Leifheit – battery regeneration for cordless vacuum cleaners

German precision in everyday living

Leifheit is a name synonymous with quality, functionality and refined simplicity. Since its foundation in the 1950s, the brand has stood for durable household products designed to make everyday tasks easier and more efficient. Its cordless vacuum cleaners embody the same principles – reliability, thoughtful engineering and elegant design. Each model reflects the essence of German craftsmanship: quiet operation, ergonomic comfort and technical perfection. Leifheit products are built to serve households that value cleanliness, practicality and timeless durability.

Restoring the original performance

Even the most advanced batteries lose capacity over time, leading to shorter runtime and weaker suction. When that happens, Regeneration Leifheit restores the battery’s power and efficiency to factory-level standards. The process begins with a complete diagnostic check of the cells and protection electronics. Worn components are replaced with new branded cells from leading manufacturers such as Panasonic, Samsung and Sanyo. This ensures stable voltage, balanced power delivery and long-term durability. Once reassembled and calibrated, the battery regains its strength, allowing the vacuum cleaner to work with renewed consistency and endurance.

Expertise built on experience

The regeneration process is carried out by specialists with more than fourteen years of experience in servicing lithium-ion batteries. Using professional cell-welding equipment, they create solid, low-resistance connections that ensure reliable current flow. Every regenerated battery undergoes extensive load testing to confirm safety and performance under real conditions. After passing final inspection, it is shipped promptly back to the customer, minimizing downtime and allowing the device to return quickly to regular use. The combination of advanced equipment, craftsmanship and strict quality control defines the durability that Leifheit has represented for decades.

Durability meets responsibility

For Leifheit, true innovation lies in creating solutions that last. Regeneration Leifheit follows this philosophy by extending the life of existing equipment and reducing electronic waste. Instead of replacing an entire vacuum, the regeneration process renews the power source, maintaining the familiar comfort and efficiency users expect. It’s a practical and environmentally responsible approach that reflects the spirit of sustainable German design – one that values quality, reliability and respect for resources. With regenerated batteries, Leifheit continues its mission to combine technology and tradition in the service of everyday comfort.
