Not an official Dyson product – This battery is third-party and not manufactured or endorsed by Dyson. It might technically affect warranty coverage, though in practice, it’s unlikely Dyson could verify or enforce that — especially once the battery is already installed.

No documentation or identifiable branding – The battery arrived in a plain cardboard box, without any manual, branding, or instructions. I purchased it from a store with strong feedback, which gave me confidence — but aside from a small sticker on the battery, there’s no clear product information. That’s something to be aware of, especially with products like batteries that must meet safety standards.

Some third-party batteries advertise better price-to-capacity ratios – While searching for a replacement battery, I came across many non-original brands — often unfamiliar — offering significantly larger advertised capacities at similar prices. On paper, these seemed like better value for money, but I had concerns about actual performance, added weight, and long-term reliability. It’s something worth exploring, but with caution.
