CR2016 is the smaller one, thick only 1.6mm, providing only 90mAh. Differences between these models are in size and nominal capacity. They all have 3V output and look the same at first sight. What is the difference between CR2016 vs CR2025 vs CR2032 CMOS watch battery specsĪs you can see, battery models (CR2032, CR2025, or CR2016) are representing the physical size for each one.Įach model has 3V, but sizes vary. Take a look at these models of laptop CMOS (BIOS) coin batteries. If you are looking for laptop CMOS battery Finally, if you manage to replace the battery successfully (with CR2025 or CR2016), make sure to buy an appropriate model soon (CR2032) and replace that battery once again. This should work, but there is no guarantee. Only if you don’t have a spare battery (CR2032), you can try to place a CMOS battery with CR2025 or CR2016. To be sure, if changing the CMOS battery, try to buy an appropriate model and replace the old battery with a new one.

This battery may be sufficient to keep saved settings inside your PC BIOS, but sure it will trigger a warning message on low voltage very soon. CR2016 is even thinner than CR2025 and less powerful. CR2016 have less power (nominal capacity) and it is a bit thinner (1.6mm), CR2032 is 3.2mm thick. This means that CMOS can still give an error message (warning) to replace the battery with a new one.ĬR2032 vs CR2016: Both models have 20mm in diameter. Note: CR2032 nominal capacity is 220mAh, compared to CR2016 which has only 90mAh.
CR2016 has only 45-50% nominal capacity compared to CR2032 batteries. The same diameter size sure is good, but the nominal capacity difference is not something to rely on. Using CR2016 as a replacement CR2032 battery could be a problem. Try booting your PC and see if you get rid of error messages on boot. Keep in mind that you need to prepare CMOS battery housing, and avoid loose contact.

This shouldn’t be a problem if you are using a new battery with full capacity.ĬR2032 vs CR2025: Both models have 20mm in diameter, while 25 has less power (nominal capacity) and it is a bit thinner (2.5mm), CR2032 is 3.2mm thick. Replacing the CMOS battery with this one means you have used a battery with a 75% nominal capacity of the original one. However, if needed, you can try placing CR2025 instead.ĬR2025 is a bit smaller in size (same diameter), with a less nominal capacity value. CR2032 is the strongest, and the biggest one. Two battery models are different in size and nominal capacity. It depends on which CR battery model you are using, the contact terminal needs to be appropriately prepared. To avoid loose contact, before placing a new battery, just do a slight pressure on the positive terminal. CR2025 and CR2016 batteries are a bit thinner (CR2025 2.5mm and CR2016 1.6mm) which means they may have loose contact in the battery case. Battery size and nominal capacity are things we need to care about. If you are stuck with opened computer housing and don’t have exactly the battery model you need, try to use one of the battery types which is close enough.Ĭoin battery CR2032 has 220mAh (nominal capacity), 20mm in diameter, with 3V output. However, sometimes we start doing replacements without preparation. While approaching this problem, we all want to replace the current battery with an appropriate one. Changing BIOS battery, which one to choose?
Fortunately, the BIOS battery is the biggest one and we can use another CR model if necessary. If you look at the table above, the diameter is the same for all 3 models, while the high size is a bit different for each model. You need to prepare a new battery, take out the old one, and firmly place a new CR2032 battery. Replacing batteries on the motherboard is quite easy. Still, sometimes we need to replace the battery from the motherboard, to avoid seeing BIOS warnings while the system is booting. A small battery can operate for a long time in that kind of environment. This battery’s main purpose is to keep BIOS settings, even if the computer is unplugged. In a modern computer most likely you will find the CR2032 coin battery model. Specification table for coin batteries CR2032, CR2025 and CR2016 Model Not only CR2032, CR2025, CR2016 are different in size, they do have different specifications also. However, there are some crucial differences. Small coin shape batteries are hard to distinguish on a first look. CR2025 and CR2016 models are used inside remotes and mostly in modern quartz watches.ĬR2032 battery is used in CMOS “Complementary Metal Oxide Semiconductor” technology of production integrated circuits. Small BIOS battery is also known as a Button cell, CMOS battery, coin battery, etc… Most modern computers are using the CR2032 battery model on their motherboards.
