CR927 is used in hand watches mainly. It is hard to find a replacement between these models we explained already. this is a lithium battery. The handbook is wrong! The replacement for the National GR927 is the 399 silver oxide battery and not The CR2032 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches and medical devices. The cell battery chart explains how the three components of a cell battery interact to create an electric current. It shows that the anode is the negative electrode, while the cathode is the positive electrode. The electrolyte connects the two electrodes and allows current to flow between them. The chart also shows that the current is created when the charge of the anode is lower than the charge of the cathode. Button cell battery chart

the CR927 3V lithium battery. This mistake in the handbook appears across several different models of Casio solar calculators. Microbattery.com has been selling batteries online for over 25 Years and has one of the widest variety of batteries available, including all types of the CR2032 battery, from a variety of world-renowned manufacturers. For all your battery needs, please consider Microbattery.com and let them be your battery expert! If you are replacing a National GR927 battery in a Casio calculator please note that your calculator handbook is likely to say that Mercury watch batteries are no longer manufactured so your only alternative is to use a silver oxide watch battery of the same size. You should Use these data to compare each battery model with corresponding product numbers from various manufacturers. These battery comparison charts give you all the necessary data making it easy to choose an appropriate battery. Coin batteries are much alike, but there are differences between each model. After reading this article, you’ll be able to find equivalent batteries in size, voltage, capacity, and chemistry. Furthermore, you’ll learn all the differences between similar makes.

For further information about watch batteries; their chemistry, numbering, watch battery prefixes and Yes, CR2032 and CR2025 batteries are interchangeable. However, the CR2032 has a higher capacity than the CR2025, so it is better for applications that require more power. Additionally, the CR2032 has a longer shelf life than the CR2025, so it will last longer before needing to be replaced. Few words to end As said before, many of these button-cell batteries are interchangeable. You need to look for a battery that is close to the original – in size and nominal capacity. Furthermore, in many cases, it all depends on how the battery case is designed. Sometimes you can’t install a battery other than the original size.

MicroBattery Pro-Tip (Understanding Lithium Coin Batteries): Lithium coin cell batteries are usually designated with a CR followed by a set of numbers. The C in CR lets you know the battery uses a lithium chemistry. The R lets you know that the battery is round in shape. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. So by following this, you can easily see that a CR2032 battery is a (C) lithium chemistry battery with a (R) round shape that has a diameter of (20) 20 millimeters and a height of (32) 3.2 millimeters. This applies to the majority of coin and button cell batteries but note there are some exceptions, like the CR2 or CR123A batteries which are considered lithium cylindrical batteries. Button cell battery CR927 has significantly different measures than other batteries in this button cell battery dimension chart.
