This professional-grade 16.8 volt rechargeable battery will run continuously for 4+ hours on a single charge and can be re-charged up to 2,000 times to give you an estimated 3-4 years of use. Identical to VP20A, compatible with VP200ES and VP300ES. HIGH PERFORMANCE, LOW MAINTENANCE: Unlike many other kinds of rechargeable batteries, our lithium-ion battery requires no priming equipment or scheduled cycling, meaning it's truly "plug 'n play" with very little maintenance necessary. It can handle the rigors of repetitive charging and discharging unlike other batteries which can lose up to 30% or more of charge retention, even in high-powered applications. DURABLE YET LIGHTWEIGHT: Lithium-ion is the lightest battery kind available, yet is able to hold almost 2x the amount of energy as a nickel-based battery. Combined with the EvaClean Protexus sprayer's less than 4 lbs of handheld weight, we've ventured to reduce arm fatigue so your team can effortlessly focus on the task at hand. WHY PROTEXUS?: Cordless electrostatic spraying technology brings new 360-degree touchless cleaning capabilities to cleaning teams across all industries. The electrostatic charge of the sprayer allows the droplets to attract to the surface rather than float in the air, as is typically associated with a mister or fogger, nearly eliminating safety concerns for acute or long-term worker exposure by comparison. NEXT GENERATION SOLUTIONS: Gone are the long cleaning schedules, harsh chemicals, and bulky products. With the most powerful and reliable charge available, the EvaClean Protexus Handheld Electrostatic Sprayer is a way to build a safer, healthier world at a lower cost. At the end of the day, we're not working just to keep spaces clean - we're working to protect and save lives. You want the most reliable and powerful charge possible!
