-pressed to distinguish between them. Despite being so small compared to AAA, AA, D, or other sized batteries, these coin ones also have lithium cells – just like your smartphone.
CR2016 for BIOSĬommonly referred to as button or coin cell batteries, these tiny batteries power more gadgets and devices than you could imagine.
