CR2025 vs. CR2032 Batteries: What is the Difference? – ElectronicsHacks

many people have been asking the difference between a CR2025 and a CR2032. One of the foremost differences is their size, as 2025 is smaller than its successor at 3/4 column inch by 5/8 edge. The early chief dispute is that they are not interchangeable as 2025 has a contact for three volts while 2032 has one for two volts. They besides have different uses : 2025 can be used in watches, calculators, remote control controls, and toys while its predecessor can be found in cameras or smoke detectors .
In this web log post, expert electricians will discuss the difference between CR2025 and CR2032 batteries. They will go into contingent about their differences, vitamin a well as how you can use them in a assortment of situations. You may be wondering why there are two different types of these democratic batteries on the market – each with its own benefits and disadvantages. This position is going to answer all your questions !

Similarities between CR2025 vs. CR2032 Batteries

The CR2025 and CR2032 batteries are very alike in human body, size, and appearance. If you use any barrage comparison chart to compare the two types of coin cell batteries they will look about identical. The tiniest remainder is that one has an excess notch on it that makes them slightly different but not by much. You can still place either type into your device without any issues at all deoxyadenosine monophosphate long as it fits inside the compartment for your device ’ s finical lay down and model .
Both CR2025 and CR2032:

  • last up to 5 times longer than alkaline batteries;
  • are commonly found in wristwatches (and similar);
  • have expiration dates two decades later than an unused conventional coin cell would expire;
  • fit into most watch cases that were originally designed for use with disposable button cells;
  • do not contain mercury or cadmium like many old rechargeable nickel-metal hydride batteries did;
  • are not rechargeable;
  • can be obtained just about everywhere;
  • do not contain mercury/cadmium like older NiMH batteries;

Differences between CR2025 vs. CR2032 Batteries

These coin cell batteries differ in 2 chief ways, despite being very exchangeable to each other. The key difference between these two coin cell batteries is their size.
A standard CR2032 measures 20mm in diameter, while the smaller translation ’ south dimensions are 16 millimeter x 0.59 millimeter. Despite being slightly larger than its counterpart, the common form contains more energy with 185 mAh compared to merely 150 mAh on average for an Alkaline Cellular Battery of this size .
Differences between CR2025 vs. CR2032 Batteries
This means that it has more exponent output electric potential over clock time that makes it perfective for watches or calculators requiring continuous practice even when not frequently used. The lower capacity of the Lithium Cell Coin Batteries prevents them from having sufficient stream for farseeing periods but they are able to provide sufficient current for short periods .
One more difference is that the battery electric potential of a CR2032 is slightly higher than that of a CR2025 that means it will give your device just that much more office before needing to be replaced or recharged even though they are both hush considered low-power devices compared to an alkaline AA battery for example .
Another remainder is the fact that one has an extra notch on it and this makes them slenderly different but not by a lot so you can place either character into your device without any issues at all angstrom long as it fits inside its compartment for your finical take and model .

Factors to Consider When Using a CR2032 Instead of a CR2025


The CR2025 is typically used in low office applications, while the CR2032 can be found powering higher energy devices. This means that the voltage for which they are designed may change. For model, a device that functions on 12V would need to use a lithium battery of at least 2032 size quite than one using 2025 batteries because it requires more juice from its might reference .
The same goes with anything requiring fewer volts as well ; if your application needs say, merely three volts alternatively of 6-9 – you will besides want to choose 2032 over 2025. In these types of instances, you must make sure your design uses as many cells as there are required by the prefer prerequisite ( i.e., replacing two 2025 batteries with a single 2032 ) .


If you are designing an electronic device that requires high current, it is besides well to use the CR2032 battery alternatively of 2025. This is because they typically come in higher amperage ( mAh ), which means more energy can be stored using fewer batteries at a meter ; this helps make board for any extra circuitry needed for your blueprint .
When considering how many cells to use, remember that lower electric potential devices require more cells than their equivalent with a higher one. For example, if your former 12V application used two terminals on its circuit board and each terminal required nine volts ( two series of three V connected together ) then you would need four CR2025s preferably than fair two 2032s since there are doubly ampere many individual Volta cells in the 2025 battery .
If you are hush uncertain of which one to choose, it is best, either way, to use CR2032s alternatively of 2025 batteries since they have a higher energy concentration per bulk and last longer with even usage .

Current capacity

The CR2032 is besides preferable if your electronic device requires a higher stream capacity. If you are designing an application that needs say, 10 amps alternatively of 3-5 – it is good to use 2032s preferably than 2025 batteries since they can provide more ability in fewer cells at once .
In the same way, if you need a higher current capacity from your device than what 2025 batteries can provide, then it is besides judicious to use 2032s alternatively. If you are uncertain of how many cells will be needed for your application and whether or not to choose CR2025 vs. CR2032 – it may be best barely to go with 2032s all around since they last longer and do not require indeed a lot space in comparison .
The electric potential difference between 2025 and 2032 does not in truth play a part when deciding which one to get ; both have about 6 volts while operating normally ( without being drained ). The main factor that should influence this option is energy concentration : how hanker each barrage lasts depends on its size ( mAh ), the measure of power that can be stored in each cell. therefore, it is good to use CR2032s alternatively of 2025 batteries for applications requiring higher current capacity and any device needing higher voltage than what the 2025 barrage provides.


What is a coin cell?

A coin cell, or release barrage as it ’ second sometimes called, refers to the little, cycle batteries typically found in wristwatches and hearing aids. They can besides be used for keyless introduction systems on cars and other types of electronics .

What are common uses for CR2025 and CR2032 batteries?

CR2025 and CR2032 batteries are used for many devices including car key flim-flam, aesculapian equipment, watches, digital scales, game controllers, and more. These batteries can be found everywhere ! so whether you ’ ra looking for replacements or just want some out-of-stock items on this list at base ; these two batteries will never let you down .

Can you use a 2032 battery in place of 2025?

Yes, the 2032 battery is a bigger brother of the 2025 and it works in most devices that use a CR2025 battery. The only difference between these two batteries is their size : while 2025 has a diameter of 0.45 inches and stature of 0.04 inches, 2032 measures 0.47 x 0.03 inches .
Is it all right to use the CR2032 in your watch if you ’ ve been using a CR2025 ? It is not recommended because you are putting your battery at risk. however, it should be all right ampere hanker as you make sure that none of its parts have come into contact with metallic objects or other batteries before being used. If this has happened, don ’ deoxythymidine monophosphate put the new one in until everything has dried wholly and placed it somewhere without humidity for up to 24 hours just to be safe .

What battery can replace CR2025?

CR2032 is a popular battery alternate to CR2025. They are much used in calculators, watches, sensors, and early electronic devices. If you have lost the original CR2025 battery from your device or want to replace it with something of better quality, then you can use this alternative rather. A CR2032 battery has much the same dimensions as the CR2025 and is much used for similar purposes .
The most significant dispute between these two batteries is their voltage. A CR2025 holds a voltage of about up to 220 mAh whereas a CR2032 can reach up to 300mAh. This means that if your device needs a high power capacity then you should choose a CR2032 over a CR2025 model .

How long does a CR2025 battery last?

CR2025 batteries have a capacity of 220 mAh and end for about 3 years .
CR2032 batteries have a capacity of 315 mAh, but will besides die after 3 years deoxyadenosine monophosphate well .
Both types are frequently used in watches and other minor devices where the barrage is expected to end at least half a ten before being replaced .

Is CR1616 the same as CR2025?

It is a common misconception that CR1616 and CR2025 are the lapp battery type. In reality, they have similar forcible dimensions but different electrical properties angstrom well as different capacities. While both batteries measure 20 millimeter in diameter by 16 mm thick, their weight differs significantly with the CR2025 weighing about doubly vitamin a much as its smaller “ cousin ” at about 32 grams each versus 15 grams for a CR1616 .

What is the best CR2025 battery?

There are many brands. For example, RAYOVAC ’ randomness CR2025 is a great choice. This barrage can be used in many devices including :

  • Wireless keyboards and mice;
  • Keyless entry systems, garage door openers, and car alarm remotes;
  • Home electronics such as wall clocks and cordless phones;
  • Calculators;
  • Thermostats;
  • PDA;

How do you test a 2025 battery?

A 2025 battery is one of the most park coin cell batteries for watches and calculators. It ’ mho besides easy to test using a multimeter. You can check the voltage of 2025 batteries with your meter, but you ’ ll need to know if it is not working correctly before testing this way because there are many like voltages that indicate the battery has failed or will fail soon .
If you turn on your watch and find that it doesn ’ metric ton ferment by rights – for example, displaying an mistake message alternatively of showing discipline clock time – then chances are good that either one or both cells in its 2-cell 2025 battery have died. If only one cell appears all in, try replacing them one at a time by pulling out the old cellular telephone inaugural and inserting a new one adjacent after checking voltage again before putting it back together .
One final thing about testing 2025 button cells : be sure to put your meter in the adjust manner or you will not get an accurate recitation ! If you ’ re using a digital multimeter, it ’ sulfur normally in volts mode by default option and can be switched to other modes such as current ( amps ), immunity ( ohms ), and diode test .
