CTL series batteries are maintenance-free lead batteries of a mesh mat design (AGM technology). According to EUROBAT, the batteries in the CT series have a lifespan of 6-9 years, whereas CTL series batteries boast a 10-12 year lifespan. Both series are subject to strict quality assessment. They are produced in state-of-the-art facilities and there is minimal variation in their performance parameters. Because of their performance characteristics, batteries of this series are ideally suited for use in UPS systems.
