## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Better than the original
  

*by M***N on Reviewed in the United States on June 22, 2023*

Gave new life to my Dyson, runs far longer than the original battery ever did. Not surprising as it has double the amperage rating.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect replacement
  

*by P***B on Reviewed in the United States on December 21, 2020*

Delivered in less than a day!  Fits my Dyson DC45 perfectly and I am looking forward to extended run time with this 4.0ah battery as opposed to the original 2.5ah battery.  Longevity is still to be seen, but I think the price was very reasonable.

### ⭐ 1.0 out of 5 stars







  
  
    Poor Battery Life
  

*by D***R on Reviewed in the United States on March 17, 2022*

We purchased this battery October 27, 2021.  Received and installed it sometime in early November.  Used it for November and December.  In January it started to fail.  It was not used at all in the month of February.  Today the  battery lasted less than five minutes after charging all night.  It's already out of warranty.  This was a total ripoff.
