### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Replacement battery received which works well
  

*by L***L on Reviewed in the United States on April 7, 2020*

Updated review on 26May2020: After sending a message to the vendor, they send me a replacement one from a different batch.  The new one was charged up yesterday and it works well - finishing my routine cleaning and there was still some power left!  Cross my fingers the new one will last. 5 stars for the good customer service!Update: After 6 month of routine use of my Dyson vac, the battery still holds very strong.  I am very happy with this replacement.  Two thumbs up, highly recommend!  I would buy this brand soon again for my 2nd Dyson vac -  the battery is failing after 3 years.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent customer service
  

*by A***I on Reviewed in the United States on August 22, 2020*

Update:The seller reached out to me and promptly replaced the two original packs. The new ones are obviously from a different batch (even the batch font used to engrave the batteries looks higher quality) so hopefully these will last. For now, they work as expected.Original Review:I purchased two of these to replace my original Dyson packs, which had lasted me around 6 years but were getting down to about 10-15 minutes of run time. These batteries initially worked well, but within the last month, they both took a massive turn for the worse. At this point, they are unusable, literally giving out after anywhere from 30 seconds to 2 minutes, regardless of how long I leave them to charge.

### ⭐ 1.0 out of 5 stars







  
  
    Short Battery Life
  

*by G***B on Reviewed in the United States on July 16, 2020*

(See update 1 and 2 below) I have bought two of these now (we have two handhelds) and they have so far worked perfectly. As for longevity, only time will tell for sure. But, so far, I am very happy and would recommend these replacements.Update:  The battery was dead when I went to use the DC31. Amazon is sending me a replacement. I hope this isn't indicative of what I can expect from these batteries.  The original Dyson batteries lasted at least 6 years.UPDATE 2:  These batteries are fairly cheap and fit and work..... for a while. I have been lucky to get a year out of one (have had 4 now) before they crap out after only using for about 30 minutes during the whole period. Will I buy one of these again? Certainly not. Original Dyson batteries may cost more but a 6 year Dyson OEM lifespan is well worth it.
