Home > Product & Solutions > LSE Series – 2V AGM Battery

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.

Features and Benefits

  • 20 years design life at floating condition at 20°C
  • Wide temperature range from -15 to 55°C
  • High integrity, dual pillar seal design
  • Low float current designs paste enable significant electrical cost saving
  • Thick positive flat plate design with high Tin low Ca alloy
  • Low self-discharge rate and long shelf life( 1 year at 25°C)
  • High gas recombination efficiency as high as 99.9%

Construction

  • Positive plates – Thick high Sn low Ca grids to resist corrosion and prolong life
  • Negative plates – Balanced lead-calcium grids for improve recombination efficiency
  • Separators – Advanced AGM separators for ultra low float current
