D Battery Duracell

The largest standard alkaline cell, holding several times the energy of an AA at the same 1.5 volts. Used where run time matters more than size: large torches, lanterns, emergency equipment and devices that must operate for extended periods without attention. Branded quality matters particularly here, since D cells often sit installed for years in emergency equipment. Highest capacity of the standard alkaline sizes; Very long run time in high drain devices; Branded alkaline resists leaking over long installation; Suits emergency and standby equipment
