AA, CR2, and CR3 Batteries - What's the Difference?
You've probably heard the names AA, CR1, and CR3 batteries before, and wondered if they were the same thing. Fortunately, there are some important differences between these three types of batteries. Learn how they differ and which ones are best for your needs in this article. Read on to learn more about these three types of batteries and how to tell the difference between them. After all, it's important to be able to recognize the difference.
Alkaline 3.7V batteries have similar sizes and capacity to their silver oxide counterparts, but differ in chemistry and discharge characteristics. These batteries are cylindrical in shape and have physical dimensions of 14.5 x 50.5 mm (approximately 0.57 x 1.99 inches). They are usually labeled 'AA' but may be designated differently in different countries. The AA chemistry is more common and is used in a wide variety of applications.
Unlike the AA or AAAA cell, a cylindrical cell's nub terminal is located at the bottom of the cap. The side of the can does not serve as a terminal, and can have either a positive or negative polarity, depending on chemistry and the sealing on the case. Cylindrical cells also go by the names bobbin, spiral, and coiled. They have the same physical size as an AA battery and are popular for small electronics.
CR1 Alkaline 3.7V batteries have an average height of three-quarters of an inch, making them an excellent choice for consumer electronics. They are commonly used in cameras and other devices that require 1.5 volts of power. The CR1 battery has a solder tag on the positive and negative terminals, so it can be soldered directly into your equipment. The CR1 is available in three different sizes and provides a range of voltages.
In photography, CR1/3N batteries replace LR44 batteries. The round cell is approximately one eighth of an inch in diameter and features a metal cap and negative terminal. Button cells are also commonly used in clocks, timers, and electric watches. They carry the IEC suffix "W" if they meet watch standards. Other common uses for CR1 Alkaline 3.7V Batteries include toys, calculators, and laser pointers.
CR2 Alkaline 3.7V batteries are cylindrical cells with lithium chemistry. This type of battery is a smaller version of the D Cell and is often used in cameras, but it also has numerous industrial applications. Various brands produce CR2 batteries, and the following chart compares the most common CR2 batteries. It's important to note that these batteries differ in their performance and shelf life, so it's helpful to check the specifications of the batteries you're considering.
CR2 alkaline 3.7V Batteries are extremely common, so you can find a wide variety of retailers selling CR2 batteries. Keep in mind, however, that not all batteries are created equal and not all retailers have the same commitment to quality. Make sure to buy your batteries from a reputable retailer to ensure the best performance. These batteries will last a long time, and will continue to work for a long time.
CR3 alkaline 3.7V rechargeable batteries are commonly single cells with a nominal voltage of three volts. One example is the Duracell Ultra CR3 which is composed of two 3 V AA size lithium cells connected in parallel. Unlike other rechargeable batteries, CR3s are designed to be longer-lasting. Some batteries even feature a third smaller charging terminal. Moreover, some RCR3s are incompatible with chargers from different brands.
Another type is the CR2 battery. This is the smaller version of the CR123A. The CR2 battery will not fit in many CR123A applications. Another difference is the output of the two batteries. The CR2 battery is able to deliver 50% less output than the CR123A battery. Therefore, when used in such a device, the CR2 battery will not work properly. The CR2 battery is made from manganese dioxide and lithium.
CR4 alkaline 3.7V battery is the most common type of rechargable battery. This type of battery is designed to provide approximately 3.7 volts of power. Its name is derived from the LR61 battery, which was first introduced in 1901. This battery contains six LR61 cells. These cells are similar to AAAA cells, but they have posts that are marked with the cell number.
The CR1 battery is one-third the height of an alkaline N cell. Stacking three CR1 cells creates a battery with the same dimensions, but with a higher terminal voltage: 9 V. Some CR4 batteries boast a 10 year shelf life, while others offer a shorter life span. The most popular CR2 batteries are the CR2 or CR123 cells, which can be interchanged with CR4 alkaline 3.7V batteries.
CR2 batteries are cylindrical cell batteries with lithium chemistry. They look like cans and are commonly used in cameras. They also find applications in various industrial uses, such as memory backup. They are manufactured by different manufacturers and retailers, but not all of them are dedicated to quality. To ensure you get a quality CR2 battery, buy it from a reputable retailer. Read on to learn about CR2 batteries.
The two common CR12 alkaline 3.7V battery types are the C2 and CR12, which are interchangeable. While C2 is usually not referred to as C2, some small manufacturers offer identical CR2 batteries with the C2 designation. C cells, however, are often confused due to their retail packaging. Some retail packs of two C batteries may say C 2 on the top of the package. That is not a C2 battery, but the two cells contained within the pack.
CR16 alkaline batteries are a popular type of non-rechargeable battery. They are used in a variety of devices that typically require a three-volt output, such as flashlights, digital cameras, and GPS devices. CR16 alkaline batteries are typically 400-600 mAh in capacity. These batteries have a long shelf life and can last several years with proper use.
The CR16 chemistry is the most common type of alkaline 3.7V battery. The chemistry is LiFePO4 and it is safe for your electronic devices. CR16 batteries can deliver 10 Ampere-Five (Amps) for up to 15 hours and are used most commonly in flashlights. Because these batteries are made for flashlights and small appliances, they are often smaller and lighter than RCR123A batteries.
CR2032 batteries are lithium-ion coin cells that are used in many devices. These batteries typically have a capacity of 240 mAh and operate at three volts. Often, they are used in small, non-rechargeable electronic devices. These batteries are commonly found in things such as calculators, early digital watches, and even a button battery that powers blue and white LED flashlights. You can find a large selection of CR2032 batteries at Battery Junction.
These batteries are lightweight, low-cost, and high-density. They are also easy to stack to produce higher voltages. However, because they are non-rechargeable, you should never store them outside of the intended use. CR2032 batteries are available for about $0.35 per cell, while CR123 batteries can cost up to $1.50 each. But, if you are concerned about their environmental impact, you should know that these batteries are considered safe to use.
Lithium-ion batteries are the preferred choice for consumer electronics because they can withstand extreme temperatures, and are also available in a wide range of sizes. But lithium batteries are not suitable for general-purpose use. They are considered hazardous waste. Read this guide to learn about the advantages of lithium-ion batteries. This article will discuss how they differ from their alkaline counterparts. Listed below are some advantages and disadvantages of lithium-ion batteries.
CR321 alkaline 3.7V batteries are interchangeable with CR123A cells. Their size is approximately the same as two R6 (AA) cells placed side-by-side. This is a common type of battery used in film and digital cameras, and is also available in rechargeable versions. These batteries are not as long as their corresponding AA or AAA counterparts, and are often used in devices that are not explicitly designed for them. However, these batteries are not manufactured by Duracell, and they are no longer available in retail stores.
Older batteries are made of lead-acid or alkaline chemistry, and have a nominal voltage in increments of two volts. In contrast, the newer CR321 Alkaline 3.7V batteries are much more durable and last longer than their predecessors. These batteries are compatible with most electronic devices, and are a good choice for a variety of applications.
