Safety and Maintenance Guidelines

• • Child Safety: Coin batteries pose a severe ingestion hazard; keep in original child-resistant packaging and store strictly out of reach of children and pets.
• • Handling Protocol: Handle batteries by the edges; avoid touching the flat surfaces with bare fingers as skin oils can increase electrical resistance and cause discharge.
• • Storage Environment: Keep in a cool, dry place; do not store batteries loose to prevent accidental short-circuiting against other metal objects like coins or keys.
• • Environmental Responsibility: Contains lithium; these batteries must be recycled at designated recycling points to ensure safe material recovery.

Common Frequently Asked Questions

• • What is the difference between a CR2032 and a CR2025 battery? Both are 3V lithium cells, but the 2032 is 3.2mm thick, whereas the 2025 is 2.5mm thick; always use the thickness specified by your device to ensure proper electrical contact.
• • Can these lithium coin batteries be recharged? No, these are primary lithium cells; attempting to recharge them can cause danger.
• • Why is my device not working with a new battery? Ensure the battery is correctly seated - usually with the positive (+) side facing up; clean the contacts with a dry cloth to remove any residue.
• • How long will these last in storage? When kept in a cool, dry environment, Energizer lithium coin cells typically retain their charge for up to a decade.
