The biggest distinction is the size. BR1220/CR1220 batteries have 12.5 x 2.0 mm physical dimensions, a lower capacity (35–40 mAh), and somewhat lower drain currents. BR1225/CR1225 batteries have 12.5 x 2.5 physical dimensions, a bigger capacity (50 mAh), and somewhat higher discharge currents. All other aspects of the battery are identical.
There are no distinctions between CR123 and CR123a batteries. They are the same size, however their names differ because CR123A is the most popular. You will find them used in many portable devices including cameras.
They are also known as 6V lithium batteries. These batteries are very common and inexpensive. There are several varieties of CR123 batteries on the market. Only some of them can be used in portable devices while others must be disposed of properly. Always try to buy CR123 batteries that say "for use in camera" or similar language on the box. This means they are suitable for use in your device and you don't need to worry about damaging your battery if you try to use it in something else.
The main advantage of using these batteries is their high capacity. A typical CR123 battery can hold up to 120 milliamperes for 1 hour. This means you can use your device for a long time without having to change the battery too often. Of course this depends on how much power your device needs so you should always read the manual to know exactly how long it can stay active without charging.
Another advantage is their low cost. You can find them everywhere from supermarkets to electronics shops. This makes them ideal for use in small devices where space is an issue.
The CR2032 has a thickness of 3.2mm, whereas the CR2025 has a thickness of 2.5mm. The CR2032 has a bigger capacity (mAh) to supply electricity to the load since it is 0.7mm thicker than the CR2025. A normal CR2032 has a nominal capacity of 225mAh, whereas a typical CR2025 has a nominal capacity of 160mAh. The CR2032 can be used up to 100,000 times while the CR2025 will last for about 50,000 cycles.
CR stands for "capacity rating". The higher the number, the more electricity the battery can supply before its maximum charge is reached. For example, a battery with a CR2032 battery can supply up to 20 minutes of continuous use before it needs to be recharged, while a battery with a CR2050 can supply 30 minutes of continuous use before it needs to be recharged. Batteries vary by their capacity and their price varies depending on their capacity.
Batteries may seem like a simple thing but there are many components inside that affect how much power they can deliver when you use them.
The CR2430 coin cell battery is somewhat wider than the CR2025 and CR2032 batteries. Security sensors that operate on coin batteries, such as the CR2430, are often compact and inconspicuous. However, because CR2430 batteries are wider, they cannot be interchanged with CR2025 and CR2032 batteries. Also, due to its width, a single CR2430 battery is not able to power multiple devices at once.
What exactly are CR123A batteries? The CR123A battery is distinguished by its 34.5 x 17mm or 2/3A cell size, lithium (LiMnO2) chemistry, and high 3V voltage, which makes it an excellent choice for lighting or lithium camera batteries. They are generally button-tops and are non-rechargeable main batteries. These are the most common batteries used in model railroads.
There are two types of CR123A batteries: fresh and dead. Fresh CR123As do not have any markings on them other than their name, while dead batteries will have visible damage to their casings. Because these are main batteries, they should be replaced before they fail so that you do not lose data or have to restart your project too soon.
These batteries are very easy to replace; all you need is a pair of small flat-head screwdrivers. First, remove the screws that hold the battery pack case together. Then, slide the pack off the rails. Finally, snap the old battery out of the case and put in the new one.
Although the thickness of CR2016 and CR2032 differs, they are otherwise similar. The capacity of the CR 2032 is 240 mAh, while the capacity of the CR2016 is just 90 mAh. The CR2032 can give 10 hours of use, however the CR2016 only provides roughly six hours, depending on the power used. The CR2032 costs about $1.50, whereas the CR2016 is about $0.50.
CR2032 batteries are used in many popular toys such as remote controls, flashlights, and alarm clocks. While these batteries are generally inexpensive, they do need to be replaced once they reach their end of life. This usually happens around after ten years, although this depends on how you use your toy or device. For example, if you use your remote control every week then it should be changed every other year, but if you rarely use it then you may be able to get by with changing it every three years or more.
CR2016 batteries are used in many small handheld devices including mobile phones and pagers. Like the CR2032, the capacity of the CR2016 battery is low (90 mAh), but it lasts for a long time. A charge from empty to full will last for about two weeks if used regularly. It is also affordable, costing about $0.50 each.
There you have it! That's all there is to knowing the differences between a CR2032 battery and a CR2016 battery.
