CR2450 VS LIR2450[FAQ+Video]: Are they interchangeable?

CR2450 is a 3V Coin Cell Battery by Panasonic which delivers consistent and long-lasting power. It’s made of Lithium Manganese Dioxide (LiMnO2) and is ultra-compact in design. It has a capacity 620mAh and it’s not rechargeable. It’s one of the CR series of batteries of Panasonic. The CR series of Panasonic coin battery capacity ranges from 25mAh to 1000mAh.

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 a little over 100 mA/Hour capacity, with nominal 3.6 V output. This battery is perfect for powering a small project.

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.

LIR2450 Features

Long Cycle Life: Under normal usage, the cycle life of the LIR2450 Lithium-Ion battery can be ≥500 circles while with a capacity of≥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 the voltage of NI-MH or NI-CD, which reduces the quantity of the battery needed in certain applications.

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

Low self-discharge rate: ≤5%/month

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

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

     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 the CR2450 battery with a 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 are usually 10-30% per year, sometimes even more.
