This article focuses on two commonly used coin cells: CR2430 and CR2032. What sets them apart? How do they compare in terms of compatibility? We will uncover these aspects one by one. We can't overlook their physical characteristics, capacity, voltage, and chemical composition. Additionally, we'll explore their applications in everyday electronic devices and discuss their respective strengths and limitations.
CR2430 and CR2032, while both coin cells, have significant differences. Understanding these distinctions can help you choose the most suitable battery for your device. Let's delve deeper and thoroughly comprehend the unique aspects of these two types of batteries.
What is CR2430 battery ?
CR2430 coin cells, measuring 24.5mm in diameter and 5.0mm in height, are non-rechargeable lithium batteries. They boast a notable shelf life, simplifying storage. With a 300mAh capacity, these batteries operate efficiently in a wide temperature range, from a frosty -30 to a sweltering +60 degrees Celsius.
Ideal for a variety of brands, these batteries power cameras, calculators, and other handheld devices that require this specific size. They outperform equivalent zinc battery models in power. Their impressive shelf life, extending up to 10 years, enables users to maintain a steady supply, worry-free.
Benefits of CR2430 Batteries
Wide Temperature Operating Range: Usable across a broad temperature spectrum, from -30°C to +60°C.
Longevity: With extremely low self-discharge, they typically have a long shelf life and operational duration, hence requiring less frequent replacement.
High Voltage: The CR2430 has a nominal voltage of 3 volts and a cut-off charging voltage of 2.0 volts. The 3-volt power in a single battery is roughly double that of traditional dry cells.
Free of Harmful Metals: Lithium batteries generally do not contain hazardous metals such as mercury, cadmium, and lead.
Practicality: In addition to being suitable for a wide range of everyday applications, they can also be used under various environmental conditions, including high humidity and in high-altitude regions.

CR2430 Equivalent
Equivalent battery models related to the CR2430 lithium battery include: DL2430, ECR2430, KCR2430, KECR2430, BR2430, KL2430, LM2430, ML2430, 5011LC, and LF1/2W batteries.
It's important to note that lithium batteries come in various shapes, sizes, and capacities. When replacing a battery, be sure to confirm the battery model, chemical composition, and crucial specifications like capacity and current. Also, check the manufacturer's recommendations for replacement.
CR2430 VS CR2032
The physical differences between CR2430 and CR2032 batteries are quite pronounced. The CR2430 has a diameter of 24mm and a thickness of 3.0mm; in contrast, the CR2032 measures 20mm in diameter and 3.2mm in thickness. Although the CR2430 is larger, this doesn’t necessarily translate to higher capacity or longer life.
When it comes to choosing a battery, capacity and voltage are key. The CR2430 boasts a capacity of 270mAh, surpassing the 220mAh of the CR2032; more capacity means a longer lifespan. However, higher capacity often comes with higher voltage, which may not be suitable for some devices. The CR2430 has a voltage of 3V, whereas the CR2032 is rated at 2.8V.
Their chemical compositions also differ. The CR2032 is made of lithium and manganese dioxide, while the CR2430 is a lithium-manganese dioxide battery. Although both are suitable for high and low drain devices, the chemical composition of the CR2430 might offer a longer lifespan in the right devices.
When selecting a battery, it’s crucial to consider the manufacturer's recommendations. Using a battery with too high a voltage can damage the device, and one with too low a capacity may need frequent replacement, leading to higher long-term costs.
Battery CR2430 Size
The compact CR2430 battery measures 24.5mm in diameter with a height of 3.0mm. It has a typical weight and volume of 4.6 grams (0.16 oz) and 1.3 cubic centimetres (0.08 cubic inches) respectively.
The standard lithium content of the CR2430 is less than 0.3g.
What to look for when buying the CR2430 and equivalents
When making a decision, it is important to consider the technical specifications of the product. The higher they are compared to other models, the better they are. The following are the factors that should be kept in mind while making a purchase:
- Rated capacity.
- Voltage of new products; and
- Operating temperature; and
- Shell material (corrosion-resistant type is preferred).
- Characteristics of Primary Battery
- Voltage energy density should be not less than 3v.
- Use and storage time range.
