Everything You Should Know About CR2 Battery

Batteries are replaceable via plug-and-play. As long as you know what size battery your device requires, you will always get the correct type. The issue is deciding what kind of equipment you need or want to use.

Your decision will be influenced by the amount of power output, the device’s footprint, storage, and the amount of storage or type of battery you’ll require. It’s not always about how much power it generates, but rather why you need it and what your device’s demands are. In this article, we are going to discuss CR2 batteries

What is a CR2 Battery?

A CR2 battery is a lithium-ion cylindrical cell battery. The CR2 battery resembles a smaller version of a D Cell Battery or a can for a more visual comparison.

There are numerous uses for these batteries. They’re primarily found in cameras that require a high-capacity lithium battery, as well as a variety of industrial applications. Because of its numerous applications, this battery is quite popular and, as a result, might be challenging to come by. Panasonic, Duracell, and Energizer are just a few of the big and small companies that make them. This page will provide you with all of the information you require regarding the CR2 battery.

Are CR2 Batteries Rechargeable?

While the majority of CR2 batteries cannot be recharged, some can. A CR2 battery’s label will usually state whether or not it can be recharged. Non-rechargeable or single-use CR2 batteries are referred to as “primary batteries.”

Determine whether a CR2 battery is a “primary” or “secondary” battery. Attempting to charge a non-rechargeable battery (particularly a lithium battery) might result in the charger/device catching fire, exploding, or being destroyed. Using a suitable charger when utilizing a high-quality rechargeable battery is critical. If you charge your CR2 battery using the wrong or unsuitable charger, the battery may malfunction or stop working altogether.

How Long Do CR2 Batteries Last?

The lifespan of a CR2 battery is highly dependent on the battery’s manufacturing quality and application. Assuming the battery is new and obtained from a reputable supplier, there is still a wide variety of service life available depending on usage. A CR2 battery could last less than a month for a regular application that requires huge amounts of energy, such as a high brightness flashlight. Service life for a more passive application, such as a home security alarm panel, can be over a year with the right conditions. What you need your CR2 battery to do determines how long it will survive.

What Battery Is Equivalent to The CR2 Battery?

The KCR2, ECR2 1CR2, DLCR2, and 5046LC batteries are direct replacements and equivalents for the CR2. These are all primary or non-rechargeable batteries that directly replace the CR2 battery. The 15270 and 15266 batteries are rechargeable or secondary CR2 batteries.

These rechargeable CR2 batteries have a smaller capacity (mAh) than the non-rechargeable ones, but they will still fit in and power the same devices. The non-rechargeable version has a longer single-use life, but the rechargeable CR2 battery saves money in the long run.

Are CR2 and CR123A Batteries the Same?

The CR2 battery and the CR123A battery are not interchangeable. Because the CR2 battery is somewhat shorter than the CR123A battery, it will not fit in most CR123A applications. Furthermore, the CR123A battery produces around 50% more power than the CR2 battery, so even if you could fit a CR2 battery into a CR123A device, it would not give the entire amount of power required.

Your device will either perform poorly or will not function at all. These batteries have a couple of things in common: they’re both 3-volt batteries and constructed of lithium manganese dioxide.

The Differences and Which is Better

Let’s clarify specific terminologies and other battery principles before going into each battery.

First and foremost, we’re talking about lithium batteries. As a result, they should not be mixed with zinc batteries. If you have a variety of batteries, don’t mix them up and put different power cells in the same device.

Second, batteries typically use the unit mAh, or milliampere-hours, to denote how long they can work or stay charged. This is usually true when the battery is in use, and each battery’s charge can be extended by not using it constantly.

Finally, these lithium batteries lose around 5% of their charge each month. They’re losing charge even if they’re not in use. Remember when it’s time to replace your old batteries with new ones.

What Uses CR2 Batteries?

Military, commercial, medical, and consumer devices use the CR2 battery. The CR2 battery is utilized in weapon lights, optics, laser rangefinders, laser designators, and communications devices in a military application.

Alarm batteries and power for various devices are examples of medical uses of the CR2 battery. Lights, alarms, cameras, and storage backup applications are some of the industrial and consumer uses.

Where to buy CR2 Batteries?

The CR2 battery is a very common and widely used type of battery. This means that a number makes the batteries of different companies, and many other stores sell them. It’s essential to remember that not all CR2 batteries are made equal, and not all shops are committed to providing high-quality products. To prevent getting low-quality or counterfeit batteries, ensure you get them from a trustworthy supplier who only sells the best brands.

Is CR2 Better than CR123?

The CR123 battery is the more powerful of the two. Which one is superior, though, is always a matter of preference. You’ll have to utilize a certain sort of battery if your device requires it. If it requires a CR2 battery, no wishing will accept a CR123, as the two batteries are not interchangeable.

Long-term use and dependability are better with CR123. The CR2, on the other hand, maybe used in smaller tools and takes up less space. You must examine what you need from your equipment to save space with your battery storage. The CR2 will need to be changed more frequently, and additional replacement batteries will be required. This isn’t an issue when they’re small, but batteries can be costly. The charge output of the CR2 limits the number of rechargeables you can keep on hand.

The CR123s last longer and consume less energy than the CR2. On average, this results in a 60% increase in power. This applies to the battery’s use as well. When compared to CR2, CR123s will deliver higher power. If you use it in a flashlight, the light will be brighter. However, if lesser batteries power the device, this is irrelevant.

Conclusion

To recap, a CR2 battery is a cylindrical lithium cell with dimensions of 27mm x 15.6mm. They’re commonly found in old film cameras, shutter remotes, miniature flashlights, and other small electronic gadgets. The majority of CR2 batteries are single-use only and cannot be recharged. We hope that this article has given you a better understanding of CR2 batteries.
