FT Series
FT (Front Terminal) Series is specially designed for telecom use with 12 years design life in float service.
By adopting a new AGM separator and centralised venting system, the battery can be installed in any position
while maintaining high reliability. The dimensions of the FT series is designed for 19" and 23" cabinet installation.
