CR2430 vs CR2450: Is there any differences between them?

CR2430 batteries are non-rechargeable Lithium Manganese Dioxide (LiMnO2) button/coin-cell batteries, featuring physical dimensions of (D x H) 24.5 x 3.0 mm (~0.9646 x 0.1181 inches).

CR2430 batteries feature a nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and a nominal capacity of ~270-320 mAh - as usual with the batteries, actual capacity depends on the battery age, storage temperature, drain conditions (current, temperature), and similar.

The standard discharge current of CR2430 batteries is ~0.2 mA, while the pulse current depends on the pulse length, but generally, it is in the 7-15 mA range.

CR2450 is commonly used in watches, computer motherboards, medical devices, LED flashlights, toys, remote controls, remote car keys, security systems, wearable electronics, etc.

Compared to smaller 3.0V lithium batteries, the CR2450 is a large and powerful battery with a large capacity and is often used in 'high' drain devices.

The CR2450 battery has a diameter of 24 mm (~0.945 inches) and a height of 5.0 mm (~0.197 inches) and a weight range of 5.7-6.3+ grams (0.2-0.222+ ounces).

The CR2450 battery has a negative electrode made of lithium and a positive electrode made of manganese dioxide, so its label starts with 'CR.'

The standard label for the 2450 manganese-dioxide positive electrode lithium battery is CR2450, although other labels are also used, such as 5029LC, DL2450, ECR2450, CR2450N, CR-2450, CR2450EL, CR-2450EL, CR-2450EL, etc. 

CR2430 Applications

The Lithium Coin CR2430 has several proven achievements for appliances where traditional batteries cannot be used. These can be used for calculators, digital watches, car keys, laser pens, fitness appliances, and medical devices like a tensiometer and a clinical thermometers.

CR2450 Applications

The Lithium Coin CR2450 batteries have certain accomplishments for applications where traditional batteries cannot be used. Use them for calculators, digital watches, laser pens, car keys, medical devices like a clinical thermometer and a tensiometer, and fitness appliances.

CR2430 Features

• Can be used in a wide range of temperatures (-30°C to +70°C)

• Lightweight, High Voltage, and High Energy Density

The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space-saving and weight reduction.

No mercury added

• A full lineup for use in a wide variety of applications

• Long shelf life: up to 10 years

Leave the Panasonic lithium coin CR2430 batteries for 10 years in storage and they still have 90% of their original capacity. This is the result of the chemical stability due to the combination of manganese and lithium dioxide. This long-term discharge has been tested at all operating temperatures under low-load discharge conditions.

• Lots of power in a compact design

The lithium coin CR2430 battery is provided with lots of power (3V) in an ultra-compact design. When you need two, three, or more traditional batteries, you will only need one single lithium battery. This battery is excellent for small devices that require lots of power.

• Excellent Leakage Resistance

The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time.

CR2450 Features

• Lightweight, High Voltage, and High Energy Density

The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space-saving and weight reduction.

• Excellent Discharge Characteristics

Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required).

• Excellent Leakage Resistance

The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time.

• Usable in a wide range of temperatures (-30°C to +60°C)

• Very low self-discharge; long shelf life of up to 10 years

• A full lineup for use in a wide variety of applications

• The very high weight-to-power ratio

• No mercury added

The CR2430 battery is also a replacement for equivalent batteries:

CR2430, DL2430, BR2430, KL2430, L2430, ECR2430, 5011LC, L20, KCR2430, E-CR2430, KECR2430, LF1/2W

CR2450 battery can be replaced by DL2450.

CR2450 Dimensions

CR2450 is commonly used in watches, computer motherboards, medical devices, LED flashlights, toys, remote controls, remote car keys, security systems, wearable electronics, etc.

Compared to smaller 3.0V lithium batteries, the CR2450 is a large and powerful battery with a large capacity and is often used in 'high' drain devices.

The CR2450 battery has a diameter of 24 mm (~0.945 inches) and a height of 5.0 mm (~0.197 inches) and a weight range of 5.7-6.3+ grams (0.2-0.222+ ounces).

The CR2430 battery is a non-rechargeable lithium 3.0-volt battery with a typical capacity of 270-300 mAh and dimensions of 24.5 x 3.0 mm.

As can be seen, the CR2430 battery may fit into the battery compartments designed for CR2450  batteries, but contacts may cause problems. Furthermore, the CR2430 has much lower capacity and drain currents, which may cause certain devices to malfunction.

To summarize, do not replace the CR2450  battery with the CR2430 battery unless absolutely necessary and at your own risk!

Modern CR2430 batteries don't contain mercury, cadmium, lead, and other heavy and toxic metals.

However, if the CR2430 or any other similar battery gets swallowed by kids or pets, body fluids short-circuit the battery causing various electrolytic processes that are very dangerous, even lethal - that is why most CR and similar batteries come in 'child-proof' and similar packages.

Although CR2430 batteries are not small, this may happen - if it happens, contact the nearest emergency center ASAP and do as instructed.

Please, this is a serious warning and should be treated as such!
