Industry-leading VRLA solution delivers more power, extended life, and superior reliability for critical UPS and energy storage applications.
GS Yuasa, the world’s leading battery manufacturer for over a century, announces the official launch of its new Yuasa SWL+ series. Building on the success and proven dependability of the renowned SWL range, the SWL+ series sets a new benchmark in VRLA (Valve Regulated Lead Acid) battery technology for high-rate discharge and standby power applications.
Aimed at the most demanding UPS (Uninterruptible Power Supply) and energy storage environments, the SWL+ series addresses growing market needs for longer-lasting, higher-performance energy solutions. From large-scale data centres and manufacturing facilities to towering city skyscrapers and landmark infrastructure, the new SWL+ provides the enhanced reliability these mission-critical operations demand.
At the heart of the SWL+ series is Hybrid Pure Lead technology—an advanced combination of primary pure lead and specialised recycled alloy. By incorporating a sustainable element alongside pure lead, this pioneering approach achieves increased corrosion resistance and extended battery life. The carefully balanced alloy composition further enables higher energy density—vital for high-rate discharge scenarios where every second counts. This unique blend sets the SWL+ range apart from competitors, delivering improved longevity and dependable power.
In tandem with this, the SWL+ series incorporates GS Yuasa’s exclusive HT Element X Alloy™, which dramatically reduces positive grid corrosion and water loss in high-temperature conditions. Combined, these innovations offer robust performance, improved longevity, and dependable power in even the most challenging operational environments. Additionally, it enables energy cost savings—for example, maintaining an ambient temperature of 25°C in battery rooms still ensures a 12-year design life, reducing the need for more intensive (and expensive) cooling.
Their extended15 year design life not only reduces replacement frequency but also delivers significant CAPEX advantages by lowering long-term investment costs.
