Overview of CR2032 and CR2025 Batteries

Continuing from our discussion on battery types, let’s investigate deeper into the specifics of two commonly confused models – the CR2032 and CR2025. These button cell batteries may seem identical at first glance, but subtle differences exist in their characteristics.

Characteristics of CR2032

Diving into details about the mighty little power source known as a “CR2032,” you’ll find that it boasts impressive specs. This coin-shaped lithium battery stands 3.2 mm tall with a diameter measuring 20mm across — hence its name ‘CR’ for cylindrical shape, ’20’ indicating its diameter and ’32’, denoting height.

One standout feature is capacity; this unit holds an average energy level around 220 mAh (milliampere-hours). That means more longevity for your devices! Being non-rechargeable though poses some limitations if prolonged use is anticipated.

Remember those digital scales or car key fobs running out? More often than not, they’re powered by these tiny troopers!

Characteristics of CR2025

Shifting focus to another crowd-favorite –the sleeker sibling: The “CR2025.” Slightly slimmer than its counterpart at just 25.mm high while maintaining that standard 20mm girth gives it apt nomenclature too.

But when comparing capabilities against size sacrifices become evident: A reduced stature translates directly to lesser stored juice–typically hovering near only160 mAh worth—roughly three-quarters what’s packed inside bigger brother “32”.

Even though lower reserves don’t discount usefulness entirely! Its compact nature makes perfect certain applications requiring thinner profiles like calculators watches without compromising overall functionality considerably due decreased thickness.

Physical Differences

Size and Shape

Comparing CR2032 to CR2025, the physical differences are evident. For instance, a standard CR2032 battery measures 3.2mm in height with a diameter of 20mm (size: 20×3.2), whereas its counterpart, the CR2025 model stands at just 25.mm high (size: 20×25). These dimensions play an integral part when selecting batteries for specific devices as it influences their fit.

Noticeably smaller and slimmer than the average coin cell battery types like the cr2016 or cr2430, both models have made their mark particularly in compact electronic devices due to their distinct size attributes; ideal for applications that demand minimal space consumption yet reliable power output.

Weight

Moving onto weight variations between these two commonly confused cells- there’s a clear distinction too! A typical sample of each will reveal that while they share identical diameters which is roughly about two-thirds less than your regular AA type – weighing around three grams apiece – , you’ll find out that even though being shorter by almost ten percent compared to Cr2032’s stature ,the latter still has more mass because it contains more active materials.

The difference might seem minute but every gram counts especially if we’re dealing with lightweight items such as wearable tech gadgets where comfortability equates functionality – remember nobody wants anything heavy strapped on them all day long!

Performance Comparison

Taking a closer look at the performance characteristics of both batteries, it’s evident that each has its strengths and weaknesses.

Voltage and Capacity

The CR2032 battery provides 3 volts with an impressive capacity rating of around 235 mAh. On the other hand, although offering similar voltage at approximately 3V, you’ll find that the CR2025 holds slightly less power with a typical capacity measuring about 163 mAh.

This indicates that if your device requires higher energy output for prolonged periods without frequent replacement intervals – think digital watches or medical devices – then opting for CR2032 may serve better given its superior charge storage.

Battery Type	Voltage (V)	Typical Capacity (mAh)
CR2032	~3	~235
CR2025	~3	~163

But, remember this doesn’t always translate to longer lifespan as it also depends on how much current your specific gadget draws from these coin cell batteries.

Longevity and Durability

In terms of longevity, thanks to their increased mass resulting from additional active materials mentioned earlier in our discussion on physical differences between them; unsurprisingly enough – thicker model i.e., CR2032 typically tends to last longer than thinner counterpart: namely; those under brand name “CR2025”. This becomes particularly important when considering applications where regular battery change-outs are impractical or inconvenient. But, bear in mind such endurance largely hinges upon usage pattern apart from mere size difference alone!

Typical Applications

Both CR2032 and CR2025 batteries find applications in a myriad of electronic devices. But, their use differs based on the power requirements of these gadgets.

Usage in Electronics

CR2032’s higher capacity makes it an ideal choice for electronics demanding more energy over extended periods. These include but are not limited to computer motherboards where they serve as CMOS batteries, preserving BIOS settings during power off situations. High-end calculators also leverage this battery type due to its ability to maintain operations under continuous usage.

On the other hand, you’d often spot a CR2025 in lightweight remote controls or small toys that don’t require high-power output for functioning optimally; owing primarily to its slimmer profile which allows seamless integration into compact designs without compromising device portability.

Usage in Medical Devices

Medical devices such as glucometers and digital thermometers prefer using CR2032 because longevity is crucial here – imagine having your thermometer fail right when you’re checking if someone has fever! Henceforth they opt for 235 mAh capacity offered by this variant even though it might add some bulkiness compared with its counterpart.

Contrarily, hearing aids usually employ cr2025 due mainly to their low-profile design making them suitable for integrating into delicate medical equipment like thin wrist-worn pulse oximeters or heart rate monitors wherein size constraint plays an imperative role alongside adequate performance yield within stipulated power confines provided by these slim-form-factor cells (163mAh).

Consumer Considerations

When choosing between CR2032 and CR2025 batteries, consider your specific needs. It’s not just about the physical characteristics or performance features; it’s also important to evaluate factors like price and availability.

Price Comparison

In general, both types of batteries are relatively affordable. The cost for each might differ slightly depending on the brand and where you buy them from.

For instance, as per a popular online marketplace in September 2021:

Battery Type	Average Cost
