CR2016 Battery vs CR2032: What’s the Real Difference?

You open a device, remove the coin battery, and see a familiar marking: CR2016 or CR2032.
Both look almost identical. Both are 3V lithium coin cells. Yet using the wrong one can shorten battery life—or prevent your device from working at all.

So how do you actually decide between cr2032 battery vs cr2016?

The answer comes down to thickness, capacity, and power demand.

CR2032 Battery vs CR2016 at a Glance

Although battery cr2032 vs cr2016 share the same diameter and voltage, the CR2032 is twice as thick and stores more than double the energy.

CR2016 Battery: Size, Power, and Common Uses

What Is a CR2016 Battery?

A cr2016 battery is a thin lithium coin cell designed for compact, low-power electronics.
It delivers stable voltage while fitting into very slim battery compartments.

Typical specifications:

• cr2016 3v battery

• Lithium manganese dioxide chemistry

• Capacity around 75–90 mAh

• Long shelf life (5–7 years)

This makes the lithium cr2016 battery ideal where space matters more than runtime.

Common Applications of CR2016 Coin Batteries

You’ll most often find a cr2016 coin battery in devices that draw very little current:

• watch battery cr2016

• cr2016 watch battery for slim analog or digital watches

• Calculators

• Fitness trackers

• Medical sensors

• cr2016 battery for key fob (select models)

If your device is ultra-thin, a cr2016 3 volt battery is usually the correct choice.

CR2032 Battery: Higher Capacity, Longer Life

What Makes CR2032 Different?

A cr2032 battery is thicker and significantly more powerful than CR2016.
That extra thickness allows it to store much more energy.

Typical specs:

• 3V lithium coin cell

• 225–240 mAh capacity

• Shelf life up to 10 years

• Better performance under continuous load

This makes cr2032 battery bulk packs popular for both consumers and businesses.

Common CR2032 Battery Uses

Devices that need longer runtime or higher discharge rates usually require CR2032:

• cr2032 key fob battery

• cr2032 battery for Toyota key fob

• key fob battery cr2032

• Computer motherboards (CMOS)

• Medical devices

• watch battery cr2032

• Electronic toys

Can CR2016 and CR2032 Be Used Interchangeably?

Physical Fit: Usually No

Although both batteries are 20 mm wide, thickness matters.

• CR2016 = 1.6 mm

• CR2032 = 3.2 mm

A CR2032 often will not fit into a CR2016 slot.
A CR2016 in a CR2032 slot may sit loose and lose contact.

Electrical Performance Differences

Even though both provide 3V, their capacity is very different:

• CR2016 drains faster in high-power devices

• CR2032 delivers longer, more stable runtime

Using the wrong battery can cause:

• Short battery life

• Device malfunction

• Connection issues

Always follow the device manual.

CR2016 Battery Equivalent: What You Should Know

There is no true cr2016 battery equivalent with the same thickness and capacity.

Some devices allow:

• Two CR2016 stacked instead of one CR2032
  ⚠️ This is not recommended unless explicitly stated by the manufacturer.

Voltage stacking can damage electronics.

How to Choose Between CR2016 and CR2032

Choose CR2016 If:

• Your device is ultra-thin

• Power demand is very low

• Battery compartment specifies CR2016

• You need a watch battery cr2016

Choose CR2032 If:

• Device requires longer battery life

• Power draw is moderate to high

• Used in key fobs, toys, or medical devices

• You want cr2032 battery bulk for long-term use
