CR1620 Battery Equivalents and Specifications Guide

A CR1620 lithium non-rechargeable button battery is commonly found in car keys, watches, remote controls, toys, micro-LED flashlights, CMOS and motherboard batteries, and similar items. Most major battery brands manufacture the CR1620 battery, so finding a replacement should not be a challenge.

There is, however, some confusion among users due to the different labeling used by manufacturers. Read below for full equivalent CR1620 batteries.


Specifications and features of CR1620 batteries

CR1620 batteries are small and easy to carry around. These button/coin cells feature physical dimensions of (DxH) 16mm x 2mm (~0.62992 inches), hold a nominal voltage at 3 volts, but cutoff drops down to only 2 before dying out completely with no services left for your device–unless you can find another CR-series battery!

The CR1620 battery is typically discharged at a rate of 0.1 mA, with a maximum discharge rate of 1.0 mA – these values vary slightly between manufacturers. As a result of higher discharge rates, however, the battery’s actual capacity decreases.

There are various types of CR1620 manganese-dioxide lithium batteries, varying in self-discharge rate from 1-2% per year to 1% or less depending on the model, making these batteries suitable as a memory battery in various devices. Increasing the battery temperature, however, increases the self-discharge rate.

Batteries with the dimensions 16 x 2 mm and CR1620 (IEC standard) are commonly known as CR1620 and 5009L, while other labels exist as well, such as ECR1620, DL1620, VCR1620, etc. Even so, most manufacturers apply CR1620 labels as well.

The benefits of LITHIUM COIN CR1620

  • Mercury is not added
  • Three-voltage power supply
  • Temperature range (-30°C to +60°C):
  • It has a very low self-discharge rate and up to a 10 year shelf life
  • We offer a full range of products for a wide variety of uses

Power supply that is ultra-compact:

Lithium batteries are the future. Why replace something that is still working properly when you can just upgrade with one of these babies? They’re tiny, powerful and very convenient!


The LITHIUM COIN CR1620 has proven to be a reliable alternative for appliances in which conventional batteries aren’t suitable. They can be used for calculators, digital watches, laser pens, car keys, fitness appliances, memory backups, and medical devices such as clinical thermometers and tensiometers.

Self-discharge is extremely low:

Panasonic lithium coin CR1620 batteries hold 90% of their original charge even after 10 years because they are chemically very stable. Lithium and manganese dioxide are responsible for the chemical stability. All operating temperatures were verified in low-load discharge conditions for long-term discharge.

High reliability and safety:

Panasonic has repeatedly tested the performance and safety of its Lithium Coin CR1620. Temperature and other environmental factors were also taken into consideration. In addition to short-term accelerated tests, our battery performance has been corroborated by an abundance of long-term accelerated tests. What was the result? For their high level of safety and reliability, Panasonic batteries have been approved under the UL safety standards in the United States.


Batteries: BR1620 versus LiR1620 versus ML1620 versus CR1620

It is very uncommon to find BR1620, LiR1620, or ML1620 batteries in everyday life.It features a slightly higher capacity and lower drain current than the CR1620, but also has a significantly lower discharge rate and a wider temperature range than the BR1620 battery. Battery BR1620’s nominal voltage is between 2.8 and 3.0 volts, and the cutoff voltage is between 2.25 and 2.0 volts, depending on the exact chemistry.

LiR1620 batteries are rechargeable lithium batteries that have a lower capacity than CR1620 batteries, but they can be recharged multiple times. The LiR1620 battery’s nominal voltage ranges from 3.6-3.7 volts, and some devices designed for CR1620 batteries may not support the use of the LiR1620 battery. Approximately 5% of the LiR1620 battery’s capacity is lost each month due to self-discharge.

There is a rechargeable lithium manganese dioxide battery, called the ML1620, which has a 3.0 volt nominal voltage. It can be used rather than the CR1620. However, since the battery has a lower capacity and a higher self-discharge rate, it is rarely used.

A CR1620 battery is the best choice if you are looking for a coin battery that measures 16.0 x 2.0 mm.

It has the same diameter of 16.0 mm, but it differs in height, as well as they have different drain currents and other features: The CR1616 and CR1620 are both non-rechargeable manganese-oxide lithium batteries:


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


Despite the fact that most battery compartments that can accept CR1620 batteries are also capable of accepting CR1616 batteries, CR1616 batteries are not recommended since they have a lower capacity and have more small drain/pulse current limitations that might result in malfunctions.

Issues with CR1620:

In the same way as other small, shiny objects (including other button/coin cell batteries), CR1620 batteries can be swallowed by children and pets. That’s why these batteries are packaged in ‘pet-safe’ and ‘kid-safe’ packages.


While CR1620 batteries do not contain mercury, cadmium, lead, or any other toxic heavy metals or pollutants, swallowing them can harm internal organs and cause chemical burns.


Contact your nearest emergency center (or doctor) immediately after swallowing a CR1620 battery (or any battery that is similar). Explain what happened and follow their instructions.
