Capacity
Capacity of an alkaline battery is greater than an equal size Leclanché cell or zinc-chloride cell because the manganese dioxide is purer and denser, and space taken up by internal components such as electrodes is less. An alkaline cell can provide between three and five times capacity.
The capacity of an alkaline battery is strongly dependent on the load. An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. The voltage of the battery declines steadily during use, so the total usable capacity depends on the cut-off voltage of the application. Unlike Leclanche cells, the alkaline cell delivers about as much capacity on intermittent or continuous light loads. On a heavy load, capacity is reduced on continuous discharge compared with intermittent discharge, but the reduction is less than for Leclanche cells.

Famous quotes containing the word capacity:
“There is only one honest impulse at the bottom of Puritanism, and that is the impulse to punish the man with a superior capacity for happiness—to bring him down to the miserable level of “good” men i.e., of stupid, cowardly and chronically unhappy men.”
—H.L. (Henry Lewis)
“Managing a tantrum involves nothing less than the formation of character. Even the parent’s capacity to cope well with conflict can improve with this experience. When a parent knows he is right and does not give in for the sake of temporary peace, everybody wins. The parent learns that denying some pleasure does not create a neurotic child and the child learns that she can survive momentary frustration.”
—Alicia F. Lieberman (20th century)
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
