Trough battery spaces between the plates (the troughs) were filled with dilute sulfuric acid. So long as the box was not knocked about, there was no risk of electrolyte spillage. Trough battery The trough battery was a variant of Alessandro Volta's Voltaic Pile and was invented by William Cruickshank c. 1800. Volta's battery consisted of brine-soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Cruickshank solved this problem by laying the battery on its side in a rectangular box.
Who Killed the Electric Car? either unaware that an electric car was ever available to try, or dismayed that they could no longer obtain one. In a bit of an unexpected turn, the film's sole "not-guilty" suspect is batteries, one of the chief culprits if one were to ask the oil or auto industries. At the time GM's EV1 came to market, it came with a lead acid battery with a range of 60 miles. The film suggests that since the average driving distance of Americans in a day is 30 miles or less, for 90% of Americans, electric cars would work as a daily
