Review on KUNLUN 21.6V 4.0Ah V6 Battery Replacement For Dyson DC59 DC62 DC58 SV04 SV03 SV07 SV09 VCT4 V6 Animal Motorhead Absolute Slim 967810-23 Cordless Vacuum Battery by Tammy Stephens

I got the battery in January 2021 and it worked fine for a few months. I went to use it the other day and it was completely dead, and will not charge at all.Update - the company did offer to replace the battery or give me a refund after the return period had expired. So I give them credit for that.
