CR2032 Battery Equivalent List and Cross Reference

When it comes to small, coin-style batteries, the CR2032 battery is one of the most widely used worldwide. You’ll find it powering a huge range of everyday electronics — from key fobs, car remotes, and calculators to digital thermometers, toys, and even some medical devices. Because it’s so common, many brands manufacture their own version of the CR2032 under slightly different codes and names.

This can cause confusion if you’re shopping for a replacement and see codes like DL2032, ECR2032, or 5004LC. The good news is: these are all equivalent to the same CR2032 battery size, chemistry, and performance standards.

What Does CR2032 Mean?

The name CR2032 follows an international standard. Each part of the code provides specific information about the battery:

• C – Lithium Manganese Dioxide chemistry (Li-MnO2)
• R – Round shape (coin or button cell)
• 20 – Diameter of 20.0 mm
• 32 – Height of 3.2 mm

So a CR2032 is a 3V lithium coin cell battery, 20 mm wide and 3.2 mm thick.

Common Applications

CR2032 batteries are chosen for devices that need steady, low-drain power over long periods. They are known for a shelf life of 5–10 years and dependable 220–240 mAh capacity. Popular uses include:

• Car key fobs and garage remotes
• Motherboard CMOS memory
• Watches and small clocks
• LED tea lights and toys
• Blood glucose monitors and digital thermometers
• Fitness devices and heart rate monitors

CR2032 Battery Equivalent Names

Depending on the brand and region, you may see the CR2032 sold under alternative labels. These are not different batteries — they are direct equivalents.

Some of the most common include:

• DL2032 – Duracell
• ECR2032 – Energizer
• BR2032 – Panasonic (alternate chemistry, slightly lower capacity but longer shelf life in standby devices)
• 5004LC – IEC standard code
• SB-T15 – Seiko
• KCR2032 – Kodak

Tips for Buying a CR2032 Replacement

1. Stick to trusted brands – Cheaper no-name versions may not last as long or maintain voltage as steadily.
2. Check expiration dates – Always buy fresh stock; a battery that’s been on the shelf for years will have reduced capacity.
3. Buy in multi-packs – If you use CR2032s frequently (for key fobs, lights, etc.), multi-packs are more cost-effective.
4. Confirm the size – While CR2032 is standard, some devices use similar but different coin cells (CR2025, CR2016). Always check your device manual.

Conclusion

The CR2032 lithium coin cell is one of the most universal batteries in use today. Its multiple equivalent codes — like DL2032, ECR2032, or 5004LC — all refer to the same standard 3V coin cell. By using the cross-reference chart above, you can confidently choose the correct replacement regardless of which brand your device originally came with.

Whether it’s for a key fob, watch, or medical device, having a fresh CR2032 on hand ensures your electronics keep running reliably.
