CR1620 Battery Overview
The CR1620 battery is a small coin cell battery that is commonly used in a variety of small electronic devices. The CR1620 is a 3-volt lithium coin cell battery whose chemistry is lithium manganese dioxide. The "CR" in the CR1620 name indicates that it is a lithium manganese dioxide battery, and the number "1620" indicates its size: approximately 16 mm in diameter and approximately 2.0 mm in height. Its small size and stable voltage output make it suitable for use in devices such as watches, calculators, and car remote control keys.
CR1620 Lithium Battery
An important aspect of the CR1620 battery is that it is not rechargeable. This means that once the battery is exhausted, it must be replaced, not recharged.

CR1620 Battery Equivalent
CR1620 battery is a commonly used 3-volt lithium button battery. The equivalent batteries of CR1620 battery include: BR1620, LiR1620, ML1620, DL1620. Before using these batteries as CR1620 battery replacements, it is important to consider the voltage rating and chemistry of the equivalent battery. Below is information on these equivalent battery parameters:
BR1620 Battery
Chemistry: Lithium poly-carbon monofluoride
Voltage: Nominal voltage between 2.8 and 3.0 volts, with a cutoff voltage ranging from 2.25 to 2.0 volts depending on the chemistry.
Characteristics: Offers higher voltage stability under various temperature conditions, making it suitable for devices used in diverse environments. It has a slightly higher capacity and lower drain current compared to the CR1620 but features a significantly lower discharge rate.
LiR1620 Battery
Chemistry: Rechargeable lithium-ion
Voltage: Nominal voltage ranges from 3.6-3.7 volts.
Characteristics: Although it has a lower capacity than the CR1620, the LiR1620 can be recharged multiple times, making it potentially more cost-effective for long-term use. However, about 5% of its capacity is lost each month due to self-discharge, and some devices designed for CR1620 may not support this higher voltage.
ML1620 Battery
Chemistry: Rechargeable lithium manganese dioxide
Voltage: Nominal voltage of 3.0 volts.
Characteristics: Similar to the LiR1620 in terms of rechargeability but generally has a lower capacity and a higher self-discharge rate. It is less commonly used due to these limitations.
Application
CR1620 3 volt battery is commonly used in Remote keyless entry, Card remote controls, memory backup, security price tags, smart transmitter tags and others.
CR1616 vs CR1620 Battery
CR1616 vs CR1620: Dimensions
CR1616(left) and CR1620(right) dimension
Both batteries share the same diameter of 16.0 mm. The CR1616 is thinner with a height of 1.6 mm, while the CR1620 is thicker at 2.0 mm.
CR1620 vs CR1616: Capacity
The CR1616 has a capacity range of 50-55 mAh, whereas the CR1620 offers a higher capacity range of 65-80 mAh. This higher capacity allows the CR1620 to deliver more energy over its lifetime, making it suitable for devices that consume more power or require longer battery life.
CR1620 vs CR1616: Compatibility and Usage
Although most battery cases that can accept CR1620 batteries will also accept CR1616 batteries, CR1616 batteries are not recommended due to their lower capacity and smaller draw/pulse current limit, which may cause failure.
FAQ
1. Is a CR1620 battery the same as CR2016?
No, a CR1620 battery is not the same as a CR2016. While both are 3V lithium coin cells, the CR1620 is slightly thicker (2.0 mm vs. 1.6 mm) and generally has a higher capacity, making them not directly interchangeable without considering device compatibility.
2. Are 1620 and 1632 batteries the same?
No, 1620 (CR1620) and 1632 (CR1632) batteries are not the same. The CR1632 is thicker (3.2 mm) compared to the CR1620 (2.0 mm), which affects both the physical fit in a device and the electrical capacity.
3. What is the difference between CR1632 and CR1620 battery?
The main difference between CR1632 and CR1620 batteries lies in their thickness and capacity. The CR1632 is thicker (3.2 mm vs. 2.0 mm for the CR1620) and typically has a higher capacity, which translates to longer battery life under similar usage conditions.
4. What is the difference between CR2025 and CR1620 battery?
The CR2025 and CR1620 batteries differ primarily in size and capacity. The CR2025 is thicker (2.5 mm vs. 2.0 mm for the CR1620) and usually has a higher capacity.
5. What battery can replace CR2016?
BR1620, LiR1620, ML1620, and DL1620 batteries can be used to replace CR1620 batteries. These batteries are the same dimensions as the CR1620 battery.
