What Are the Differences Between CR2032 and CR2025 Batteries?

By now, you are familiar with the short differences. But there is a lot more to know about them. So, let’s find out a detailed explanation of the differences between CR2032 and CR2025 Batteries.

Cr2032 Vs Cr2025 Coin Cell Battery Comparison

Thickness

Battery thickness has a large impact on battery capacity, energy density, and overall heat generation. In terms of thickness, CR2032 is 0.7mm thicker than CR2025.

Thus, cr2032 offers more capacity than its competing battery. And when speaking about thickness, the CR2025 battery is 2.5mm, whereas the CR2032 battery is 3.2mm.

Power density

When comparing power density, the CR2032 battery has a higher power density than the CR2025 battery. Therefore, the CR2032 battery will charge more quickly than the CR2025 battery.

Power density refers to the ability of the battery to absorb and deliver electricity. Usually, this quantity is given as Watt-hours per kilogram (Wh/kg).

A battery with a higher power density will charge more quickly than one with a lower power density. The battery’s power capacity directly affects how long it can be used.

Capacity

Standard CR2032 batteries have a nominal capacity of 235mAh, while typical CR2025 batteries have just 170mAh.

The thinner battery could not endure as long and might need to be changed more frequently because of its lower capacity. Because of its capacity, the CR2032 has more power that keeps going for a while than the CR2025.

Durability

Long durability of any product is usually desired by the customers. The CR2032 battery is more durable and long-lasting than the CR2025 battery.

A CR2032 battery in a car key fob might last up to 4-5 years before it needs to be replaced. On the other hand, a CR2025 battery used in a car key fob might not need to be replaced for 3 to 4 years. before it needs to be replaced.

Weight

A CR2032 battery weighs more than a CR2025 battery. It has a 3.0-gram weight. On the other hand, the CR2025 battery has a 2.6-gram weight. That means the CR2032 battery is going to provide more energy than its competitor.

Application

The CR2032 battery is used in a variety of apparatus and uses, such as calorie counters, calculators, computer motherboards, car key fobs, watches, PDAs, sports equipment, pedometers, stopwatches, and so on.

On the other hand, the amazing thing about the CR2025 battery is that it works better in products that need low current output and is easier to use in those products. Some of these things are pet collars, toys, pocket calculators, and so on.

Cost

In terms of cost, the CR2032 battery is more expensive than the CR2025 battery. Below, we have constructed a nifty table where a price range of CR2032 and CR2025 is shown to have even clearer ideas on the prices.

BatteryQuantityPrice
Duracell CR2025 3V Lithium Battery2 Count (Pack of 1)$5.90
Duracell CR2032 3V Lithium Battery6 Count (Pack of 1)$7.99 – $14.99

Can You Interchange CR2032 With CR2025 Battery?

In reality, yes, the CR2032 and CR2025 can be used through interchange, assuming they can be accommodated in the battery compartment. CRC2032 and CRC2025 should not be used interchangeably, as they may harm your battery.

However, the CR2032 will probably last a little longer because it has a bigger capacity (mAh).

To close the 0.7mm gap, (diameter gap 3.2-2.5 of two batteries) you can fold a sheet of aluminum foil or another conductor. Shut down the compartment and put it on top of the battery’s positive side to keep it in the location.

The battery may stop working if the battery and recoil are not connected in the right way. Even though this isn’t a wise decision because the CR2025 won’t endure as long in an apparatus made for the CR2032, it may be advantageous in an adverse situation.
