Alkaline cells are 1.5 volts (nominal) and range between 34 to 17,000 mAh in capacity. The recommended discharge drain is from 620 to 39 ohms. The energy density by weight is 75 Wh/lb (163 Wh/kg) and by volume is 6.5 Wh/cubic inch (398 Wh/litre). There is a 5-year shelf life to 80% capacity at 20 degrees C. The operational temperature range is from -20 degrees C to +55 degrees C.

Common applications for the alkaline batteries are portable consumer electronics, flashlights, and other high-drain primary battery applications.
