There are no dumb questions only dumb bashers that answer your questions: Here's a table of energy densities you can see that Zinc Air rates very high: Battery System Anode Cathode Nominal Voltage, V Energy Density Wh/kg Energy Density Wh/L Leclanche Zn MnO2 1.5 85 165 Alkaline-MnO2 Zn MnO2 1.5 125 330 Zinc-air Zn O2 (Air) 1.5 340 1050 Li/SO2 Li SO2 3.0 260 415 Li/SOCl2 Li SOCl2 3.6 320 700 Li/MnO2 Li MnO2 3.0 230 550 It should be noted that as long as the relative humidity is around between 20 and 60% the opened battery will retain between 58 and 82% of its rated capacity after 30 days of exposure to the air. I believe that a simple piece of sealing tape that can re-used multiple times can extend the life of the opened battery by several times that if the opened battery is going to be idle for some time. EFCX may include such sealing tape in an elegant (design wise) way in the future. I believe foreign companies are under the same reporting requirements for listing on the major exchanges as are domestic companies.
