I have been pleasantly surprised! I don’t remember the Dyson having ever been this powerful. I can now hoover the entire house, whereas the old battery had got to the point of managing either upstairs OR downstairs, but never both. Very pleased. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Seems goods value *by H***N on Reviewed in the United Kingdom on 26 October 2020* So far so good, I was sceptical about ordering a non Dyson branded battery, but given the price difference I decided to give it a go. Comparing old to new they look identical. Performance doesn’t seem to have been negatively effected. Hopefully I will get a good couple of years service from the battery. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect for the job *by C***L on Reviewed in the United Kingdom on 22 August 2020* I was a bit worried about buying a product that was not manufactured by the same company that made the vacuum cleaner I was using it with. I needn't have worried as it works perfectly and it only cost a fraction of the price of the more famous brand. --- ## 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.sk/products/93998491-opson-22-2v-2-5ah-li-ion-type-b-battery](https://www.desertcart.sk/products/93998491-opson-22-2v-2-5ah-li-ion-type-b-battery) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-22*
