Basis Of The CR2450 Batteries 

CR2450 batteries are more powerful, large, and non-rechargeable coin cell or button batteries. CR2450 is used in multiple devices such as remote control, computer motherboards, medical devices, LED flashlights, toys, car remote keys, watches, security systems, and wearable electronics. Sometimes this kind of battery works in high-drain gadgets. Its capacity is also better than the smaller 3.0V lithium battery. 

CR2450 Battery Features and Specifications

CR2450 battery comes with many outstanding features. It has a diameter of ~0.945 inches and a height of ~0.197 inches. Plus, the nominal capacity is higher than other batteries, around 620mAh, although some older CR2450 models feature 540-580 mAh capacity. These models are specifically aimed at high-drain utensils. 

The negative electrode of the CR2450 battery is made up of lithium as well as the positive electrode is made up of manganese dioxide. The CR2450 battery has a label starting at ‘CR’.

The CR2450N battery is also a replacement for equivalent batteries such as CR2450N, DL2450, ECR2450, BR2450, BR2450-1W, CR2450N, KCR2450, LM2450, and 5029LC.

CR2450 Vs. BR2450: Which One’s Better?

There are some basic differences between CR2450 and BR2450 batteries. Guess what? 

Don’t panic. We share here a comparison diagram to present the most important comparisons.

Definition CR2450 battery BR2450
Labels of the batteryStart with ‘CR’The label starts with ‘BR’
Positive electrodesIt has a manganese-dioxide-positive electrode.BR2450 battery positive electrode made of carbon-monofluoride.
Advantages The major advantage is to provide the high discharge currents, necessary for keyless entry systems, remote controls, and similar devices.The main advantages are long shelf life, very low self-discharge rate, constant output voltage, and much more.
Nominal CapacityCR2450 batteries feature a capacity of around 600 to 620 mAh.The nominal capacity of the BR2450 batteries are around 500-550 mAh.
Shelf LifeFrom 3 years to more than 10 years is the shelf life of the CR2450 batteries. Only some cheaper models offer 3 years of shelf life.The most common BR2450 batteries have up to 10 years of shelf life.
Available or not available This CR2450 battery is easy to collect. This type of battery is rare because of the advances in technology. 
ReplacementSome CR2450 models can be used as an alternative for the BR2450 battery. BR2450 models can not be utilized as a replacement for CR2450 because BR2450 batteries are extremely tough to get these days.

Which One’s Better?

Though both models are good for use on multiple devices, CR2450 is available as a combination of the two of them. Sometimes you notice that a few companies label their CR2450 as BR2450 too. If you want to get both features, you should check the specific shelf-life of that CR2450 battery.

Is LiR2450 the same as CR2450? 

LiR2450 and CR2450 batteries have some similarities and differences. And, few LiR2450 models can be used as a direct replacement for CR2450 batteries. 

However,  LiR2450 is one of the types of 2450 rechargeable batteries. The most exceptional characteristic is that the LiR2450 battery has various nominal voltages like 3.0, 3.2, 3.6, and 3.7 volts.

Among those, the 3.0V rechargeable LiR2450 battery comes with a similar feature to the CR2450 battery. Essentially, both have the same output voltage, 3.0 volts. It allows you to replace these. Even there is no risk for the delicate electronics. 

Where 3.2 volts rechargeable LiR2450 batteries are made from Lithium Iron Phosphate chemistry. The main difference is its 0.2 volts excess output voltage. 

3.6V and 3.7V rechargeable LiR2450 batteries feature higher voltage than the typical CR2450 batteries. Other features are quite similar to both. But, before replacing you should check the manual.

What’s the difference between LiR2450 and CR2450 batteries? See the comparison chart to understand clearly.

Self-discharge rateThe great quality CR2450 battery self-discharge rate is  ~1% annuallyThese batteries have a higher self-discharge rate, 1-5% per month so higher than CR2450
Diameter 24.5mm x 5.0mm 24.5mm x 5.0mm

CR2430 vs. CR2450 vs. CR2477

Only the CR2430 batteries are a lower nominal capacity, just 270-290 mAh. Where CR2477 comes with the highest nominal capacity of ~1000 mAh. On the other hand, CR2450 has a higher from 600 to 620 mAh nominal capacity. This is the major difference between those. 

The diameter of 24mm or ~0.945 inches is the same as all batteries and they are Non-rechargeable 3.0 volts lithium batteries. Another difference is their height, while CR2430 is 3.0 mm ( ~0.118 inches) height. You know, CR2450 has 5.0 mm. The CR2477 comes with a larger height such as 7.7 mm.

From all three models,  the CR2477 batteries provide you with the highest performance and reliability. But, CR2450 is also good for its overall features.
