Zinc-carbon and alkaline primary batteries - a comparison of performance and cost
A comprehensive evaluation of the discharge lifetimes of popular brands of zinc-carbon and alkaline manganese primary batteries widely available on the UK market, is described. Samples of products were compared on various International Electrotechnical Commission standard discharge schedules, IEC 86 (1982), typical of their end uses in applications such as transistor radios, hand torches, tape cassette players and children's toys. Significant differences in the discharge performance were evident. The long-life' alkaline manganese formulations always gave the longest discharge durations. However, when cost was also considered and the batteries were compared on the basis of hours of service provided for each unit of purchase price, the zinc-carbon products were often a much better buy.
