Basics of CR1620 Battery- Equivalent, Voltage, & Uses

Last updated on April 2nd, 2024 at 11:53 am

It is a lightweight primary lithium coin battery with a nominal voltage of 3V, a typical capacity of 80 mAh, weighs 1.3 g, and is 16 mm in diameter and 2.0 mm in height. It has a shelf life of 5-10 years when stored at room temperature.

This battery is generally used in products such as car keys, remote controls, micro flashlights, digital watches, credit card-sized devices, etc, and does not contain mercury, cadmium, lead, or any other harmful heavy metals or pollutants.

CR1620 stands for?

CR1620 stands for a lithium manganese dioxide battery (round shape) having a 16 mm diameter and 2 mm thickness.

  • The letter C indicates the chemical composition used in the battery (here ie, Lithium Manganese Dioxide)
  • The letter R indicates the shape of the battery (here ie, Round)
  • The first two digits indicate the battery’s diameter in millimeters (here ie. 16mm)
  • The second two digits indicate the battery’s thickness (here ie. 20mm)

Given below are some batteries that can be replaced with CR1620.

  • BR1620
  • ML1620
  • ECR1620
  • DL1620
  • VCR1620
  • KCR1620
  • KECR1620
  • KL1620
  • L1620

Here, it is evident that only the alphabets are different. The last four numerals are the same. Hence all these equivalents are replaceable with CR1632 but they differ in performance.

Note: The other chemistries may not offer the same features as the lithium-manganese dioxide chemistry. So it is necessary to verify the device’s power requirements before using an equivalent.

Can CR1620 be replaced with CR1632?

The batteries are of different heights. CR1632 is 3.2 mm thick while CR1620 is 2.0 mm thick. Though they have the same output voltage, some mechanical adjustments are required to use them interchangeably.

Are CR1620 batteries dangerous?

No, these batteries don’t contain mercury, cadmium, lead, or any other toxic heavy metals and similar pollutants, but dangerous when swallowed – they can cause chemical burns and physical damage to internal organs.

What are the benefits of CR1620 batteries?

1. Lightweight, High Voltage, and High Energy Density
2. Very low self-discharge rate, hence long shelf life up to 10 years
3. Excellent Leakage Resistance
4. Excellent Long-Term Reliability
5. High safety
