SGL / SGH GroE

Applications and Key Benefits

   - 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

          • Switchgear

          • Signaling and emergency lighting

          • IT datacenters

          • Starter batteries for diesel generators

   - 25 years 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

Applicable Standards

   - DIN 40738 - specification GroE cells

   - IEC 60896 part 11 - vented types requirements & tests

   - BS 6290 part 2 - British Standard Planté specification

   - UK National Grid (with optional nut & bolt terminals)

FIAMM Manufacturing

  - ISO 9001 Quality Management System

  - ISO 14001 Environmental Management System

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

   - Flame retardant lids are optional

   - Tin plated solid copper inter-cell connectors are fixed with an insulated screw
     with probe hole 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
