Precautions
- Do Not Recharge: The CR2032HR is a non-rechargeable primary lithium battery. Recharging may cause gas generation, leakage, overheating or explosion.
- Avoid Direct Soldering On Cell Body: High temperature will damage internal sealing structure. Please adopt pre-welded tab batteries or battery holders.
- Do Not Short-Circuit: Direct connection of positive and negative poles will trigger high current, resulting in extreme temperature rise.
- Correct Polarity Installation: Confirm positive and negative alignment during assembly to prevent equipment malfunction.
- Safe Disposal: Do not crush, disassemble or heat the cell above 125°C. Dispose according to local lithium battery regulations.

Frequently Asked Questions
Q1: What is the main difference between standard Maxell CR2032 and CR2032HR?
A: Standard CR2032 operates at -20℃ ~ +70℃. CR2032HR uses special heat-resistant materials and sealing structure, supporting -40℃ ~ +125℃, designed for high-temperature automotive and industrial environments.
Q2: Is the Maxell CR2032HR rechargeable?
A: No, CR2032HR is primary non-rechargeable Li/MnO₂ battery. For rechargeable coin cells in same form factor, you can select ML2032 series.
Q3: Why is CR2032HR widely used for Automotive TPMS and industrial sensors?
A: Automobiles and industrial machinery generate extreme heat, vibration and mechanical shock. CR2032HR can withstand high temperature and centrifugal force while maintaining stable long-term output.
Q4: Can custom solder tab pins or wire leads be supplied for CR2032HR?
A: Yes. We offer factory-processed CR2032HR with vertical/horizontal solder tabs, insulated lead wires and micro connectors according to requirements.
Q5: Can I directly replace ordinary CR2032 with CR2032HR?
A: Same dimension and voltage, mechanically interchangeable. If your equipment works under high temperature or strong vibration, upgrading to CR2032HR will improve reliability; no modification needed for hardware.
Q6: What are the risks of soldering directly on the battery casing?
A: Direct high-temperature soldering will damage internal sealing, cause leakage or early failure. Please choose pre-tabbed batteries or use plastic battery holders.
Q7: How long is the shelf life of CR2032HR?
A: With ultra-low self-discharge rate below 1% per year, the typical shelf life can reach 8–10 years when stored under normal room temperature.
Q8: What is the difference between Maxell CR2032HR and Panasonic BR2032?
A: Both adapt to high-temperature scenarios. Maxell CR2032HR nominal voltage 3.0V, capacity 200~210mAh; Panasonic BR2032 can withstand higher peak temperature but has lower capacity. CR2032HR is more cost-effective for most TPMS and industrial sensor projects.
