True 2000mAh capacity
What makes our batteries different? When we state 2000mAh, that’s exactly what you get. Competitors often claim capacities for batteries that are in fact far, far lower. This battery has a true capacity of 2000mAh - exactly as advertised.
High-performance XBATR725SL battery
Our replacement Cordless Detect Pro, IW3511, IW3615 batteries deliver consistently high performance, power and suction, and runtimes that match or exceed that of your original vacuum cleaner battery - for a high number of charging cycles.
Superior quality and safety standards
Battery specialists since 2004, all our replacement batteries undergo strict and rigorous testing throughout the whole production process, complying with the highest standards and beyond. That’s why they come with a 3-year warranty.
The sustainable choice
Replace the battery, not your vacuum cleaner. It’s the smarter, cheaper, eco-friendlier choice, cutting your environmental footprint through recycling and reducing unnecessary waste.
