The invention discloses a method for container formation of a lead-acid storage battery. The method comprises the following steps of: placing a lead-acid storage battery filled with electrolyte into a circulating water bath, cooling to 40 DEG C below, conducting charging and discharging, wherein the specific charging and discharging processes include eight charging processes and two discharging processes. According to the method, by adding a second-stage and a fifth-stage charging currents, the charging efficiency is improved, the container formation time of the battery is shortened, and the initial-stage capacity and recycling life of the battery can also be increased and prolonged, so that the method has great significances for the production of the storage battery.
