I installed this one and it has been working great! ### ⭐⭐⭐⭐ Works great but lasted about 10 months *by D***N on Reviewed in the United States on December 31, 2022* This battery fit just as well as the original and it had similar capacity. After ten months the battery is starting to lose it's capacity and I'll have to replace it soon. We use the vacuum 2-3 times per week. I would liked for it to have lasted longer but I didn't have high expectations for a generic battery. ### ⭐⭐⭐⭐⭐ Company stands behind their product *by B***Z on Reviewed in the United States on January 6, 2021* I had originally submitted a poor review of this product because it appeared the battery was only holding a charge for a few seconds after I installed it. After my review was received the company immediately contacted me to offer me a refund or replacement. I appreciate your willingness to work with me on the replacement battery. I decided to further investigate the Dyson vacuum and discovered their was a large clog in the vacuum head that was the problem. I was able to thoroughly clean out the unit and have been able to use the vacuum again with no issues. The new battery I purchased from seems to working correctly now that the clog was removed. I appreciate the company reaching out to stand by their product and would recommend this replacement battery for the Dyson vacuum. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/182806762-kunlun-4-0ah-v7-battery-replacement-compatible-for-21-6v](https://www.desertcart.tw/products/182806762-kunlun-4-0ah-v7-battery-replacement-compatible-for-21-6v) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-25*
