🔍 The Physical Difference – It’s All About Thickness

While both CR2032 and CR2025 are 20 mm wide, the CR2032 is 0.7 mm thicker.

• CR2032 = 3.2 mm
  
  

• CR2025 = 2.5 mm
  
  

This extra thickness gives the CR2032 more energy storage capacity (higher mAh), meaning it generally lasts longer in the same device.

🔄 Can You Interchange CR2032 and CR2025?

✅ Yes, but with caution.

• A CR2032 can sometimes replace a CR2025 if there’s enough space in the battery compartment and the device contacts still connect properly.
  
  

• A CR2025 can temporarily work in place of a CR2032 — but the battery will drain faster due to lower capacity.
  
  

📌 Always consult your device manual or remove the old battery to check the exact code.

❓ FAQ – CR2032 vs CR2025

Q1. Can I use a CR2032 in place of CR2025 in my car remote?
If the battery fits and the lid closes properly, yes. The CR2032 will last longer due to its higher capacity.

Q2. Is the voltage the same?
Yes, both are 3V lithium coin cells.

Q3. Why did my CR2025 drain so quickly?
Your device might require a higher capacity, or the cell was near expiry. Consider upgrading to CR2032 if space allows.

Q4. Are these batteries rechargeable?
Standard CR2032 and CR2025 are not rechargeable. Rechargeable variants exist (LIR2032), but they require special chargers and are rare in India.

Q5. Can I buy a mixed pack?
It’s best to buy dedicated packs by type to avoid confusion and device damage.
