Our cutting-edge technology rejuvenates batteries without damaging them, reducing greenhouse gas emissions and avoiding the need for energy-intensive recycling. Lead-acid batteries are integral to battery backup systems in solar and wind farms, telecom towers, and data centres. They are also used widely in cars, forklifts, banks and ATM systems.
