LiR2450 vs CR2450 Features Comparison

LiR2450 Features

  • Long Cycle Life: Under normal usage, the cycle life of the LIR2450 Lithium ion battery can be ≥500 circles while with capacity ≥80%.

 

  • High Power Density: High power density makes the LIR2450 battery light in weight and small in dimension. It can be used in small devices.

 

  • Safe and Reliable: No floating metal lithium assures a safer usage.

 

  • High working voltage: Working voltage is up to 3.6V, approx. 3 times of the voltage of NI-MH or NI-CD, which reduces the quantity of the battery needed in certain application.

 

  • No memory effect: No memory effect assures a constant maximum application.

 

  • Low self-discharge rate: ≤5%/month

Good consistency is showed in LIR 2450 battery capacity, internal resistance, discharge platform and capacity retention. A strict complete internal quality control is subject to the ISO9000 system

 

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.

 

  • 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 hazardous substances in electrical and electronic equipment).

Differences between LiR2450 vs CR2450 

The main differences between CR2450 and LiR2450 batteries in the voltage, capacity, and of course, rechargeable feature.

 

Voltage difference - due to the voltage difference of ~0.6-0.7 volts, not all devices powered by the CR2450 battery will operate properly when powered by the LiR2450 battery. Actually, this voltage difference may even damage some more sensitive units.

 

Thus, unless the Owner's Guide of the device you have lists 3.6-3.7V LiR2450 batteries as supported battery type, do NOT replace CR2450 battery with LiR2450 battery.

 

Capacity difference - CR2450 battery features a much larger capacity than the LiR2450 battery. But, the LiR2450 battery may be recharged up to 500-1000 times, which is a lot.

 

Note: When charging LiR2450 batteries, be sure to use battery chargers specifically intended for such batteries.

 

Also, LiR2450 batteries feature a much larger self-discharge rate than CR2450 batteries, and is usually 10-30% per year, sometimes even more.

 

LiR2450 vs CR2450 Interchangeability

LiR2450 is a typical label for rechargeable 2450 batteries. Depending on the exact chemistry used, the LiR2450 battery typically features nominal voltages of 3.0, 3.2, 3.6, and 3.7 volts.

 

3.0V rechargeable LiR2450 batteries can be used as a direct replacement for CR2450 batteries since they feature the same (similar) output voltage that never exceeds 3.0 volts and pose no threat for sensitive electronics.

 

3.2V rechargeable LiR2450 batteries are commonly based on the Lithium Iron Phosphate (LiFePO4) chemistry and although they feature only 0.2 volts larger output voltage, some sensitive electronics may have issues because of that - before using 3.2V LiR2450 batteries in such devices, check the manual of your device.

 

3.6 - 3.7V rechargeable LiR2450 batteries are based on other lithium-ion chemistries and since they feature 0.6-0.7V higher voltage than standard CR2450, before using them in your devices, be sure to check the manual - such difference is large enough to easily damage sensitive electronics or to make device unreliable. Unreliable operation is not recommended, especially not for medical and security devices - better safe than sorry.

 

On the other hand, the typical capacity of the LiR2450 is in the 100-125 mAh range and can be recharged 500-800 times.

 

Although rechargeable LiR2450 batteries feature a higher self-discharge rate (1-5% per month, compared with ~1% annually self-discharge rate of high quality CR2450 batteries), in devices that require plenty of energy on a daily basis, LiR2450 batteries can save some money.

 

Note: Never, but really never charge LiR2450 batteries with the chargers other than those recommended by their manufacturers!

Using Warnings

(1) Keep away from children. If swallowed, promptly see doctor.

(2) Do not install backwards, charge, put in fire, or mix with used or other battery types - may explode or leak causing injury. Replace all batteries at the same time.

 

LiR2450 vs CR2450 FAQ

Is LIR2450 the same as CR2450?

LIR2450 is a coin cell, Lithium-Ion rechargeable battery. Physically the same size as CR2450, LIR2450 can be used as a rechargeable replacement to CR2450 in most cases. This little battery has little over 100 mA/Hour capacity, with nominal 3.6 V output. This battery is perfect for powering a small project.

 

Are Lithium coin cell rechargeable?

Largest on the list of power's smallest tools is the lithium coin cell. They are primary Lithium, meaning these single use batteries are non rechargeable.

 

Are 2450 and 2430 batteries the same?

CR2430 coin cell batteries are known for being slightly wider than their CR2025 and CR2032 counterparts. Security sensors that use coin batteries like the CR2430 are usually small and unobtrusive. But since the CR2430 batteries are wider, they cannot be used interchangeably with CR2025 and CR2032 batteries.

 

What does CR in batteries mean?

CR is the generic designation that is used by the entire batteries maker but lithium batteries are also having chromium. All the batteries who have this chemical substance in their batteries they can use this abbreviation CR. On the other DL is the short abbreviation of the battery making company Duracell.

 

How long do lithium button batteries last?

The typical lifespan for a lithium battery is two to three years. A good rule of thumb is that once it can hold only 70-80% of its original energy storage, the battery should be replaced.
