## Customer Reviews

### ⭐ mAh rating incorrect!
            
*by J***X on October 27, 2019*

Tested all 4 batteriesNot 3,400 mAh each, only 1,200 mAh each
  

### ⭐ Don't bother.
            
*by P***A on October 26, 2019*

The batteries upon install instantly fried my smart doorbell. The batteries I had in these before had no such issues. So now I'm out of the money I spent for these batteries and a smart doorbell. Thanks Guys!
