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.

Temperature controlled, auto timed, variable amperage cascading-water

A method for producing batteries having plastic cases wherein a plurality of sets of batteries are placed in a plurality of portable tanks or tubs which are positioned at different heights above the floor and filled with water, filling the highest tub first and allowing it to overflow to fill the adjacent lower tub and so on until all tubs are filled and overflowing. Before the water is added to the tanks, electrolyte is added to unfilled, unformed batteries and a separate rectifier circuit is connected to each set of batteries for passing current therethrough to form or charge the batteries.
