Bonadget6.0Ah 21.6V V7 Battery Replacement Compatible with Dyson V7 Animal Battery SV11 Battery for Dyson V7 Motorhead V7 Absolute Battery with Pre-Filter

[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.

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.

This battery works good if used shortly after charge. My battery will not hold a a charge four to seven days . I can not recommend the battery . Glenn Van Winkle

Works like new!

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.

Fits and holds a charge longer.

Im not sure if it was bad luck or this product is absolutely trash, the battery was treated following all specifications including charging periods, I was only able to use it 5 times and now the battery doest revicve charge; the charger and everything is been checked, and everything points at the battery just been a bad product.I'm not sure if it was bad luck or if this product is simply defective. I followed all the specifications for treating the battery, including the charging periods, but I was only able to use it five times before the battery stopped receiving a charge. I've checked the charger and all other components, and everything suggests that the battery is simply a poor-quality product.

Fit perfectly, easy to install.the price was right .
