Advantages Immediately ready for use and maintenance-free, Saft air-depolarized batteries offer: complete operational autonomy maximum autonomous energy density good resistance to extreme climatic conditions long operational and storage life easy installation, use and replacement excellent cost-efficiency very high reliability. Saline batteries Saft saline batteries are particularly suitable for applications such as electric fences, lighthouses and buoys, parking meters, and rail signalling. Offering high energy density and stable voltage levels, they are ideal for all uses requiring low continuous discharge over long periods of time, and high instantaneous or pulse discharge. Saline batteries for electric fences Saline batteries Suitable for lighthouses and buoys, parking meters, railway signalling.

3 Gel alkaline batteries Saft gel alkaline batteries are especially suitable for rail signalling, road signage, lighthouses and buoys, etc. With their combination of very high energy density and a capacity for high continuous discharge, they are ideal for all uses requiring continuous high discharge, and high instantaneous or repeated discharge. Like saline batteries, Saft alkaline batteries can be used without any risk of leakage on fixed or moving installations requiring a high level of autonomy. Criteria for choosing air-depolarized batteries Voltage: minimum or maximum accepted. Current: continuous or pulse discharge. Maximum current required. Discharge profile. Operating and storage temperatures: ranges. Average value. Required capacity or lifetime: acceptable minimum. Storage life: maximum and minimum required. Must be stored and used in an upright position. Physical characteristics: dimensions. Volume. Weight. Adequate ventilation must be ensured. Saft and quality Saft produces electrochemical generators for civil and military applications. Our products must therefore meet the most stringent requirements for performance and reliability. Saft s quality programme is internationally recognized and certified. Highly exacting standards Saft s World Class 2000 programme involves all aspects of the business, from R&D and production through to administration and human resources. Saft s quality assurance system is certified AQ-F2 by SNCF and BS by the British Railway Board (BRB), and has also obtained parts and 2 of the United Kingdom BS 5750 certification. The division has achieved ISO 900 certification, awarded by the AFAQ. Respect for the environment Saft has introduced an environmental policy covering the entire battery life cycle, from design through to collection, sorting, end-of-life recycling and recovery of used materials. To ensure unfailing conformity to environmental procedures throughout the recycling process, Saft has signed long term contracts with specialized companies such as Zimaval and Screlec in France and Inmetco in the USA.

4 Saline batteries Recommended for all uses requiring continuous low discharge over very long periods, and/or high instantaneous or pulse discharge, air-depolarized saline batteries offer the key advantage of combining high energy density with stable voltage levels. Technology Saft saline batteries are based on a zinc-oxygen electrochemical couple. Depolarization is produced by atmospheric oxygen. The electrolyte is an aqueous gel solution of ammonium and zinc chloride. Advantages Saline batteries offer stable voltage levels, exceptional storage life, and high reliability. They provide high energy density: 40 Wh/kg and 50 Wh/dm 3 on average. Saft saline batteries require no maintenance and function satisfactorily at temperatures ranging from -5 C to +45 C. Variations in atmospheric humidity have no significant effect on their operating performance. Main applications Saft saline batteries are recommended for continuous low discharge (less than 0.2 Amps) and/or high instantaneous or pulse discharge applications. They are therefore particularly suited for: rail signalling emergency telephones on motorways parking meters lighthouses and buoys electric fences, etc. References AD 540 AD 535 AD 524 AD 57 AD 53 AD 6540 AD 6535 PRO PRO TURBO PRO PRO Physical characteristics Length (mm) Width (mm) Height (mm), including terminals Weight (kg) Nominal electrical characteristics Open circuit voltage (volts) Nominal capacity at c/5000 (Ah) Typical discharge Resistance (Ω) Duration (h) Maximum current (A) Continuous Intermittent Pulse Max. hourly capacity of intermittent or pulse discharges (Ah) Cut-off voltage: 0.8V per cell - Temperature: +20 C - Continuous discharge - 2 Discharge time less than min. - 3 Discharge time less than sec.

6 G el alkaline batteries Recommended for all uses requiring continuous high discharge, and high instantaneous or repeated discharge, air-depolarized gel alkaline batteries combine very high energy density with a capacity for high continuous discharge. Technology Saft gel alkaline batteries are based on a zinc-oxygen electrochemical couple, with atmospheric oxygen producing depolarization. Their characteristic feature is the large-surface-area zinc anode composed of zinc powder dispersed in a potassium gel solution. Advantages Gel alkaline batteries combine the advantages of saline batteries and of liquid electrolyte alkaline batteries. Like saline batteries, they can be used without any risk of leakage or of spillage when in movement. They require no maintenance and no special procedures before being ready to use. Saft gel alkaline batteries provide a very high energy density (260 Wh/kg and 300 Wh/dm on average) and have a capacity for high continuous discharge. They can be satisfactorily used at temperatures ranging from -30 C to +45 C. Variations in atmospheric humidity have no significant effect on their operating performance. Main applications Recommended in particular for continuous high discharge (up to.5 Amps per cell) and for high instantaneous or repeated discharge, Saft gel alkaline batteries are suited for: rail signalling applications in motion (e.g. train rear signal lamps) References AD 860 AD 840 AD 830 AD 80 AD 80 NA Physical characteristics Length (mm) Ø22 Ø22 Width (mm) Height (mm), including terminals Weight (kg) Nominal electrical characteristics Open circuit voltage (volts) Nominal capacity at c/5000 (Ah) Typical discharge Resistance (Ω) 8,5,5 0,7 0,7 Duration (h) Maximum current (A) Continuous Intermittent Pulse Max. hourly capacity of intermittent or pulse discharges (Ah) Cut-off voltage: 0.8V per cell - Temperature: +20 C - Continuous discharge - 2 Discharge time less than min. - 3 Discharge time less than sec.
