Upgraded 6.0Ah V7 SV11 Battery 229687 Replacement for Dyson V7 Animal/Trigger/Motorhead Pro/Car+Boat/SV11 V7 battery replacement Handheld Cordless Vacuum Cleaner 21.6v Li-ion 6 cell 229687 Battery

Battery on my Dyson vac wouldn’t charge, OEM replacements were crazy expensive, this was an economical solution. Easy to install, it fit perfectly, looks just like the original, and it functions with the wall charge hanger that comes with the Dyson. It does know when to stop accepting a charge after the battery is full, so it’s not just sitting there pulling power all day long. 10/10 would recommend. Find it to hold as long of a charge as the original. No issues after several months of use.

I previously reviewed this when I got it at the end of Sept. 2023 and of course it worked fine then. Now, almost 4 months later it runs for about 2 minutes! This started a month ago. This is my third edit to this review. I bought a lithium ion battery capacity tester and dismantled and tested the batteries. See the image of the battery pack case that says it is 6000 mAh.There are 6 3.7v cells in series, that means each cell is adding up voltage to the 21.6 volts. However, that means the mAh don't change because it's wired in series. So each cell should be a 6,000 mAh capacity. I can't find anybody that makes one! You're lucky to get a decent 3,800 mAh 18650 lithium-ion single cell. I will note that each battery weighs 43g which is about right.Looking at my images, you can see that newly charged cells are around 4.14-5. 4.2 would be better, but this is okay. The next image shows the cutoff voltage the tester will use to calculate the cell's capacity. I first tried them at the default of 3.0v cutoff but changed to 2.6 (yes, I tried 2.7 also). The fourth image shows the tested capacity. I did all six cells and they averaged around 1,500 mAh. You can see the battery model numbers, but good luck finding the specs for these online. I found a used cell supplier that rated these at 2,000 mAh. Mine were still so new that I think I am right at the 1,500 spec. I tested other cells I had with consistent results, so I think my testers are working just fine.I still need to contact Amazon about these shady listings. There is no way any of these claiming 6,000 mAh when a single set of cells joined in series can be this. The description on this battery pack says, "Capacity: 6000mAh（No Fake High Label Capacity." This pack came from the POWTREE Store. It is completely FAKE!I'm not an electrical engineer, I just taught computers and also wanted to repair my bad DeWalt and Ridgid battery packs (yes, I know Ridgid has a warranty, and I've used it). But this kind of thing really ticks me off. My advice is to not buy any of these compatible Dyson replacement battery packs that advertise anything over 3,500 mAh. They are just not honest.

Yes, I have an older rechargeable Dyson v7 that did not hold its charge. This battery worked great, charges & holds its charge nicely. I've had it about a month & it has served me well.

This battery is malfunctioning after having it just over two months. This is the second of these batteries that I have had. The first one went dead within a short amount of time and I was able to receive this 2nd one free of charge. But now it doesn't work. Waste of time and money.

I am not satisfied with this battery. I ordered it April 2024 and as of today January 13,2025 it does not hold a charge. I live in a small apartment so it’s not like it’s being used every day in a large house. So was it a refurbished battery? Not that I was told but sure acts like it.

After a few weeks, this replacement battery holds more charge and longer than original battery. (Dyson really screws customers with its feable original batteries, and the handheld itself is not the wonder it's cracked up to be -- completely overrated)!

Buyer beware. The battery worked for about 2 months and then failed. It failed to charge and all we got was blinking red light. The posted information indicates there is a 1 year warranty but there is no contact information available or return address information. All we could find for the company on Google was a location in China. We had to call Amazon and will have to pay $7 to return it via UPS. In short, a very negative experience. Poor quality and unacceptable customer service from the product supplier!

I have an older Dyson V7 that I love to use for quick vacuuming around the house in between my deep cleaning. Unfortunately it died and I was so upset especially since these vacuums are not cheap and replacing it would have been a total bummer. My husband got this battery and put it in for me. Now it is working better than it did before. I can vacuum for a longer period before re-charging and it seems to have a lot more suction power. I hope this battery lasts as long as the original one did. It lasted for 6+ years! For now I am extremely relieved we got our vacuum working again! I love this battery!
