CR1620 Battery Equivalent – List & Buying Options

CR1620 Battery Equivalent

Key Takeaways

  • The C in the product title denotes the chemical technology in the battery (Lithium), while the R shows that the battery is disk-shaped or round.
  • The first two numbers in the product name represent the battery’s diameter, and the last two represent the battery’s thickness.
  • From 1996, manufacturers no longer put mercury in button-size batteries.
  • Coin or button-size batteries aren’t rechargeable. They instead rely on lithium chemistry to give a current of 3 volts.

After serving you for a decent time, your CR1620 battery has depleted its charge, and now it’s time to acquire a new one. Unfortunately, the local store is out of your preferred CR1620 batteries. It can be frustrating when you don’t know a perfect equivalent replacement.

In this article, we will identify what other variations of the coin battery you can use interchangeably with the CR1620 battery.

What Is a CR1620 Battery?

The CR1620 battery is a coin-sized lithium-ion battery that provides 3V to electronic devices. Manufacturers designed it for small electronic devices that demand high power output. 

These electronic devices include:

The CR1620 lithium coin is widely used in these devices because it provides the following benefits.

  1. It produces enough voltage (3V) to meet the power needs of the devices.
  2. It can withstand harsh temperature conditions.
  3. It has a long shelf life of 10 years, meaning that the rate of self-discharge is minimal.
  4. It is environmentally friendly because it has no mercury. 

In case you’re wondering what the letters and numbers in the product name mean, they are code for the chemical composition, battery shape, and dimensions. 

C – Lithium

R – Round shape

16 – 16mm Diameter 

20 – 2.0mm thickness or height

CR1620 Equivalent CR2032

The CR2032 has an impressive capacity to store charge, meaning it can keep more energy needed for your device. However, it’s not a suitable substitute for the CR1620 battery as it has a bigger diameter of 4mm and is 1.2mm thicker than the CR1620.

Here are more distinguishing features between the two batteries.

  CR1620 CR2032
Voltage 3V 3V
Current Capacity 70mAh 210mAh
Dimensions 16mm wide and 2mm thick 20mm wide and 3.2mm thick
Weight 1.3 grams 3.0 grams
Chemical Composition Lithium Manganese Dioxide Lithium Manganese Dioxide
Shelf Life 10 years 10 years

CR1620 Battery Equivalent CR2016

Despite having the same voltage, chemical composition, and shelf life, the CR2016 isn’t a suitable equivalent to the Cr1620 battery. The difference lies in the dimensions, where the CR2016 has a 4mm wider diameter and 0.4mm less in thickness than the CR1620.

Here is how the two batteries compare.

  CR1620 CR2016
Voltage 3V 3V
Current Capacity 70mAh 90mAh
Dimensions 16mm wide and 2mm thick 20mm wide and 1.6mm thick
Weight 1.3 grams 1.9 grams
Chemical Composition Lithium Manganese Dioxide Lithium Manganese Dioxide
Shelf Life 10 years 10 years

CR1620 Battery Equivalent to CR2025

The CR2025 battery is not an ideal equivalent to the CR1620 battery. It is thicker and hence would not fit in the device properly. The following is a breakdown of how the two batteries compare.

  CR1620 CR2025
Voltage 3V 3V
Current Capacity 70mAh 150 – 170mAh
Dimensions 16mm wide and 2mm thick 20mm wide and 2.5mm thick
Weight 1.3 grams 2.6 grams
Chemical Composition Lithium Manganese Dioxide Lithium Manganese Dioxide
Shelf Life 10 years 6 – 8 years

CR1620 Battery Equivalent 1632

At first glance, the CR1620 and the CR1632 batteries may look alike. Still, some subtle differences distinguish the two coin batteries. Here is how the two batteries compare.

  CR1620 CR1632
Voltage 3V 3V
Current Capacity 70mAh 130mAh
Dimensions 16mm wide and 2mm thick 16mm wide and 3.2mm thick
Weight 1.3 grams 1.8 grams
Chemical Composition Lithium Manganese Dioxide Lithium Manganese Dioxide
Shelf Life 10 years 10 years

The CR1632 is a good fit, and you can use it as an equivalent of the CR1620. The CR1632 provides more charge for the same price and is only 1.2mm thicker. As long as your device allows the extra space, it is a suitable equivalent.

CR1620 Battery Equivalent Duracell

Duracell is a well-known brand with long-lasting batteries. The CR1620 is compatible with the following Duracell batteries.

  • Duracell DL1616BPK Lithium Coin Battery – It is a CR1616 battery meaning it has a 16mm wide dimension and 1.6mm thickness. These dimensions almost complement those of the CR1620; hence it is a good equivalent of the battery. The only problem is that it has a charge capacity of 50mAh, which is lower than the Cr1620.
  • Duracell 1632 3V Lithium Battery – It is a CR1632 battery. It has a 16mm diameter and 3.2mm thickness. The battery is a good equivalent for a device with ample space to accommodate the extra 1.2mm thickness.

CR1620 Battery Equivalent Energizer

Energizer offers quality but a lower price than competitor Duracell. If you’re looking for a good replacement for your CR1620 battery, here is a list of equivalent Energizer batteries.

  • Energizer CR1616 Lithium Coin Battery – It is a good equivalent for CR1620 because its dimensions allow easy replacement. In addition, the Energizer batteries can withstand temperatures of -22°C to 140°F.
  • Energizer Lithium Button Cell 3V Cr 1632 – The battery is equivalent to the CR1620 battery. It is ideal for outdoor and indoor usage. It can hold its power for more than eight years.

Conclusion

Because the button-shaped batteries aren’t chargeable, you’ll always have to replace them with new ones to continue with the functionality of your electronic device.

Fortunately, this article compares the different variations and brands available in the market. It is advisable to go for well-known brands to ensure you get a quality product. It also ensures that your device doesn’t get damaged.

In addition, using this information will help you decide exactly the kind of battery you’ll need for your device.
