Non-rechargeable lithium 3.0 volts CR2430 batteries are commonly used in watches, fitness wearable electronics, automobile keys, remote controllers, healthcare devices, backup batteries, and other applications.

Besides, the CR2430 battery equivalent can be used for a similar purpose. But sometimes, these equivalents are obtained in various chemistries, leading to misunderstandings among users. They often ask, “What battery can replace CR2430?So to clear the doubt, here we briefly discuss different features, equivalents and replacements of the cr2430 battery.

Usually, the CR2430 battery replaces DL2430, BR2430, KL2430, L2430, ECR2430, 5011LC L20, KECR2430, ECR2430, LF1/2W. While certain battery brands (Duracell, Energizer, etc.) employ ‘customized’ CR2430 labeling, the batteries themselves are ordinary CR2430 batteries.

CR2430 Battery Specifications 

  • Voltage: 3.0 Volts;
  • Cutoff voltage: 2.0 volts;
  • Capacity: 270 to 320 mAh;
  • Chemistry: Lithium Manganese Dioxide (LiMnO2);
  • Discharge current: ~0.2 mA;
  • Type: Non-rechargeable;
  • Dimensions: (D x H) 24.5 x 3.0 mm;
  • Operating Temperature Range:-30℃ to 70℃;
  • Shelf life: 5-10 years.

CR2430 Battery Features

The following are some of the most important characteristics of the CR2430:

High Voltage, Low Weight, and High Energy Density

Compared to typical alkaline or manganese batteries, this battery has a voltage nearly double that of 3 volts. For optimal space and weight savings, this implies halving the number of batteries needed for equipment. In addition, the discharge characteristics are excellent.

The battery’s voltage characteristics remain stable even after prolonged discharge, enhancing the battery’s overall durability. Additionally, this kind of technology does not require any type of upkeep. For example, LiCB CR2430  is a Zero Mercury, safe and compatible battery.

Better Leakage Resistance 

Improved battery construction and electrolyte ensure long-term leakage resistance. Duracell coin batteries are designed to provide leakage resistance and reliable performance over an extended period.

Long-term Reliability

The electrolyte and the active material of these batteries are made from carefully selected active ingredients. So those are questions about How long does a 2430 battery last? Now be relaxed by knowing the breakthrough technology seals these materials to reduce battery self-discharge and last longer. 

But keep in mind, one percent of the nominal capacity is lost annually to self-discharge at room temperature and average humidity. Most brands have a shelf life of 5-10 years, like Toshiba CR2430; however, as the storage temperature rises, so does the self-discharge rate.


Most of the CR2430 battery is free of mercury (Hg), cadmium (Cd), and lead (Pb) and complies with EC regulations. Also, it is free from the use of certain hazardous chemicals. But always keep these tiny batteries from children and pets, which they might swallow.

Various Compatibility

This product is equivalent to various brand models, such as the DL2430, BR2430, KL2430, ECR2430, 5011LC, L20, KCR2430, ECR2430, KECR2430, and works perfectly for remote control devices, watches, calculators, electronic notebooks, thermometers, and mobile games. 

Equivalents Batteries of CR2430 Battery

Those who want to know what battery is the same as CR2430 can be knowledgeable enough after reading the features of each category below:


The BR2430 batteries have a size of 24.5 x 3.0 mm and use Lithium Carbon Monofluoride chemistry, and they are non-rechargeable. The BR2430 battery has a nominal voltage of 3.0 volts (earlier batteries had 2.8 volts), a cutoff voltage of 2.0 to 2.25 volts, and a capacity slightly less than the CR2430.

They also discharge at a lower current than CR2430 batteries. TIANQIU 5 X Br2430 batteries have a low self-discharge rate, a 10-year shelf life, and a wider temperature range. BR2430 batteries are utilized in low draw devices such as memory backup and CMOS batteries.


The ML2430 are rechargeable batteries. They have a lithium manganese oxide positive electrode and a lithium aluminum alloy negative electrode. ML2430 battery has a 3.0-volt nominal voltage, 2.5-volt average discharge voltage, 2.0-volt cutoff, and 3.2-volt charge voltage.

A typical capacity of 100 mAh, a maximum continuous discharge current of 10 mA, and a maximum pulse current of 20 mA are all features of the ML2430 battery. It can sustain many hundred charging or discharging cycles. It has the same voltage as CR2430 batteries but a higher self-discharge rate. The gadgets that use ML2430 batteries generally have built-in battery chargers; therefore, charging a CR2430 battery can be risky.

The LiR2430 battery uses lithium-ion chemistry and has a nominal voltage between 3.2 and 3.7 volts. The nominal capacity is 90 to 100 mAh with a 20 mA maximum continuous discharge current (0.2C). Besides, the charging voltage for 3.6 to 3.7V batteries should be 4.2 volts or a little lower.

If appropriately used, LiR2430 batteries can withstand 300 to 500 charging or discharging cycles even when nearly drained. Hillflower LIR2430 is one of them. The voltage difference between CR2430 and LiR2430 batteries is small, yet it might cause specific devices to malfunction or even damage sensitive electronics.

DL2430 and KL2430

The DL2430 and KL2430, 3 Volt lithium coin battery is the equivalent of CR2430, and it comes with a high life span. Devices such as heart-rate monitors, keyless access, glucose monitors, games, and toys use these batteries for consistent performance. Besides, these types of batteries have a storage life of 8 years. The most popular Murata DL2430 exemplifies Japan’s long tradition of producing high-performance, dependable micro-batteries.


These batteries are commonly used in watches, sensors, and calculators like CR2430 because they easily fit into small battery compartments. When comparing batteries of similar size, look at their capacity in milliampere-hours, and more mA-hr means more battery life. Skoanbe ECR2430  lithium batteries are the lightest and longest-lasting button cells.


It’s hard to beat the 5011LC, a replacement battery of CR2430 when it comes to 3v lithium coin cell batteries since it gives you the power you need when you need it. The 

Eunicell 5011LC is constructed with just the highest-quality materials to ensure its durability, and they are particularly well suited for products that require a reliable power source, such as remote controls and wristwatches, among others.

What to Look for When You Buy CR2430 and Equivalents

When making a decision, it’s essential to consider the product’s technical specifications. The higher they are compared to other models, the better off they are. Below are the factors that should keep in mind while purchasing:

  • Capacity rating;
  • New product’s voltage;
  • The temperature of work;
  • Casing material (corrosion-resistant types are preferable);
  • A galvanic cell’s property;
  • The voltage energy density should not be less than 3v;
  • Use and storage timeframes.

The country where it was made doesn’t play a significant role in which is better. So you can buy high-quality products made in China, the United States, and other countries as well.
