## FAQs Section
Common queries addressed regarding CR1220 battery equivalents.
**Can I use a CR1225 battery as an alternative to the CR1220?**
While both are 3V coin cell batteries, the CR1225 is thicker (2.5mm vs. 2.0mm). it may fit in some devices with flexible terminals, but using a thicker battery can potentially damage the battery compartment or prevent proper contact in tighter spaces. Testing for fit and secure closure is advised before forcing it. Consider the device’s design before opting for this substitution.
**What are the safety precautions when handling CR1220 batteries and their equivalents?**
Always keep coin-cell batteries out of reach of children due to the danger of swallowing. Ensure correct battery polarity (+/-) when inserting, and avoid storing batteries in direct sunlight or high-temperature environments. Recycle spent batteries at designated collection points to minimize environmental impact and potential hazards.
**How do I properly dispose of CR1220 battery equivalents?**
Dispose of used coin-cell batteries through local recycling programs or battery collection sites. Many electronic stores and waste management facilities provide designated bins for battery recycling. Check the local regulations for specific instructions to ensure responsible disposal and minimize environmental harm.
