Best CR1220 Battery Equivalents in 2025

Introduction

If you use a watch, clock, or toy, you have likely encountered the CR1220 battery. It is a common type of coin cell battery found in many everyday devices.
The CR1220 battery has dimensions of 12.5mm in diameter and 2mm thick, making it easy to find devices that would work with such a small form factor battery. You should see the battery inscribed as CR1220 on the positive terminal to identify it easily. The idea is always to replace it with the same battery.

The CR1220 battery is characterized by a low self-discharge rate, long shelf life, and the ability to last for 10 years in storage. The battery can keep performing well thanks to the lithium-manganese dioxide technology powering it.

What if you cannot find a CR1220 battery in a store nearby? In that case, you can choose a CR1220 battery equivalent. This battery type will have similar dimensions to fit in your device’s battery compartment and still offer similar performance so that it powers the device sufficiently.

Common Applications of CR1220 Battery

Whether it is the CR1220 battery or the CR1220 equivalent battery, they all have an impressive number of applications. Such include;

• Wristwatches, clocks, and timers
• Key fobs mostly for car key remotes
• Hearing aids and other precision medical devices
• Glucose monitors and digital thermometers
• Calculators

Thanks to its versatility, you should expect to come across many other devices using this battery type.

Why It Matters to Have the Right CR1220 Battery Equivalent

When we recommend getting a CR1220 battery equivalent from Duracell, we know that it will be the perfect replacement. This is because of the following:

Compatibility – When you are looking for a battery equivalent, the overall compatibility, such as the voltage and current, are very important. In this case, the equivalent models will also have a 3V voltage capacity vital for the device’s performance.

The fit – Of course, the size of the CR1220 battery equivalent should be the same as the original so that it can fit in the battery compartment correctly. Anything too big or small will not have the right contact with the terminals, and the device will not work as good.

Lifespan — The CR1220 battery equivalent from Energizer should have the same capacity. The capacity determines the battery’s lifespan. If you get the same capacity, you are promised similar performance.

Device performance — Working with some devices requires precision. If the battery is not able to supply steady power like the CR1220 battery, it could lead to erratic readings. This is another reason to have the correct replacement.

Safety first – Let us say you get a CR1220 3v battery equivalent, but it has compatibility issues. In such a case, you risk issues such as leaks, overheating, and sometimes shortcircuiting. You are better off choosing a compatible equivalent battery to get the right performance with no risks.

What are the CR1220 Battery Equivalent Options

If you are seeking a button battery CR1220 equivalent, there are a couple of options in the market. However, we focus on a few that will be a good fit, so you do not have to worry about compatibility issues.

DL1220

This one comes from Duracell and is made to be the exact replacement for the CR1220. This is thanks to having similar dimensions and capacity. Expect the battery to have consistent voltage levels, which you need for stable performance.

BR1220

Other than the CR1220 battery Duracell equivalent mentioned above, you get this one from Panasonic. The biggest difference is that the BR1220 is not recommended for high-drain applications, but it is still a good equivalent with a longer lifespan.

ECR1220

Energizer did a good job with this one, as it is a replica of the CR1220 in terms of dimensions and specifications. Full compatibility means you do not have to worry about inconsistent energy outputs. Go ahead and use it in fitness trackers, key fobs, and other devices that use the CR1220 battery.

KCR1220

This is a less common CR1220 battery equivalent, but it is still just as good for its job. It features an identical voltage and size to the CR1220 battery, so compatibility is not an issue. We recommend it for cases where you cannot use alternatives from major brands, and you urgently need a CR1220 equivalent battery.

How Safe Is It to Use CR1220 Battey Equivalents?

Before someone can consider getting an equivalent to CR1220 battery, safety can be a concern sometimes.

You should know that the equivalent batteries are still just as good but come from a different manufacturer. You should be good if the equivalent battery has the same size, voltage, and chemistry as the original CR1220 battery.

So, before you can buy the battery equivalent, make sure to check the specs. Confirm whether the Sony CR1220 battery equivalent has the same specs as the CR1220 battery.

Other than the specs, the brand also matters. For example, choosing a Panasonic CR1220 battery equivalent as an equivalent battery rather than selecting a brand no one has ever reviewed or is relatively too new in the market.

Longevity of CR1220 Battery and Its Equivalents

The CR1220 battery has a good lifespan. However, this depends on the device’s usage and power needs. For most applications, expect it to last up to 3 years.

The battery can last up to 10 years if stored unused. That is a long time, and you would probably use it before the 10 years elapse.

So long as you can keep the battery operating within the right temperature, it should give you a long-lasting performance. It should not be hard to achieve the right temperature for the battery.

The same logic applies to the CR1220 battery equivalent. Proper use will ensure their long life.

Where To Buy CR1220 Battery Equivalents

At this point, you are already looking for a CR1220 battery equivalent nearby. We recommend checking out popular electronics stores in your area. You can also consider the convenience stores as they often stock such battery types.

Online retailers like Amazon, eBay, and Walmart are good choices. They will have various options for you to consider, and depending on the store, they can deliver fast.

Hardware stores such as Home Depot or any other store close to you will likely have a CR1220 Duracell battery equivalent or one from other top brands already mentioned.

Conclusion

Looking at the CR1220 battery equivalent options above, we can see that these are batteries you can easily find in the market. Sometimes, you have to do more research to see if the brand is not among the big names in the industry before buying. Make sure to install the equivalent batteries correctly if you want the right performance. If you can choose correctly, you will not notice that it is a different battery as the device will perform optimally as expected.
