Sealed Lead Acid Batteries

12V 40AH Sealed Lead Acid Battery


LY11-059-28

  • The 'Online' range of sealed lead acid batteries are maintenance free, valve regulated and leak proof ideally suited to all 'standby applications'
  • There will be no loss in power output over the battery life.
  • Low self-discharge of about 2-3% per month compared with 20-30% for more common battery systems.
  • Quality construction with no compromise on materials to ensure a long service life.
  • Low internal resistance means a high discharge rate.
  • Wide operating temperature range operating between -15° C to +50 ° C when fully charged.
