Abstract
A novel formation method is disclosed which is compatable for use in forming high antimony as well as, maintenance free (i.e., low antimony calcium, etc.) batteries. The method includes constant circulation of a cooling fluid around the batteries to be formed while the batteries are stepped through various charging cycles of different lengths and currents. The preferred method is a 'one shot' method, thus eliminating the necessity of adding successive electrolyte solutions to the batteries. Unlike prior 'one shot' formation techniques, however, formation times are relatively short while plate clearance characteristics and the completeness of formation are excellent.
