Home > Alkaline Drain Chart

Alkaline Drain Chart

This chart shows how quickly the capacity of an alkaline battery drops as the load increases. Since a digital camera has a power drain of 0.75 to 1.25 watts the chart indicates that a AA alkaline battery rated at nearly 3000 mAh will deliver less than 700 mAh under the load of a digital camera.
