CR927 Battery Equivalent: Guide to Compatible Replacements

Introduction

The CR927 battery is a small, non-rechargeable 3V button cell known for packing high-energy density in such a small form factor. The term CR indicates that it is a lithium-manganese oxide battery and is also round. As for the 927 part, it shows the dimensions, whereby it has a diameter of 9.5mm and a height of 2.7mm. These are all essential features to keep in mind when seeking a CR927 battery equivalent. 

CR927 Battery Technical Specifications 

CR927 Battery Applications 

The CR927 batteries come with multiple uses. This includes:

• Watches and calculators
• Electronic toys
• Mini LED lights 
• Medical instruments such as glucose meters
• Remote controls and key fobs

It is vital to note that these batteries are single-use only. Do not recharge the battery if it is low, as this may cause leakage or an explosion. Make sure to properly dispose of these batteries and keep them away from children, as they can be a choking hazard. 

Why You Might Need a CR927 Equivalent

By the time you are looking for a CR927 battery equivalent, it is possible that the original CR927 is out of stock. This is a good reason to start looking for alternatives that can do the same job. 

Although less common, a manufacturer can discontinue the production of the CR927 batteries. This is why some people opt for the CR027 battery equivalents. 

Another reason is the cost-effectiveness of buying from less popular brands. For example, you can get the same battery at a lower cost when you don’t buy from Duracell. However, make sure you are still getting high-quality batteries and not just buying for the sake of saving. 

Top CR97 Battery Equivalents

You will come across multiple batteries that can work as the CR927 battery equivalent. Here is what you should consider getting, as they have been tested and found to be the best alternatives. 

• DL927: This is an excellent battery from Duracell. It is good in terms of offering the best performance, just as the standard CR927. 
• ECR927: This is what Energizer, as a brand, uses to label the standard CR927, making it a direct replacement. 
• KCR927: This is another label of the CR927 battery you can expect from other battery manufacturers. 
• LM927: This is also a good equivalent battery with good value. It is mainly compatible with various devices using the 927 battery. 
• BR927: This battery is another alternative for low-drain devices or applications that operate in extreme temperatures. Expect it to have a longer shelf life than the standard CR927 battery. 

How to Identify a Suitable CR927 Equivalent

Now that you know about the options available for a CR927 battery equivalent, how do you make sure it is the right one? We recommend matching these batteries based on their chemistry, dimensions, and voltage. 

Consider the core specifications 

The dimensions are important for getting a battery equivalent. The CR927 battery has a 9.5mm diameter and a 2.7mm height. Make sure that the replacement has exact dimensions to fit in the device better. 

The CR927 battery also comes with a voltage of 3.0V. This means the equivalent battery should have a similar voltage. Sometimes you come across a similar-sized battery, and you think they have the same nominal voltage. That might not be the case. Check the specifications sheet to understand their performance features first. 

The battery chemistry is lithium manganese dioxide. So, it is best to consider this also, as it determines how well the battery performs in the device. 

Performance & Lifespan of CR927 and Its Equivalents

The overall performance of the CR927 battery largely depends on various factors. This includes the chemistry, capacity, the demands of the device it is powering, and discharge characteristics. 

Performance Features

The CR927 3V lithium battery has a stable 3.0V output throughout the discharge cycle. Such a feature makes it suitable for sensitive electronics that need a consistent voltage. 

As for capacity, it ranges from 25 to 40 mAh, depending on the brand. It is built for low-current applications. Expect it to also deliver on a discharge current of around 0.05mA. So, using it with high-drain devices depletes it faster. 

Another good thing about the battery is that it can operate over a wide temperature range. The overall performance and capacity may be affected if you use the battery at extreme temperatures. 

The main factors affecting the battery lifespan include:

• Temperature: Always store or operate the CR927 battery in its ideal temperature range. If you do outside the range, expect a reduced lifespan. Extreme heat generally accelerates the chemical reaction, while extreme cold inhibits the reaction. 
• Discharge rate: If the battery is consistently discharged at a high rate, then it will have a shorter lifespan. 
• Storage conditions: The battery should be stored in a cool, dry environment. Improper storage may cause a short circuit or reduced shelf life.

When and How to Replace a CR927 Battery

When to Replace

Here are some of the indicators that it is time to replace the CR927 battery:

• There is reduced device performance. For example, if it is a watch, the display dims, or a remote starts working only intermittently. 
• An unexpected power drain indicates the battery has been in use for years and now needs to be replaced. 
• If the device stops working, the battery is fully drained and needs to be replaced for it to start working again. 
• Test the battery by doing a voltage test. If it shows a voltage of 2.5 volts or less, replace it. It should be close to the nominal voltage of 3 volts. 

How to Replace

Replacing the old CR927 battery is easy. Here is how to do it on most devices. 

1. Open the battery compartment. Most devices come with a snap-in cover that can be opened with a small screwdriver. Some might need a special tool to open the case, so get them before you start working on the compartment. 
2. Remove the old battery from the compartment. You can simply tip the device to remove the battery, or use small plastic tweezers to lift it out. 
3. Clean the terminals with a dry cloth or cotton swab to ensure the battery contacts are clean and the connection is good. 
4. Insert the new battery and ensure the correct polarity is maintained. The positive side is usually marked and will often face upwards, but you can refer to the device manual for more details. 
5. Close the compartment and turn on the device. Check if it is working properly. If not, make sure the battery is correctly aligned and new.

Conclusion 

The CR927 battery is good in many ways, especially the energy density. If you are seeking a CR927 battery equivalent, it should also be as good. In addition to the performance features, consider the dimensions. This determines if the alternative battery will fit in the battery compartment and perform as well.
