Please note these are Primary batteries, which mean they are NOT RECHARGEABLE. NEVER attempt to charge them. Please note that these batteries might look slightly different than shown in the pictures. Saft occasionally changes the look of their batteries. But, it will always be 100% genuine Saft batteries, with the specified specifications and part number. Specifications: Type: 1/2 AA Size, Non Rechargeable Battery Open circuit voltage: (at 20°C) 3.67 V Nominal voltage: (at 0.1 mA 20°C) 3.6 V Nominal energy: 4.32 Wh Pulse capability: Typically up to 100 mA (100 mA/0.1 second pulses, drained every 2 mn at 20°C from undischarged cells with 10 μA base current, yield voltage readings above 3.0 V. 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. Consult Saft) Maximum recommended continuous current: 35 mA (Higher currents are possible, consult Saft) Storage: (recommended) 30°C ( 86°F) max (for more severe conditions, consult Saft) Operating temperature range: -60°C/ 85°C (Operation above ambient T may lead to reduced capacity and (-76°F/ 185°F) lower voltage readings at the beginning of pulses. Consult Saft) Diameter: (max) 14.55 mm (0.57 in) Height: (max) 25.15 mm (0.99 in) Typical weight: 8.9 g (0.3 oz) Usage & Precautions IMPORTANT These are very powerful batteries, and extreme care should be taken using them. Ensure to never short positive and negative terminal of the battery In worst case Lithium batteries can explode or catch fire when used improperly Use at your own risk. There are battery holders and covers to keep your batteries safe. Do not dispose any battery in a fire There are dangerous chemicals in batteries. If you try to burn your batteries they’ll release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling center.
