cr2025 vs cr2032

Introduction

The modern automobile industry is developing very rapidly. Take car keys for example, the traditional mechanical keys are basically replaced now. Because our remote control keys and even smart keys are already very common. However, this also brings some troubles to many consumers-what should I do if the key is out of power or the battery is damaged? How to replace the battery? What type of battery should I choose?
For example, in most cases, temperatures too high or too low still compromise their ability to store and release energy. Put simply, cold weather will decrease the lifespan of your battery because it will require charging more often. Here will give you some basic ideas of car key batteries comparison in modern life.

Ⅰ What Are CR Batteries?

1.1 CR×××× Definition

Generally speaking, the batteries of car keys are button batteries, which have a relatively long service life. Conventionally, a battery can be used for more than 3 years. To replace the battery of the car key, you must buy the right model. Not all car keys use CR2032, while CR2450, CR2025, and CR2016 are also optional. Here, what models are CR2032 and CR2025? What does CR stand for in battery? According to IEC rules, in Lithium batteries, Chromium is also used in it that is why it's also called CR batteries. Most of the people related CR with the button or coin batteries but it's a chemical designation of Chromium.
C-denotes Lithium Manganese Dioxide.
R-after another letter denotes a round cell with the chemistry shown by the first letter.
Digit-The next four digits indicate the size, the first two digits indicate the diameter, and the last two digits indicate the thickness.
All the batteries who have this chemical substance in their batteries they can use this abbreviation CR.

They are not rechargeable, and are all lithium primary batteries. That is, they are very similar to each other. The shelf life of lithium coin cells stored at normal room temperature and relative humidity is 10 years. If the manufacturing level is not high or the quality control is not good, their life will be greatly shortened. What’s more, if the use environment is ideal, their life span can reach 10 years or more. They are often used on computer motherboard CMOS batteries, memory functions or power-off protection modules, electronic scales, calculators, electronic dictionaries and other products, and can also be used on car remote control keys. With the requirements of new industries, there are also specially improved with very different capacities, mainly to improve their high-current output capabilities, such as those used in flashing lights or RF products.
From the above, we can see the difference between them. As for interchangeable batteries, if you are a consumer, replace the battery with the same one that was originally intended, as the holder was designed to fit either one or the other.
A derivative problem, what happens to old lithium batteries? Since they cannot be recharged, they has to be disposed of properly. For proper disposal of large numbers of lithium batteries at the same time, they can be disposed of by scattering them in different directions so that they will not touch one another. In short, you can't throw away lithium-ion batteries with your regular trash or even in your blue recycling bin. What you should do is dropping them off at a battery recycling center or battery drop-off, or requesting a battery pick-up through your local government's website.

 

Frequently Asked Questions about Difference between Cr2032 and CR2025, CR2016, CR2450

1. Can I replace a CR2016 battery with a CR2032?
They are not the same in thickness, the cr2016 is thinner then the cr2032 although if you stack two of the cr2016 batteries then it will then be the same thickness as the cr2032 battery and they both worked for the car stereo remote and key fob. That is, if it fits in the device's battery slot and makes a good electrical connection, a CR2016 can substitute for a CR2032. However, it will have less than half the CR2032's lifetime.

 

2. Can I use a CR2032 in place of a CR2025?
2032 and 2025 are literally the dimensions of the battery. For as long as either fits in the battery compartment, the CR2025 and CR2032 may be used interchangeably with minimal effect although the CR2032 would probably last slightly longer simply because it has a higher capacity (mAh).

 

3. Are CR1632 and CR2032 interchangeable?
The CR1632 battery is very similar to CR2032 or CR2025 but they are not interchangeable because of their dimensions. The name CR1632 indicates that the battery is 16mm wide and 3.2mm thick. It is rated for 3V and 130mAh capacity.

 

4. Is CR2450 the same as CR2032?
CR2450 vs CR2032
CR2450 is often compared with a very popular lithium 3.0 volts CR2032 battery. Output voltages of these batteries are the same for the same chemistry types. However, due to the larger volume of CR2450, it features a larger capacity - 600-620 mAh (CR2450) vs 210-230 mAh (CR2032).
