![]() The CR2032 can provide 10 hours of use, while you only get about six hours from the CR2016, depending on the power you're using, of course.ĭue to their equivalent voltage, there are several cases where CR2016 and CR2032 can be interchanged. CR 2032 has a capacity of 240 mAh, while CR2016 has a capacity of just 90 mAh. However, it is important to remember that there are variations in ability. They're both 3-volt versions, and none of them is rechargeable. The last two numbers on any CR battery will tell you the thickness in millimeters.ĬR2016 and CR2032 may vary in thickness, but they are identical in several ways. CR2032, the CR2016 is 1.6 millimeters thick and the CR2032 is 3.2 millimeters thick. These four numbers refer to the thickness of the battery itself. ![]() However, CR batteries are more affordable, making them popular with devices such as smoke detectors, bathroom scales, wristwatches and calculators.Įach CR battery has four numbers, unique to that battery. For this reason, BR batteries tend to be used for electronics, such as cellphones and laptops, where life is important. The initial discharge of CR batteries is higher than the initial discharge of BR batteries, but should be phased out as the battery ages. BR batteries are known to operate at high power from start to finish, while also being able to withstand hot temperatures.Īnother type of button battery, the CR battery, is a manganese lithium dioxide battery. The BR-type is the standard for small lithium-ion batteries, casually referred to as "button batteries" or "coin batteries" because of their small, round size. The most common type of lithium-ion battery is a polycarbon monofluoride battery called BR. So, in order to clarify the difference between CR2032 battery and CR2016 battery, and not to be confused by the similar appearance when buying the battery, take a look at the content: If you make a mistake by accident, you will have to place another order to buy it lol. ![]() Therefore, we cannot simply use the two batteries. Since they all look the same, can they be used universally?Īlthough CR2032 battery and CR2016 battery share similarities, there are actually DIFFERENCES in battery thickness and battery capacity. My usage is dailly, with more than 10.Sometimes, CR2032 batteries and CR2016 batteries that are round, flat, and look like small silver buttons seem to look the same. So, without getting a real "low battery" warning, the watch is actually semi-usable after just 1 year. As days go by, "R" mode gets almost daily activated when I press the light or try to connect via bluetooth. After one year+ (13 months) the watch started again exactly the same behavior. So, I replaced the battery (thinking it was outdated) in official CASIO service. In this mode a flashing R appears on screen and every function is temporarily disabled (timekeeping continues in the background and time hands / display restore correct time when power delivery becomes OK). These g-shock have a "power-saver" mode when they feel that power drain exceeds power output from the battery. I got it second hand and after some months (and without getting the battery-low warning) it became unstable when trying to connect via bluetooth, when pressing the buttons many times etc. I use a GBA-800 (with steps tracking) for the past 1,5 year.
