CR2430 Description

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, cutoff voltage of 2.0 volts, and 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 pulse current depends on the pulse length, but generally, it is in the 7-15 mA range.


CR2430 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.

 

  • Excellent Long-Term Reliability

Carefully selected active materials are used for the active material as well as for the electrolyte. These materials are sealed by

Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal

humidity is less than 1% of the nominal capacity.

 

  • UL Approved Parts

Murata's Coin Manganese Dioxide Lithium Batteries are approved by UL. (UL1642 File No. MH12566)

 

  • RoHS Directive / European Directives

This product does not contain Mercury(Hg), Cadmium(Cd), nor Lead(Pb), and conforms to EC regulation values. (Directive

2006/66/EC, 2013/56/EU) Battery pack are excluded from RoHS directive (DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 8 June 2011 on the restriction of the use of certain

What are Coin Batteries

coin batteries

coin batteries

Coin batteries, commonly known as button cells. A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high — resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell. An insulated top cap is the negative terminal.

 

Coin batteries are commonly used in garage door openers, medical devices, watches, remote controls and greeting cards with sound. Do not leave these devices readily available and make sure children are supervised when in contact with them so that access to coin batteries can be prevented.


CR2430 Equivalent

The CR2430 battery is also a replacement for equivalent batteries:

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


CR2430 vs CR2450

CR2450

CR2450

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!

FAQ

  • Are CR2450 and CR2430 interchangeable?

Non-rechargeable 3.0 volts lithium CR2430CR2450, CR2477 batteries feature the same diameter of 24 mm (~0.945 inches), but different height of 3.0, 5.0 and 7.7 mm (~0.118, 0.197 and 0.303 inches) respectively.

  • What are 2430 batteries used for?

They are popular because they deliver Ideal Temperature Resistance and Superior Storage capacity. CR2430 Lithiums in particular are commonly used in the following applications: Watches, Pagers, Calculators, PDA Organizers (electronic agendas), lights and other electronic devices.

  • Is DL2430 same as CR2430?

Duracell DL2430 batteries are fully interchangeable with all CR2430 batteries.

  • What battery is equivalent to CR2430?

CR2025 and CR2032 batteries can sometimes be used in place of each other, even though CR2025 batteries are slightly thinner. There is no true substitute for a CR2430 battery, and they represent a somewhat unique size in the battery world.
