The HRESYS DF (Duration Front) series VRLA batteries is especially designed for telecommunication
with 12+ years float design life. By combining the newlydeveloped paste formula with up-to-date AGM
structures, the series meet latest IEC, British and Telcordia standards. Front Access connection and
centralized venting system of DF series for fast, safety installation and maintenance.
-12 years long float life design
-Increased recharge efficiency due to advanced pasting formula
-International Standards Compliance, i.e. IEC, EN, BS, CE etc
-Batteries are mainly working at standby status but also for cyclic use with not very frequent cycles
-Long cycle life thanks to thick plates with Tin Calcium alloy
-Front Access Terminal design easy for inter-block connection
-Low self-discharge rate enables long shelf life
-Batteries are normally installed in standard 19” and 23” cabinet
-Wide temperature range operating between -20°C and +60°C
-Excellent high rate discharge performance -Cross-wall welding between each cell, this construction
made internal resistance very low -Superior grid radiates style design; raise the high rate discharge
performance. -Patent paste technology -Copper core cable, copper bar as optional
