SATER service centre in Riga rebuilds cordless vacuum batteries for all popular brands — Dyson V6 through V15, Bosch Unlimited, Samsung Jet, Xiaomi, Philips SpeedPro, Electrolux Pure F9 and Rowenta X-Force. Cordless vacuum batteries are among the most heavily stressed household battery types: they discharge at high current, operate at elevated temperatures and are often fully drained with every use. As a result their lifespan is relatively short — typically 2–3 years, after which run time drops noticeably. At our service centre we completely rebuild the battery pack, replacing all cells with new high-quality SONY, SAMSUNG, MOLICEL or PANASONIC lithium-ion cells and fitting a fresh BMS board. The result often exceeds the original factory capacity. All battery work carries a 6-month warranty. Visit us in person at Silmaču iela 6, Riga, LV-1012 — we run diagnostics on the spot. Call +371 67377002. We do not ship or accept shipments by post — in-person drop-off only. Serving customers since 1993.

Dyson and cordless vacuum battery cell chemistry explained
Cordless vacuums, especially Dyson models, use high-drain lithium-ion cells capable of delivering large amounts of power in a short time. The Dyson V6 and V7 use a 21.6 V configuration with six cells in series (6S), while the latest V10, V11 and V15 use a seven-cell configuration (7S) with a total voltage of 25.2 V. These cells operate at high discharge currents — up to 20–25 A in max power mode — which accelerates their degradation.
The Bosch Unlimited series uses 18 V or 25.2 V configurations depending on the model, the Samsung Jet runs 21.6 V with six cells, and the Xiaomi G-series and Philips SpeedPro use 25.2 V. Regardless of brand or voltage, all of these batteries suffer from the same problem: after 300–500 full cycles at high current the cells lose a significant portion of their capacity. SATER rebuilds these packs using latest-generation high-drain cells from SONY, SAMSUNG and MOLICEL that deliver both high capacity and the ability to withstand heavy discharge currents without excessive heating.
Bosch, Samsung, Xiaomi battery rebuild service
In addition to Dyson models, SATER service centre in Riga rebuilds batteries for Bosch Unlimited, Samsung Jet, Xiaomi Mi Vacuum Cleaner, Philips SpeedPro, Electrolux Pure F9 and Rowenta X-Force cordless vacuums. Each brand has its own cell configuration and BMS board specifics, which we strictly follow during the rebuild process.
Bosch Unlimited 18 V batteries use a 5S configuration, while 25.2 V models use 7S. Samsung Jet packs are typically 6S at 21.6 V. Xiaomi G-series vacuums run on 25.2 V packs in a 7S layout. In every case we fully disassemble the battery, replace all cells with new high-drain SONY, SAMSUNG or MOLICEL cells, fit a fresh BMS board and run a complete charge-discharge test. This process ensures the rebuilt battery matches or exceeds the factory capacity. We have been doing this since 1993 — over 30 years of expertise rooted in the heritage of the Soviet-era Elektrons factory. All work carries a 6-month warranty.
