4600mAh capacity increases run time and peak power for V8 vacuums. Intelligent ECP protections and OEM-fit design ensure safe charging and simple installation.
Longer Cleaning Sessions – With 4600mAh battery capacity
4600mAh lithium-ion cells at 21.6V are engineered for the V8 series, delivering higher energy density and extended cycle life. Full charge yields around 50 minutes in normal mode and roughly 8 minutes at maximum power.
Extended runtimes let a single charge cover typical whole-house cleans, while short high-power bursts handle stubborn spots.
Safer, Reliable Charging – Thanks to intelligent ECP protection
An ECP chip guards against over-charging, short-circuit, high-temperature and over-current conditions, and the cells have no memory effect for flexible charging. The battery passed extensive ageing tests and holds CE, FCC and RoHS certifications.
Reduced risk of overheating and preserved capacity over many cycles, making frequent charging less worrying for everyday use.
Quick Swap and Cleaner Air – With OEM-fit design and bonus filters
Dimensions and connector layout match OEM V8 batteries for a simple installation that takes about two minutes, and the bundle includes two washable pre-filters plus a cleaning brush and screwdriver.
Fast, tool-assisted replacement gets the vacuum back to work quickly, while extra filters help trap pet dander and fine dust for cleaner exhaust air.
