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.
