Abstract:
A button-type battery was designed for elec. and electroinc watches. The cells of RW44 size with a 0.450 in. diam. cathode container and from 0.150 to 0.162 in. high used a 40% KOH + 1% ZnO electrolyte soln. with a Zn gel anode and a seperator comprising an adsorbebt(webril) and a barrier material of polyethylene grafted with methacrylic acid between layers of cellophane. The divalent silver oxide depolarizer was 50-90% AgO, 1% Teflon, and the remainder Ag2O.
Abstract:
A battery charging apparatus wherein direct current voltage is applied to the battery to be charged through a controllable switch. The battery charger combines quick charge capability with long battery life. The battery charger charges the battery to a high potential in order to charge the battery quickly to full charge and after full charge is obtained maintains the battery at a low voltage in order to avoid damage and obtain maximum life.
Abstract:
A sealed low drain rate dry cell having an electronegative metal anode, a metal hydroxide electrolyte and in situ stable divalent silver oxide depolarizer.
