## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Worked straight out of the box
  

*by O***T on Reviewed in the United States on January 5, 2020*

My old battery would not charge above 30% and this battery is now charged at 100%.  I have had the old battery for at least 4 years so I am not too disappointed.  I hope to see the same life out of this one.  I would definitely purchase another because the price could not be beat.

### ⭐⭐⭐⭐⭐
