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 Michelle Amin

Update- 1/14/22. After the 2nd battery died. Seller refunded my original purchase. They did send a 2nd batter to replace the one I purchased and when that one died they refunded me. At least this seller tries to make it right. :)Update 1/10/22.Replacement battery seller sent (12/21) died and will not charge after half a dozen uses. I give up and will buy a genuine Dyson battery or buy a new Dyson. These cheap after market replacement batteries are just not comparable to the real deal. Sorry.Update 11/30/21. Only 3 months old. Won't charge. Got 3 or 4 uses and it's dead. Junk. Buyer beware. Will order a Dyson battery.Easy to install, 1 screw to remove for taking out the old OEM battery and install new cheap knock off . have only used it a few times but so far I'm getting more physical run time compared to when my vacuum was new. Will update if anything changes.
