There have been major improvements in alkaline cell performance over the decades. These improvements have been a result of changes in packaging and manufacturing techniques rather than any improvements to the basic chemical system.

In the past, alkaline batteries were made with complex sealing systems and thick steel outer cases and end caps. During the 1980s, a method was developed that allowed manufacturers to use thinner packaging materials and more efficient seals. More room was created for active materials within a given standard cell size, and that increased capacity.

In the early 90s, government mandate ruled out the use of mercury in alkaline cells providing a major challenge to manufacturers. Mercury, an environmental pollutant, was used in alkaline batteries as an anti-passivation stabilizer for the zinc electrode. Without mercury, chemical processes within the battery cause the zinc to function less efficiently as discharge proceeds because of passivation of zinc surface, thus limiting useful battery life.

Battery Manufacturers, such as Energizer and Duracell rose to the challenge and we now have mercury free cells that function as well as their predecessors. They provide excellent performance at a price premium for applications such as toys, radios, and flashlights. Brand name recognition, i.e. Energizer and Duracell, make this chemistry an excellent choice when product image is important.
