What is the difference between LIR 2032 and CR2032 battery?

Last updated: June 4 2026 | For consumers, engineers, OEM buyers and product developers choosing between LIR2032 rechargeable coin cells and CR2032 lithium coin cells.

LIR2032 vs CR2032 battery comparison

Quick Answer

LIR2032 and CR2032 have the same physical size, but they are not the same battery. Both are about 20mm in diameter and 3.2mm thick. However, LIR2032 is a rechargeable lithium-ion coin cell with a nominal voltage around 3.6V or 3.7V, while CR2032 is a non-rechargeable lithium manganese dioxide coin cell with a nominal voltage of 3V.

Do not replace CR2032 with LIR2032 unless the device clearly supports 3.6V–3.7V rechargeable coin cells. Do not charge CR2032 batteries. Using the wrong battery may cause poor performance, leakage, overheating, device damage or safety risks.

Safety Warning

CR2032 batteries are not rechargeable. Never charge, open, puncture, heat or short-circuit a CR2032 battery. LIR2032 batteries should only be charged with a compatible charger or charging circuit designed for rechargeable lithium-ion coin cells.

What Is a CR2032 Battery?

A CR2032 is a 3V non-rechargeable lithium manganese dioxide coin cell battery. It is widely used because it is compact, affordable, stable in low-drain applications and has a long shelf life when stored correctly.

CR2032 Is Commonly Used In

  • Car key fobs
  • Watches and calculators
  • Medical devices and digital thermometers
  • Remote controls and small sensors
  • Computer motherboard CMOS backup
  • Security devices and meters

What Is a LIR2032 Battery?

A LIR2032 is a rechargeable lithium-ion coin cell battery with the same 20mm × 3.2mm physical size as CR2032. Its key advantage is rechargeability, but its voltage is higher than a standard CR2032. That difference makes compatibility more complex.

LIR2032 Is Better Suited For

  • Devices specifically designed for rechargeable coin cells
  • Small electronics with compatible charging circuits
  • Applications requiring repeated charge and discharge cycles
  • Projects where the circuit supports 3.6V–3.7V operation

Can LIR2032 Replace CR2032?

Usually, no. Although LIR2032 and CR2032 are the same size, LIR2032 has a higher voltage. A device designed only for a 3V CR2032 battery may not tolerate 3.6V–3.7V input.

Situation
Can You Use LIR2032?
Reason
Device manual says CR2032 only
Not recommended
The device may be designed for 3V only.
Device says CR2032 / LIR2032 supported
Yes
The manufacturer has confirmed compatibility.
Device has built-in charging circuit
Possible
Only if the charging circuit is designed for LIR2032.
Car key, watch, calculator or remote
Usually no
Most are designed for standard 3V CR2032 batteries.

Can CR2032 Replace LIR2032?

Sometimes CR2032 can physically fit where LIR2032 is used, but it is not always electrically suitable. CR2032 has a lower voltage and cannot be charged. If the device expects a rechargeable LIR2032 or has a built-in charging circuit, CR2032 should not be used.

Important: Never place a CR2032 battery into a device that will try to recharge it. CR2032 is not designed for charging and may leak, overheat, swell or rupture.

What Happens If You Charge a CR2032 Battery?

Charging a CR2032 battery is unsafe. CR2032 cells are primary lithium batteries, meaning their chemistry is designed for single-use discharge, not repeated charging.

Risk
What May Happen
Leakage
Internal pressure or chemical reaction may cause electrolyte leakage.
Overheating
Charging current may generate heat and damage the cell.
Swelling or rupture
Gas buildup may deform or rupture the battery.
Device damage
Leaking or overheating batteries may damage the battery compartment or circuit board.

Which Battery Should You Choose?

Choose CR2032 If

  • Your device manual specifies CR2032 or 3V coin cell power.
  • You need long shelf life and stable low-drain performance.
  • The device is a key fob, remote, watch, calculator, meter or medical device.
  • You want a simple replacement battery without charging.

Choose LIR2032 If

  • The device specifically supports rechargeable LIR2032 batteries.
  • The charging circuit is designed for lithium-ion coin cells.
  • The device can safely operate at 3.6V–3.7V.
  • You need repeated charging instead of single-use replacement.

Application Guide

CR2032 and LIR2032 battery applications

Application
Usually Better Choice
Why
Car key fobs
CR2032
Most key fobs are designed for 3V primary coin cells.
Watches and calculators
CR2032 or specified CR-series battery
Low-drain devices usually need long shelf life rather than rechargeability.
Medical devices
Follow device manual
Safety, reliability and validated compatibility are most important.
Small rechargeable gadgets
LIR2032 if supported
Rechargeable coin cells are useful only when the charging design is compatible.
USB rechargeable devices
LIR2032 if circuit supports it
The charging circuit must match LIR2032 voltage and charging requirements.
IoT and smart devices
Depends on voltage and charging design
Engineers should evaluate voltage tolerance, standby current and maintenance requirements.

OEM and B2B Battery Selection Considerations

For OEM projects, LIR2032 vs CR2032 selection should not be based only on physical size. Engineers and buyers should evaluate voltage tolerance, charging circuit, expected runtime, safety, certification, storage life, connector or tab requirements and long-term supply stability.

Design Factor
What to Confirm
Voltage tolerance
Whether the circuit accepts 3V only or 3.6V–3.7V operation.
Charging circuit
Whether the device charges the coin cell and whether that circuit is designed for LIR2032.
Runtime target
Whether the device needs long shelf life or repeated recharge cycles.
Mounting style
Loose cell, battery holder, tabbed cell, leads, connector or PCB mounting requirement.
Documentation
MSDS, UN38.3, RoHS, REACH or market-specific documents where required.

FAQ

Is LIR2032 the same as CR2032?
No. LIR2032 and CR2032 are the same physical size, but they have different chemistry, voltage and rechargeability. LIR2032 is rechargeable and usually 3.6V–3.7V, while CR2032 is non-rechargeable and 3V.
Can I use LIR2032 instead of CR2032?
Only if the device clearly supports LIR2032 or 3.6V–3.7V rechargeable coin cells. Do not use LIR2032 in a device designed only for 3V CR2032 batteries.
Can I charge a CR2032 battery?
No. CR2032 is not rechargeable. Charging it may cause leakage, overheating, swelling, rupture or device damage.
Why does LIR2032 have higher voltage than CR2032?
LIR2032 uses rechargeable lithium-ion chemistry, which normally has a nominal voltage around 3.6V–3.7V. CR2032 uses primary lithium manganese dioxide chemistry with a nominal voltage of 3V.
Which lasts longer, LIR2032 or CR2032?
It depends on the application. CR2032 often has long shelf life and good low-drain performance, while LIR2032 can be recharged many times if the device supports it. For standby devices, CR2032 is often preferred. For repeated recharge use, LIR2032 may be better.
Can CR2032 replace LIR2032?
Sometimes it may fit physically, but it is not always suitable. CR2032 has lower voltage and cannot be charged. If the device expects a rechargeable LIR2032 or has a charging circuit, CR2032 should not be used.
What battery can replace CR2032?
The safest replacement is another CR2032 from a reliable manufacturer. CR2025 or CR2016 may share the same diameter but are thinner and lower capacity. LIR2032 is rechargeable but has higher voltage and should only be used if the device supports it.
Does PKCELL supply LIR2032 and CR2032 batteries?
PKCELL can support coin cell battery sourcing and selection for OEM projects, including CR-series lithium coin cells and rechargeable coin cell applications where suitable. Buyers should confirm exact model, voltage, charging requirement and documentation needs before ordering.

Conclusion

LIR2032 and CR2032 look similar because they share the same 20mm × 3.2mm size, but they are not interchangeable by default. LIR2032 is rechargeable and usually has a higher voltage, while CR2032 is a non-rechargeable 3V lithium coin cell.

For replacement use, follow the device manual. For OEM projects, choose based on voltage tolerance, charging design, runtime, safety, mounting method, certification and long-term supply requirements.
