💡 Tips for Choosing and Using Batteries Wisely

• ✔️ Don’t remove the tab until you’re ready to insert the battery
  
  

• ✔️ Allow 1–2 minutes after removing the tab before insertion (activates zinc-air)
  
  

• ✔️ Store in a cool, dry place – avoid the fridge
  
  

• ✔️ Keep spares if you live in remote or rural areas
  
  

• ❌ Never mix battery sizes or brands in one device
