By combining the service life reliability of a flooded battery with the performance energy density of a valve-regulated battery, BSB created the real true long service life battery – the LSE range. The range offers 20 years design life and a cycle life of 1000 cycles to 80% DOD according to IEC896-2. This range of battery is highly suitable for telecom, UPS, renewable energy system and power station etc.
