Physical Specifications and Technical Factors

A brief overview of CR2032 and CR2016 batteries

As discussed earlier, CR2032 and CR2016 coin cell batteries vary in dimensions and capacity while sharing a distinctive 20mm diameter. The CR2032 is more sizable and offers more capacity (220 to 240mAh) contrasted with the thinner, more condensed CR2016 (90mAh).

Importance of understanding the differences

Identifying the capacity and size differences between these generally used lithium batteries permits proper battery selection for any specified application.

Common use cases for both battery types

The CR2016’s miniature form factor outfits low-power thinning equipment like fitness bands or smartwatches. The CR2032 realizes use in most electronics requiring more runtime from a cheap 20mm lithium timepiece battery.

Physical Specifications

Dimensions and size of CR2032

The CR2032 coin cell battery calculates 20mm in diameter, with a general thickness of 3.2 millimeters. This gives it a little tall, slanted cylinder shape.

Size and dimensions of CR2016

At half the width of a CR2032, the CR2016 coin cell is presented in a 20mm x 1.6mm diameter with x height. This thin shape aids in suiting cramped electronics.

Visual comparison between CR2032 and CR2016

When positioned side by side, the CR2016’s thinner form is very deceptive compared to the CR2032 despite sharing an equivalent 20mm width. The CR2032’s supplementary capacity comes from its additional internal volume and 3.2mm diameter.

Capacity and Voltage

Capacity of CR2032 battery

As presented earlier, the CR2032 lithium coin cell battery has a distinctive capacity of 220 to 240mAh. This milliamp-hour (mAh) rating says it can provide 220-240mA of current gradually for 1 hour before being entirely depleted.

Capacity of CR2016 battery

The CR2016 has a minor nominal capacity of about 90 to 95mAh. Thus, if used to source a constant 90mA load, it would deplete in almost 1 hour.

Voltage specifications for both batteries

Notwithstanding a 2X capacity difference, both CR2016 and CR2032 offer the same operational voltage of 3V. They use similar lithium chemistry to deliver a standard button cell-rated output. Their same 20-millimeter width also represents both batteries are substitutable in holders imagining 3V supplied across clips 20mm separately.

Key Differences

Exploring the variations in battery capacity

The CR2032 delivers a typical capacity of 220-240mAh associated to 90-95mAh in the CR2016. This 2 to 3X difference unequivocally impacts the operational runtime when consumed in devices.

Voltage discrepancies between CR2032 and CR2016

There are no voltage differences per se – both batteries keep a nominal 3V output. The difference lies in the longevity of holding 3V and capacity. The CR2032 can offer 3V for 2 to 3X longer before dropping voltage.

Implications of using one type over the other

The lesser capacity CR2016 would require to be interchanged 2-3X more often in equipment intended for a CR2032. Using a CR2016 could cause unexpected battery exhaustion and glitches or device shutdowns. Devices imagining 220mAh would not have at least runtime reserves of just 90mAh.

On the other hand, the thicker CR2032 may not suit more compact devices intended strictly for the thin CR2016 body. Physical pressure could impair circuits not constructed to control the additional thickness.


Can I use CR2032 instead of CR2016? 

The CR2032 is too compact to fit into devices precisely for the narrow CR2016 battery correctly. Trying installation could permanently mutilate the device not created for the larger coin cell thickness.

Can I use CR2016 instead of CR2032?

While the CR2016 can usually fit into CR2032’s planned devices, its lesser capacity will only offer enough runtime for a part of the CR2032’s intended lifecycle. Unexpected shutdowns or Premature voltage drops can happen.

Comparative Analysis

Side-by-side evaluation of CR2032 vs. CR2016

To review critical factors parallelly: The CR2032 battery has higher capacity and is thicker than the CR2016, which is thinner with less power. Their voltage output is identical to 3V nominal.

Highlighting specific scenarios

Where may one be chosen? The 1.6-millimeter thick CR2016 would be selected if an ultra-slim shape is required. When extended runtime is needed, and a 3.2mm thickness is permissible, the CR2032 is possibly the best fit.

Real-world examples showcasing the practical differences

A smartwatch created to be very slim may only have physical consent for a CR2016 battery. Similarly, a television remote control with extra internal space would be capable of leveraging the CR2032 for several months of additional operation per change.

Exploring common misconceptions

Common fallacies are that the CR2016 and CR2032 can be easily swapped or last for the equivalent duration. In reality, their exclusive capacities and shapes make substitutable use entirely restricted.

Clearing up confusion regarding their similarities

While their 3V voltage and 20-millimeter diameter may seem comparable at first glance, the CR2032 battery delivers over 2X the capacity in a profuse profile compared to the CR2016. These internal differences matter.

Addressing the belief that they are entirely interchangeable

Aside from suiting some usual 20mm battery holders, the CR2032 and CR2016 should not be used exchangeable in most applications due to distinctions in device dimensions and intended lifespan. Always coordinate new batteries with the innovative OEM specifications.


Providing recommendations based on specific use cases

If swapping batteries in an old application, match the standby to what was initially quantified by the manufacturer’s model dimensions and number for optimal runtime and safety.

Final thoughts on choosing between CR2032 and CR2016 batteries

In conclusion, while sharing a 20-millimeter width, differences in capacity and thickness make the CR2032 and CR2016 suitable for specific non-interchangeable uses based on device size requirements and power.
