Abstract
A pressurized-gas battery, such as a nickel-hydrogen battery, is rapidly charged at a high charging rate until the measured pressure reaches a high-pressure limit, and thereafter slowly charged at a reduced charging rate as the measured pressure falls toward a low-pressure limit. The high-pressure limit and the low-pressure limit each decrease with increasing temperature.
