Lithium Coin Battery Safety. This is the basic series of alkaline batteries, it has five main sizes: AA, AAA, C, D - for one and a half volts, and also the Duracell Basic 9V battery (better known as Krone) - for 9 volts. At 500 mA discharge rate the Radio Shack and Duracell are neck and neck. Typical Volume: 8.0 cubic centimeters (0.49 cubic inch) American ruler. Duracell’s latest safety features help keep children safe. These batteries are freshness sealed with Duralock Power Preserve Technology that makes them perfect for long-term storage or emergencies with an extended shelf life! A cell doesn’t deliver a constant voltage. The Open Circuit Voltage (no load voltage) of the 1.5V AA Duracell Procell Alkaline batteries is 1.6V, though it quickly drops to 1.5V under load. Duracell is the #1 trusted battery brand, and we’re proud to offer you Duracell 1.5-Volt Optimum Alkaline AA batteries as part of Duracell’s trusted lineup of batteries. Since 2011, Duracell has brought its reliable power to thousands of families through the Duracell PowerForward program. I don't have the patience to run it at lower amp rates, but for very low discharge applications you might find that the Coppertop excels the Radio Shack even more. Duracell Duralock AA Powerful Alkaline Power The finest AA battery by Duracell. The M11R working voltage is 0.9~4.2volts and the battery extender is for AA and 14500 Li-Ion 3.7 volt rechargables , so you SAFT should be no problem. Let us consider in more detail the difference between these batteries. At a slow discharge rate the Duracell pulls out ahead slightly, both for the voltage and the amp hours. ! As an example, here’s a graph of the voltage of a “1.5 volt” alkaline cell – a fresh Duracell AA – with a constant 500 mA load: Duracell is the No.1 trusted battery brand, and we're proud to offer you Duracell 1.5-Volt Optimum Alkaline AA batteries as part of Duracell’s trusted lineup of batteries. Extra Life or Extra Power vs. Coppertop AA in a wide range of devices. I don't believe output is higher 230 lumens is still max If you use some lithium AA battery, for example Energizer L91 - they have much more energy "available" before voltage drop below 1.5 V, but be careful - they have also higher initial voltage (about 1.7 V) and they are expensive (in my country they cost 2-4x more than alkaline Energizer or Duracell). DURACELL PROFESSIONAL AA battery test @ 1000mA details: New battery voltage (no load applied) measured - 1.59V Battery test was stopped once voltage (under constant 1000mA load) dropped to - 0.8V During the test average battery temperature was 28.5C Under load battery internal resistance measured at 148mOmh Page 1 of 2 Nominal voltage 1.5 V Impedance 120 m-ohm @ 1 kHz Typical weight 24 g (0.8 oz) Typical volume 8.4 cm3 (0.5 in3) Terminals Flat Storage temperature range 5ºC to 30ºC (41ºF to 86ºF) Operating temperature range-20ºC to 54ºC (-4ºF to 130ºF) Designation IEC: LR6 This data is subject to change. The world's number one alkaline battery, Duracell Duralock AA are the perfect choice for use at home or work. AA Classification: "Cylindrical Primary Lithium" Chemical System: Lithium/Iron Disulfide (Li/FeS 2) Designation: ANSI 15-LF, IEC-FR14505 (FR6) Nominal Voltage: 1.5 Volts Sizing Compatibility Storage Temp:-40°C to 60°C (-40°F to 140°F) Operating Temp:-40°C to 60°C (-40°F to 140°F)* Typical Weight: 15 grams (0.5 oz.)
