Sf Industrial Stan Tubular


  • More than 20% extra electrolyte which means lesser topping-up frequency and an unhindered performance
  • Better thermal management
  • Customised exclusively for inverters
  • Expected life - 2 year plus - under arduous condition
  • Easy maintenance
  • Special polythelene 'envelope' seperator reduces the probablity of internal short circuit, thus enhancing the servise life
