Used by the world's leading companies, it enables very thin sheets to be produced and a larger quantity to be housed in a tray. The advantages: greater start-up power, better current conductivity, virtually zero self-discharge. Calcium/calcium technology also increases the number of cycles (discharge + charge) and eliminates water consumption.
