Features

Compact Size and Lightweight Design

With a diameter of 16mm and a thickness of 2.0mm, the CR1620 battery has a coin-like design. Due to its compact size, these devices can be used in wristwatches, key fobs, hearing aids, and small medical devices. With the CR1620, power delivery is not compromised despite its size, making it a value-for-money battery for applications that need a lightweight yet reliable power source without compromising performance.

Long Shelf Life

In addition to its extended shelf life, the CR1620 battery can be stored properly for up to 10 years. The lithium battery technology has a low self-discharge rate. In addition to retaining its charge for a long period of time, the CR1620 keeps its readiness for use even when not in use. Batteries may sit unused for long periods of time, but retain power if they are activated. This feature is particularly helpful for spare key fobs or remote controls.

Stable Voltage Output

For devices that require stable voltage for reliable performance, the CR1620 provides a constant 3V output throughout its lifetime. Medical devices, watches, and thermometers, all of which rely on a stable output, are sensitive electronics that are susceptible to inaccurate readings or malfunctions caused by fluctuating voltage. Lithium chemistry in the CR1620 delivers reliable power until the battery runs out, thanks to its narrow voltage range.

High Energy Density

Comparing the CR1620 with other types of batteries, it has a relatively high energy density. As a result, it is suitable for devices in limited spaces that need long-lasting power, since it can store a substantial amount of energy in a compact form. The CR1620's high energy density makes it ideal for devices with lower power requirements, such as wristwatches, calculators, and remote controls, since it can be used for extended periods of time before requiring replacement.

Wide Temperature Range

In most cases, the CR1620 battery can operate between -20°C and +60°C with excellent performance. It can be used in both hot and cold environments without significantly degrading performance due to its temperature tolerance. It can withstand extreme temperature changes and still deliver consistent performance whether it is used in outdoor devices or medical equipment.

Leakage Resistance

There is a high resistance to leakage in lithium batteries, including the CR1620, even when they are stored for long periods of time. In comparison to other battery types, such as alkaline batteries, which leak more over time, lithium batteries are a safer option. By using the CR1620, you can be confident that your device will not be damaged by battery acids or chemicals leaking from the battery. Devices with sensitive components are particularly sensitive to leaks, as corrosive leaks can cause malfunctions and corrosion.

Low Self-Discharge Rate

It typically self-discharges around 1-2% per year, which is very low for a CR1620. This means the battery won't lose much of its charge even if left unused for a long time. By reducing self-discharge rates, the CR1620 provides longer power to devices, reducing the chance of batteries needing to be replaced frequently. This is particularly beneficial for emergency devices and backup systems where the battery will be used occasionally.

Eco-Friendly and Non-Toxic

Comparatively to other types of batteries, such as mercury- and cadmium-containing batteries, lithium batteries, such as the CR1620, are considered more environmentally friendly. In terms of environmental impact, lithium batteries such as the CR1620 pose fewer risks because of their composition. A safety concern in home and consumer products would be accidental ingestion or exposure to the CR1620 battery, such as in medical devices or toys for children.

Wide Availability and Compatibility

There are many devices that are compatible with the CR1620 battery, which is widely available. Replacement batteries for this type of battery are readily available since it is widely used in consumer electronics. In addition to its widespread use in a variety of devices, the CR1620 is also available both online and in retail stores. A number of devices from a variety of manufacturers can be seamlessly integrated without the need for specialized components.

Cost-Effective

The CR1620 battery is relatively inexpensive because it is widely used and manufactured efficiently. Especially in devices requiring frequent battery replacements but not requiring expensive solutions, its cost-effectiveness makes it an attractive option.
