Sealed lead-acid battery
EPL FTNG Series
Model: EPL 155 - 12 FTNG
EPL-FTNG series are batteries with over 12 years of the design life at 20°C - according to Eurobat (10 years at 25°C), made in the gel technology. They have front terminals and a special case construction that allows them to be mounted in 19” and 23” cabinets. The EPL FTNG series is equipped with a Central Degassing System, consisting of a small conduit which can lead the small amount of gas liberated during operation outside the sealed cabinet in which the batteries are installed. EPL FTNG batteries have repeatable parameters and excellent discharge characteristics and this is why they are very often and readily used for the standby use in important telecommunication systems. Owing to the gel technology they are very often used for outdoor systems prone to large operating temperature changes.
