Murata CR1632 Coin Cells: What to Know Before Buying a 10-Pack
Murata CR1632 batteries are 3V lithium coin cells often used as replacements for Sony CR1632 in devices like car key fobs, medical devices, and small electronics. This 10-pack offers convenience and value, but understanding compatibility, shelf life, and quality is key before purchasing.
Key Considerations Before Buying
- Voltage and size compatibility: CR1632 cells are 16mm in diameter and 3.2mm thick, delivering 3 volts. Always confirm your device requires this exact size, as CR2032 or CR1620 cells are not interchangeable and could damage equipment.
- Brand and authenticity: Murata is a reputable Japanese manufacturer, but counterfeit batteries exist. Purchase from authorized sellers and look for clear branding and lot numbers to ensure you receive genuine cells.
- Shelf life and storage: Lithium coin cells typically have a 5-10 year shelf life. Check the expiration date on the packaging and store them in a cool, dry place to maximize performance when needed.
What Our Analysts Recommend
Look for batteries with a clear expiration date, original packaging, and voltage consistency. Genuine Murata cells often feature a laser-etched model number and are sold in blister packs to prevent tampering. Avoid loose batteries or those with suspiciously low prices, as they may be counterfeit or degraded.

Review Authenticity Insights
Grade A Interpretation
With an authenticity grade of A and only 5% estimated fake reviews, this product's reviews are highly trustworthy. The high percentage of verified purchases further supports that the feedback reflects genuine customer experiences, making the 3.67-star rating a reliable indicator of mixed satisfaction.
Trust Recommendation
You can trust the overall sentiment in these reviews, but pay attention to specific complaints about battery life or compatibility. Since the rating is moderate, it's wise to read recent reviews to see if issues are consistent or isolated.
Tips for Reading Reviews
Focus on reviews that mention performance in specific devices, as coin cell experiences can vary by use case. Look for patterns in complaints about longevity or leakage, and note whether reviewers are verified purchasers to gauge credibility.
Expert Perspective
The Murata CR1632 10-pack offers a convenient solution for those needing multiple coin cells, especially for devices like car key fobs or medical equipment. While the product has a moderate 3.67-star rating, the high authenticity of reviews suggests that the feedback is reliable, highlighting both satisfaction and potential issues. Murata's reputation for quality adds confidence, but buyers should be aware that some users report shorter-than-expected battery life.
Purchase Considerations
Consider your device's requirements and how many batteries you need. If you only need one or two, a smaller pack might be more cost-effective. Also, check the expiration date to ensure you're getting fresh stock, as old batteries can lose capacity.
Comparing Alternatives
Compare with other brands like Panasonic or Energizer, and consider single packs if you don't need ten. Reading reviews for specific devices can help you choose the most reliable option.
