EFFEKTA® batteries, BT series EFFEKTA®, with its many years of experience with emergency power and UPS systems, guarantees that EFFEKTA® batteries deliver optimum quality and reliability. EFFEKTA® batteries are modern AGM batteries (Absorbent Glass Mat). The electrolyte is bound in a fibreglass mat, resulting in low self-discharge.
