Batteries:
For 10-Elements, the mid-size Copper-Zinc 6-Element should cost Thlr. 16.70 (Fl. 29.23) or Fl. 2.9225 (USD$ 1.22) per element. 

For 10-Elements, the mid-size Platinum-Zinc 6-Element (24 Quadratzoll) should likewise cost Thlr. 65. (Fl. 113.75) or Fl. 11.375 (USD$ 4.74) per element, a Platinum sheet ~11 Sq. In. (7.25 in. x 1.50 in. = ~70.2 cm²) with 22 Sq. In. (~140.4 cm²) surface area.







A study by Prof. Carl Kuhn of München, where 1 Element (Grove's type Platinum-Zinc Battery) costing Fl. 12./Thlr 6.86 with a Platinum Foil of 12-Quadratzoll (71 cm² or 11.00 in² and 22 in² surface) ; Fl. 12 = USD$ 5.

Assuming 24 Quadratzoll (Bavaria) = 22 in² double-sided surface area, equivalent batteries in different materials should reveal the cost per in² of Platinum Foil.  (In Berlin, for the 10-Element as described, the Platinum would have a marginal cost of Fl. 85, rather than Fl. 95 as Kuhn states.)

Eine Platinzinkbatterie aus 10 Elementen zusammengefaßt kostet, wenn jede Platinplatte etwa 24 Quadratzoll Oberfläche hat, gegen 120 Gulden; eine solche Batterie, wobei die Oberfläche der Platinplatte jeden Elementes etwa 16 bis 18 Quadratzoll hat wird um den Preis von 80 Gulden hergestellt (87) während eine aus 10 Elementen zusammengefaßt Kupferzinkbatterie nach meiner Einrichtung kaum 25 Gulden, eine Kohlenzinkbatterie unter denselben Umständen etwa um die Hälfte mehr kostet, und die Unterhaltungskosten einer Kohlenzinkbatterie, wie auch einer Platinzinkbatterie höher sind, als die der Kupferzinkbatterie. Aus diesen und noch manchen anderen Gründen möchte die Kupferzinkbatterie für die vorliegenden Zwecke in der Praxis die vortheilhafteste Kette sehn.


A Platinum-Zinc battery of 10 combined elements costs, if the platinum plate has about 141.974 cm² surface, Fl. 120.; another such battery, wherein the surface of the platinum plate each element has approximately 94.65 - 106.5 cm² surface, is made at for of Fl. 80 (87) whereas a 10-element combined copper-zinc battery for my device hardly costs Fl. 25, in the same circumstances a carbon-zinc battery  costs more by about half, and the maintenance costs of a carbon-zinc battery, as well as a platinum zinc battery is higher than that of copper-zinc battery. For these and many other reasons, the copper-zinc battery should be seen for present purposes in practice as the most advantageous in the series.

William Sturgeon's Fifth Memoir was composed in 1839, so his prices must date from that year. As a Grove's Battery of 10 Elements cost £ 7.0, a single Grove's Element cost £ 0.70 w/ 1 o.5"x 4" = 2" Sq. Foil. Where 50 pairs Platinum Plates 4"(o.5"x 4" = 2" Sq., double-sided = 4" Sq.) = 100 Sq.
