CR1620 Battery Equivalent

Finding and buying CR1620 batteries is not difficult because almost all reputable and famous battery companies produce them.

It is commonly found in products that we use every day, such as digital watches, car keys, remote controls, credit card-sized devices, micro flashlights, and other items.

Consumers may become confused as not all manufacturers identify their CR1620 batteries with the same name. Therefore, details about the CR1620 battery equivalent will be covered in this article to help buyers choose the most accurate replacement battery.

What Is The CR1620 Battery?

CR1620 battery is a non-rechargeable lithium coin/button cell battery frequently used in products such as car keys, laser pens, remote controls, digital watches, credit card-sized devices, micro flashlights LED, toys, CMOS / motherboard batteries, medical devices, fitness appliances, and other related equipment use. It has a maximum shelf life of up to 10 years.

The CR1620 battery is commonly used in various electronic devices. The DL1620, ECR1620, BR1620, and KCR1620 are compatible replacements for the CR1620 battery.

CR1620 Vs. BR1620/LiR1620/ML1620 

It is quite rare to find a BR1620, LiR1620, or ML1620 battery in everyday life.

Compared with CR1620, the BR1620 has a slightly higher battery capacity, lower discharge current, significantly lower discharge rate, and wider temperature range. Depending on the exact chemistry, the BR1620 has a nominal voltage range of 2.8 to 3.0 volts and a cut-off voltage range of 2.25 to 2.0 volts.

The LiR1620 battery is a rechargeable lithium battery that can be recharged many times but has a smaller capacity than the CR1620 battery. The nominal voltage of a LiR1620 battery is between 3.6 and 3.7 volts, and some devices made to work with CR1620 batteries may not work with LiR1620 batteries. Self-discharge causes the LiR1620 battery to lose 5% of its capacity per month.

Close the compartment after placing it on top of the battery’s positive (+) connector to keep it in place. If you do not make good contact with the battery and spring, your battery may continue to die.

CR1616 Vs CR1620

CR1616 vs CR1620

CR1616 and CR1620 are both non-rechargeable lithium manganese oxide batteries. Although it has the same diameter of 16.0 mm, the height, discharge current and other characteristics are different.

  • CR1620 specs: 16.0 x 2.0 mm, 65-80 mAh
  • CR1616 specs: 16.0 x 1.6 mm, 50-55 mAh

While CR1616 batteries can fit into most CR1620 battery compartments, their use is not recommended as they have a lower capacity and smaller discharge/pulse current limits which can lead to malfunctions.

The CR1620 battery can be consumed by children and animals just like other small, shiny objects (including other lithium coin batteries). Because of this, these batteries are encapsulated.


What Are The Specifications And Features Of CR1620?

The CR1620 battery is compact and portable. These button/coin cells are 16mm x 2mm (or 0.62992 inches) and have a nominal voltage of 3 volts, but their cut-off voltage only drops to 2 volts before they completely die off, causing them to die. Your device has no power until you can get another CR-series battery!

The CR1620 battery can be discharged at a maximum rate of 1.0 mA, although this number varies widely between manufacturers. Typically, this rate is 0.1 mA. However, a higher discharge rate results in a decrease in the actual capacity of the battery.

Various CR1620 lithium manganese-dioxide batteries are available, and depending on the model, their self-discharge rates range from 1-2% annually to 1 percent or less, making them suitable for use in various devices. However, increasing the temperature of the battery also increases the rate of self-discharge.

In addition to the CR1620 and 5009L names, the CR1620 (IEC standard) batteries are also known as ECR1620, DL1620, VCR1620, and others. However, the majority of manufacturers use the CR1620 label.

Can I Use A 2016 Battery Instead Of A 1620?

It won’t fit in the battery socket; that’s for sure. This is true because CR2016 is slightly larger and thinner than CR1620. CR1620 is 1.6mm thick and 20mm in diameter. 

Since the CR2016 has a diameter of 20 mm, it cannot be placed in a holder made to hold the CR1616. Because it is simply too broad, you cannot use CR2016 as the CR1620 battery alternative. 

Is 1620 Battery The Same As 1632?

There is no difference between the 1632 and 1620 battery types as they have the same volts and appearance. Depending on the application, switching from a CR1632 to a CR1620 battery should cause no harm. However, you will only get less useful performance if you use 1620 instead of 1632.


Understanding each battery type, its features and differences is essential to choosing the right battery for your device. 

Despite the similarities of the CR1620 battery equivalent, they still differ on some points. It might be weight, thickness, durability, capacity, or price. In addition, each battery is also mainly used in some specialized devices. 

After our article, we hope you will have a better understanding of the CR1620 battery and find the CR1620 battery replacement you need.
