- High voltage response, stable during most of the lifetime of the application 

- Wide operating temperature range (-60°C / + 85°C) 

- Low self-discharge compatible with long operating life (less than 1% after 1 year of storage at + 20°C) 

- Superior resistance to corrosion 

- Low magnetic signature 

- Bobbin construction 

- Well controlled passivation 

- Hermetic construction with glass-tometal seal 

- Stainless steel can 

- Non-flammable electrolyte 

- RoHS and REACH compliance 

- Made in France

- 1Typical values relative to cells stored up to one year at + 30°C max. 

- 2Sleeved cell. 

- 3Dependent upon current drain, temperature, cut-off and cell orientation. 

4Under 300 mA / 0.1 second pulses, drained every 2 minutes at + 20°C from undischarged cells during 24 h, with 10 µA base current, yield voltage readings above 3.0 V after initial stabilisation. The readings may vary according to the pulse characteristics, the temperature, and the cell’s previous history. Fitting the cell with a capacitor may be recommended in severe conditions or for high pulse currents. Consult Saft. 

5Operation above ambient temperature may lead to reduced capacity and lower voltage readings. Consult Saft. 

- 6For more severe conditions, consult Saft.

- The storage area should be clean, cool (preferably not exceeding +30°C), dry and ventilated. 

- Fire, explosion and burn hazard. 

- Do not recharge, short circuit, crush, disassemble, heat above 100°C (212°F), incinerate, or expose contents to water. 

- Do not solder directly to the cell (use tabbed cell versions instead). 

- Do not remove the cells from their original packing before use. 

- Do not store the cells in bulk to avoid accidental short circuiting. 

- Do not mix new and used cells or cells from different origins. 

- Mind the polarities of the cell.
