The NX300 Battery is the heart of Numatic’s cordless range - smart, tough, and engineered for serious runtime.
The Numatic NX300 lithium-ion battery delivers 300Wh of reliable cordless power across the entire NX platform - from Henry cordless vacs to wet extractors and compact scrubbers. Whether you’re detailing in a mobile setup or using cordless gear in a studio, this is the battery that keeps your Numatic gear working longer and harder.
It’s based on a 30-cell lithium layout that pushes 60% more energy than older battery designs. The NX300 is rated for 2,500 full charge cycles - and with the NX Fast Charger, you can hit 80% in just 60 minutes. Fully charged? That’s only 2 hours total.
Compatible with previous-generation cordless car vacuum cleaners like the Henry NBV190NX and RSB150NX RucSac vac, this battery keeps your setup cordless, simple, and ready to work - all backed by Numatic’s 3-year battery warranty.
