FIAMM Endurlite SGL / SGH GroE

Technical specification

Capacity
79 – 2860 Ah

Nominal voltage
2 V DC

Expected operating life
25 years

Designed for highest reliability in standby mode, for high performance, high current and deep discharge applications.

Ideal for:

  • Nuclear and thermal power plants
  • Electrical utilities
  • Power supply units for substations
  • Switchboards
  • Signaling and emergency lighting
  • IT datacenters
  • Starter batteries for diesel generators

Applications and key benefits

  • 25 year design life in float operation in temperature controlled environments.
  • 100% rated capacity throughout the battery life. No requirement to oversize the battery.
  • Excellent for high current discharge (1 to 60 min) and medium to long discharge (2 to 8 hours).
  • Long life even in the worst operating conditions.
  • Extra thick pure lead Planté plates.
  • High reliability post seal.
  • Extremely long topping-up intervals.
  • 100% recyclable

Technical features

  • Positive GroE (Planté) plates, cast from pure lead to avoid capacity drop during the long battery life.
  • Negative plates with rugged pasted grid construction with a service life compatible with the positive plates. The alloy and curing process are designed to maintain the porosity of the active material during operation.
  • High purity sulphuric electrolyte with a very low specific gravity of 1.22 (±0.01) at 20°C.
  • Microporous separators maximize electrolyte utilization, minimize resistance and guarantee lowest self-discharge.
  • Cell containers are injection molded from high quality transparent SAN (styrene acrylonitrile) for easy cell status inspection.
  • Lids made of opaque ABS.
  • Female threaded M10 terminals and pillars with solid brass inserts ensure highest conductivity and perfect contact (Optional nut and bolt type terminals with copper inserts).
  • High integrity post seal design to avoid electrolyte leakage and terminal corrosion.
  • Vent plugs effectively return acid spray to the cell under normal operating conditions of float and boost charging. The vent plugs have a ceramic filter and bayonet lock, designed to prevent any errant spark or flame from entering the cell.
  • Dedicated service hole allows topping-up without removal of the vent plug.
  • Flame retardant lids are optional.
  • Flexible, fully insulated cable connectors with insulated screw with probe hole on the top for electrical measurement.
  • External recombination plugs optionally available.
  • < 3% self-discharge per month at 20°C allows 4 months shelf life.
  • Optional seismic racks UBC zone 4.
