    They fit and worked
  

*by C***I on Reviewed in the United States on June 22, 2019*

These worked well but I think you can get them without wait local at the a dedicated battery place for same price.

### ⭐ 







  
  
    Not happy, did not last past a month.
  

*by M***I on Reviewed in the United States on January 28, 2023*

The original battery in the unit lasted about a year, the replacement battery maybe a month. Not a good product in my opinion.
