One of the most often used non-rechargeable lithium 3.0V button or coin cell batteries is the CR1220. It is usually found in keyless remote controls, LED flashlights, calculators, thermometers, medical scales, PDAs, heart rate monitors, cameras, and other electronic devices, among other applications. If you’re looking for a reliable resource for reliable information, look no further than this informative guide for cr1220 battery equivalent.

Batteries with the CR1220 suffix are far more prevalent than those with the same capacity. So you might be thinking, what can I use instead of CR1220? Although all equivalents have the exact physical dimensions, each has a unique set of properties according to their chemistry, such as a varied capacity, voltage output, operating temperature, and so on.

The other replacements of CR1220 include DL1220, ECR1220, BR1220, VR1220, DL1220B, KCR1220, LM1220, 5012LC. If you are unsure which dimensions or chemistry will suit your device, look at the battery cross reference chart. It is a fantastic deal because of its outstanding dependability mixed with its low price.

CR1220 Batteries and Its Equivalents Features 

Application, temperature, equipment type, and so on all affect battery capacity and properties. Though, CR1220 and its equivalent batteries have some specific characteristics, which we mentioned below:

Reliability Over Time

Components of active electrolytes are used in Cr1220. Modern technology additionally encapsulates these materials to reduce self-discharge and ensure ten-year storage. Because of this, you will not have to be concerned about it. Lithium manganese dioxide coin cell batteries, such as Toshiba CR1220, are well-known for their dependability and extended lifespans.

High Energy Density Yet Low Weight

The CR1220 battery weighs only 0.8 to 0.10 grams, depending on the brand. But they are strong and have a lot of energy, and their voltage rating is about double that of the others. In terms of power output, Panasonic CR1220 is the best in the business.

CR1220 batteries also have negative electrodes made of lithium and positive electrodes made of manganese dioxide. Of course, they’re carbon monofluoride.

Enhanced Discharging Capabilities

Capacity 35-40 mAh, standard discharge current 0.05-1.01mA, and maximum continuous discharge current of 1mA are typical characteristics of this type of battery. In addition to being leak-proof and maintenance-free, LiCB CR1220’s latest battery technology is a pleasant addition.

Assured Voltage Stability During Discharge

CR1220 button or coin cell batteries indeed have a nominal voltage of 3.0 Volts, with a cutoff voltage of 2.0 Volts on average. Steady battery temperature and load assure stable current discharge to the devices.

Longer Shelf-Life

According to its self-discharge rate, the average shelf life of the CR1220 battery ranges between 4 and 7 years, and other models have a shelf life of up to ten years in the market. 

For example, Maxell CR1220 batteries have an annual discharge rate of less than 1% at room temperature and hold up to 80% of their initial charge. If you want a similar small-size battery with a longer shelf-life, you can go for CR1216 battery equivalents.

Understanding The Naming Convention

You may notice some strange numbers and letters appear on coin cell batteries, and it is essential to understand them. On the battery, two letters are followed by three or four digits. 

The first letter denotes the battery’s type, and the second is only a form of shape indicator. Here are the multiple chemistries.

  • B – contains Carbon-monofluoride(Lithium);
  • C – contains Manganese-dioxide(Lithium);
  • G – contains Copper-oxide(Lithium);
  • L – Manganese-dioxide(Zinc);
  • M,N – Mercuric-oxide(Zinc);
  • P – Oxygen/Zinc (zinc-air battery);
  • S – Silver-oxide(Zinc).

Analysis and Recommendation for Replacements for the CR1216 Battery

In most cases, the CR1220 battery is interchangeable with ECR1220, DL1220, VR1220, and 5012LC batteries. Below we’ve compiled all information on these high-quality alternatives to save you time.


Compared to other primary cells, ECR1220 lithium batteries have a better energy density, a higher cell voltage, and a longer shelf life due to minimal self-discharge. It is also the popular equivalent of Cr1220. Energizer ECR1220BP provides precise energy that is exactly aligned to their specific tasks.


BR1220 and CR1220 batteries are commonly interchangeable. For high-drain applications such as keyless LED torches, remote controllers, etc., CR1220 batteries are significantly superior. Conversely, BR1220 batteries are better suited to applications requiring high temperatures.

Also, BR1220 batteries like Hillflower BR1220 have a reduced self-discharge rate (1% annually), making them suitable for motherboard batteries. For a cell that will be used for at least a decade, there is no reason to save a few dollars/euros. Like CR1220 batteries, BR1220 batteries can last longer than CR1220 batteries.


DL1220 is replaced by a 3V lithium coin cell battery (CR1220). Among its many uses are keyless access, electronic books, and glucose monitoring. Because the dimensions of the two batteries are identical, you can simply swap out the Cr1220. One of Exell’s best-selling batteries, the Exell EBDL1220 has an Amperage of 38mAh and is known for its high performance.


In addition to flashlights, calculators and toys, KCR1220 lithium button coin batteries are used in a wide range of other devices with a 40mAh capacity, such as cameras and toys. For example, most users recommend Camelion 5 X Kcr1220 for their low discharge rate.


Here LM means Lithium Manganese/Zinc in the battery. It’s an r3.6V rechargeable lithium battery. Hillflower LM1220 is one of the high-quality LM1220 batteries, which is convertible with CR1220.


5012LC has been specifically engineered to function optimally in a temperature range of -20°C to +60°C. This alternative of CR1220 is not very familiar to users. The cells discharge at a constant resistance of fewer than 2.0 volts per cell to get the stated capacity in Eunicell 5012LC.

Comparison Chart of the CR1220 Batteries

As you can see in this table, there are many different CR1220 batteries on the market, each with its own unique set of characteristics and specifications.

Are 1220 and 1225 Batteries Interchangeable?

Yes, The 1220 and 1225 batteries are interchangeable in most circumstances due to their similar 12.50 mm size.

How Long Do CR1220 Batteries Last?

Normally, cr1220 lithium button cell batteries have a shelf life of up to ten years.

What Are the Key Features and Specifications of D-Cell Batteries?

D-cell batteries are popular portable power sources known for their longevity and reliability. With a standard size of 1.34 x 2.42 inches, these cell batteries offer a consistent voltage output of 1.5 volts. Their key features include high energy capacity, making them suitable for heavy-duty devices like torches, radios, and larger electronics. D-cell batteries are a cost-effective choice and commonly available, making them a convenient option for various applications.

What Type of Applications Can Benefit From Using a CR1220 Battery?

CR1220 batteries are commonly used in devices with low power requirements, including calculators, watches, remote controls, medical equipment, and even toys. The small size and long shelf life of CR1220 batteries make them ideal for applications that require low power and long-term storage.

Are CR1220 Batteries Rechargeable?

The CR1220 and the ML1220 are both the same size and voltage, but the CR1220 is not rechargeable, whereas the ML1220 is.

Final Thoughts

A growing number of electronic items are powered by cr1220 battery equivalents as they become smaller and more convenient to carry along. I hope these tips help you avoid overpaying for a product that isn’t worth the money and won’t last. 

Remember that asCR1220 batteries are small and shiny objects that can be ingested by children and dogs, which can be extremely harmful. So please keep it away from them.
