Have you ever seen a coin-sized battery? Yeah, here comes the CR2025 battery, which looks exactly like a coin. It is, in fact, a small lithium battery.
Generally, you will find CR2025 batteries on a wide range of devices like calculators, heart rate monitors, LED lights, etc. If you happen to have a device like this, you will also need a decent coin battery to power it up. And you need to read this CR2025 battery review until the very end if you want to gain the most comprehensive knowledge on this topic.
What is a CR2025 Battery?
A CR2025 battery is basically a lithium-ion battery that comes with a diameter of 20mm and a thickness of 2.5mm. Generally, this battery has a high current of 3 Volt power. And, the capacity is typically up to 170mAh.
Another key point to be noted, you cannot recharge the battery as it counts as a disposable battery. So, after using a CR2025 for the first time, you will not be able to use it again.
If you look at the reason why it is made with a coin-looking design, you will understand the portability of the battery. The slim design makes it easy to fit into a small portable device. Therefore, you don’t have to face any hassle using it on small devices.
CR2025 lithium cell batteries cost more than alkaline batteries. But, that should not be the concern, as lithium cells last a lot longer and weigh very little. Besides, lithium coin batteries work at a wide range of temperatures.
Panasonic CR2025 Battery
Panasonic CR2025 battery is one of the best batteries on the market now as an economical option. It comes with a high voltage and has a high shelf life. Let’s look at its other features below.
High Capacity
If you look at an ordinary battery, its operating range is quite low. But, in the case of a Panasonic CR2025 battery, you will get 150mAh to 170mAh capacity, which is usually given as the actual capacity. As can be seen, the 170mAh capacity is a lot for a coin-sized lithium battery.
Multiple Compatibility
Primarily, you will want to buy a Panasonic CR2025 battery for its regular use. But, you may not know its vast usability. You can use the same battery by replacing other similar batteries.
The first thing to remember, the “2025” refers to the battery dimension. To clarify more, this code actually shows the 20mm diameter and 2.5mm height. So, you can easily exchange a CR2025 battery with 5003LC, 208-205, LF12V, SB-T14, LM2025, L12, CR2025-1W, BR2025-1W, BR2025, KCR2025, ECR2025, DL2025B, DL2025, and other 2025 lithium batteries.
More Durable
Have you used any Panasonic CR2025 before? If your answer is yes, then we don’t need to clarify the hardiness of this battery. As the battery comes with a stainless steel or metal body, don’t worry about its durability. The chances of breaking a CR2025 battery are nearly impossible unless you use high force, such as a hammer.
Sometimes you will get a nickel-plated shell in your CR2025 Panasonic battery. But, they are not very common on the market. However, the nickel shell is considered the most durable outer cover for a CR2025 battery pack. Usually, no leakage is reported in less than five years for a nickel-made shell.
Diverse Use
You can use the Panasonic battery on any compatible device that supports a 2025-sized battery. If we name the compatible devices, the list will include pocket calculators, transmitters, heart rate monitors, hearing aids, Polar and Timex watches, various wristwatches, normal LED lights including tea lights, car key fob remotes, motherboards, etc. and a lot more. In this case, the regular use of a CR2025 li-ion battery is increasing day by day.
Safety Certified
One of the most important things about using a battery is its safety. Definitely, the Panasonic CR2025 is a safety-certified battery. If you buy this branded battery, your battery will come with safety certifications from several standards, like UN 38.3, RoHS, CE, UL, ISO 9001, etc. Yet, you should check its safety certifications before buying the battery to ensure you are getting the original battery.
Long-Term Warranty Service
Though the warranty period and service quality vary based on different companies, you are typically guaranteed to get a warranty for a longer period for such a product. Surprisingly, you will get five years of warranty from Panasonic for the battery!
Here is a quick tip for you. Always check the backside of the package of the Panasonic CR2025 battery for the manufacturing date and warranty date. Try to purchase the latest manufactured battery to get a long-lasting output. Besides, it will increase your warranty limit.
Pros
- It comes with a lightweight coin-looking design
- High voltage output
- The energy density is very high compared to the size
- Slow discharge increases the usable time
- Great leakage resistance is included
- Ensures long-term reliability
Cons
- This battery is allowed for single-use
- Non-rechargeable
Calculating the Runtime of A CR2025 Battery
The CR2025 battery is normally used for portable electronic devices, but you certainly don’t want to have to change it too often. That’s why the runtime of such a battery is important.
However, the battery life depends on many things like dynamic loads, discharge rate, operating temperatures, etc. The problem here is that these parameters differ for different devices. Now, we will calculate the normal run time of a standard device and show you how to do it yourself.
Suppose you use a device that takes a normal load of 20mA current and the working temperature is 20 degrees Celsius. If we consider your battery capacity as 163mAh, you need to divide the battery capacity by the load current, which is 163/20. So, the result will be 8.15. In other words, you can continuously use it for 8.15 hours.
Similarly, when you use a device with a 10mA current, this battery can approximately run for 16.3 hours. However, the time can vary due to the change of operating current and temperature. To avoid this problem at the maximum rate, try to measure using an average temperature and output value.
Conclusion
A battery starts with “CR”, indicating it is not only a lithium-ion battery but also one that contains chromium. So, it is slightly different from a regular 2025 battery. Although this is true, there is no confusion about the excellent quality of the Panasonic CR2025 battery. We hope this battery will not disappoint you in the long run.
