Choosing the right CR2032 battery involves considering coating, packaging, and shelf life to ensure your AirTag stays powered and connected without issues.
Coating Type

Choose non-coated batteries to avoid connectivity issues and ensure reliable performance for your tracker.
Brand Reliability
Established brands like Duracell and Apple OEM sources often deliver consistent voltage and life. Check reviews for reliability over time to ensure your device stays powered when needed.
Prioritize trusted manufacturers with proven track records for quality and safety.

Child-proof or child-resistant packaging is crucial for households with young children. It prevents accidental ingestion and keeps batteries secure until use.
Always choose products with safety packaging to protect your family and pets.
