    Accoessory
  

*by B***W on Reviewed in the United States on October 15, 2020*

Battery works just fine as a replacement. It charged and is good to go. The cord that came with it would have been better if it had been a wall charge cord. Much more practical.

    Better battery than the original!
  

*by D***R on Reviewed in the United States on November 26, 2019*

Bought two batteries: this one and an OEM. OEM takes longer to charge and did not hold a charge as long as this one did.
