V7 Battery-6.0ah with 2Filters

Bought this in December 2024. Worked great out of the box. Used it a few times a month. Now, after 8 months, it won't hold a charge. Don't waste your money. By an OEM and not one on these cheap knock offs because you get what you pay for. Edit: My bad. Changing rating to five star. I discovered that my filter was clogged and was preventing my vacuum from working properly. I thoroughly cleaned the filter and it's working like new.

I ended up purchasing 2 of these batteries and neither of them lasted even 2 months. The first one stopped charging a few days after the return period ended (30-ish days) I ended up buying a 2nd in order to send the 1st back as I didn't hear back from the seller on the matter. The 2nd one lasted a whopping 2 weeks, and it failed in a odd way. The way the Dyson V7 turns on is the trigger pushes down a plastic rod and that presses in on another rod that's in the battery casing itself (You can see it on the top of the battery shaft when you remove it from your vacuum) So the actual "Switch" is in the battery itself. In case you ever try to test the battery outside of the vacuum and aren't getting a reading on a multimeter, it's because the contacts on the battery itself don't supply any power until the switch is pressed. Well my 2nd battery was put on the charger and it suddenly started running. I thought the trigger might have gotten stuck, but after a few whacks with a rubber mallet it seemed that wasn't the issue. So I grabbed my small screwdriver and quickly removed the 3 screws holding the battery in and yanked it out of the vacuum. I could immediately tell that something inside the battery had failed as it smelled horrible and was quite hot to the touch. I left it outside in my driveway on the concrete in case the batteries ended up catching fire. I messaged the seller yet again and explained all of this and they still haven't replied a year later. So don't waste your time or $ on this particular brand, find one that will actually respond to messages and sell a product that will last a lot longer than just the 30 day return period window.

I originally gave this product a bad review because after 5 months our Dyson started pulsating like it had been before we bought this battery. After ordering a battery from Dyson it did the same thing. After troubleshooting we found out that our Dyson was clogged. We changed the filter when we replace the battery 5 months ago. I will say this loud for those in the back (my husband) DO NOT USE THE DYSON AS A SHOP VAC! Last fall My husband used the Dyson in the garage to vacuum saw dust…even though I pointed out the Dyson is not a shop vac! Then our Dyson started pulsating so he thought it was the battery. He changed it with this battery and the filter that came with the battery. Well, once again he vacuumed up sawdust and we had vacuum problems so we ordered a battery from Dyson. It turned out that the new filter was clogged from sawdust! I will be returning the Dyson battery and taking the $100 we spent on the Dyson battery and putting it towards a shop vac for that man! 🙄 🤣🤣 This battery is doing a good job and stays charged longer than the original dyson battery…as long as you don’t vacuum up sawdust! 🤦‍♀️

[Update: nearly three years of regular use, and the switch gave out, stuck on. The battery is strong. I had to remove it to stop the motor. But that’s a good run. I’m here to buy another.] Buy it. Read on to see how I fixed the one issue we had. I had picked this out for my girlfriend, but she was skeptical and wouldn't buy it. She kept complaining about her nearly dead Dyson, so I bought for her. She couldn't be happier about her Dyson now. She says it still doesn't last long on Max, but it's ok because she can go for two weeks without charging instead of daily. That said, we did have an issue with the alignment on our wall mounted charger, but it was fixable. Sometimes it would work fine, others it wouldn't charge, or dock, sometimes it got stuck. It's possible this battery was made to different specs or tolerance. Or maybe the hairline fractures I noticed on our vaccuum allow a little movement. For the price I don't care. I used a little diy engineering (basically a tourniqet) to secure the battery in the right spot and we haven't had any issues. If the misalignment was caused by a crack in the vacuum, a Dyson replacememt would have had the same problem.

This battery was easy to install and holds a charge well, providing more power than original battery. The only reason I gave 4 stars instead of 5 is because of the fit. It doesn't fit into the charger like the original battery. It takes a little bit of force to connect it. Hopefully this won't cause a problem over time.

I should have believed the other customer reviews. Yesterday this battery went dead. I am passed the return date, and I would like to think that Amazon would remove this product from their store listing. This is my first experience where this is a fraud and clearly a bad, bad, bad product. I would give the product a negative -10 rating

This battery arrived quickly, with instructions on how to exchange it on the vacuum. It was an easy task, and the battery fit the vacuum well - the screw holes lined up just fine. The charging port fits, but it's pretty tough to unplug the vacuum- I feel as if I'm going to break something with I go to pull it out of the wall mounted charging station. So far it hasn't broken, though, I've used it about 8 times since I bought the new battery. The vacuum had been lasting about 30 seconds tops on a charge with the old battery, and now lasts long enough for me to do my whole kitchen and dining area, as well as my hallway and a bedroom.

Fairly easy to install. Works perfect. Great Price
