Electrical Characteristics of Saft LSH 20 Lithium Battery

(Typical values relative to cells stored for one year or less at +30°C max.)

• Nominal Capacity: 11 Ah (under 100 mA at +85°C, 2.0 V cut-off. The capacity restored by the cell varies according to current drain, temperature, and cut-off).
• Open Circuit Voltage (at +20°C): 3.67 V.
• Nominal Voltage: 3.6 V (under 3 mA at +85°C).
• Nominal Energy: 39.6 Wh (at +85°C).
• Pulse Capability: Typically up to 3000 mA. (The voltage 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. Consult Saft.
• Maximum Recommended Continuous Cu¹³rrent: 1000 mA (at +85°C, to maintain cell heating within safe limits. Battery packs may imply a lower level of maximum current and may request specific thermal protection. Consult Saft).
• Operating Temperature Range: -60°C to +85°C (-76°F to +185°F). (Higher temperature possible. Battery packs may imply lower maximum current and may require specific thermal protection. Consult Saft).

Storage

• Storage Environment: The storage area should be clean, cool (preferably not exceeding +30°C / +86°F), dry, and ventilated.¹⁵ For more severe conditions, consult Saft.

Warning

Fire, explosion, and burn hazard.

• Do not recharge, short circuit, crush, disassemble, incinerate, or expose contents to water.
• Do not heat above 125°C (257°F).
• Do not solder directly to the cell (use tabbed cell versions instead).
