Calculator batteries have to meet a large number of design objectives, including:
Fortunately, battery manufacturers have refined calculator batteries to meet all of these demands. Early calculators used alkaline batteries, that had a high risk of leaking when not used for a while, possibly even destroying the calculator. More recently, silver oxide batteries were used because they provided more power in a smaller space, and both a constant voltage and long shelf life. Most current calculators run on lithium coin cells, because lithium batteries have all of the advantages of silver oxide batteries, but can provide more power with a higher voltage.
