Abstract A charged storage battery having good shelf life and activation performance characteristics upon the addition of electrolyte is made by forming the battery in the usual manner in forming electrolyte, permitting the formed plates to stand in the forming acid while boosting the plates with an electrical charge, removing the electrolyte from the formed storage battery, and filling the battery with water. The water can be left in the storage battery and the battery stored or shipped in this manner. In a preferred manner, the water is removed from the battery after standing in it for approximately 5 minutes to 1 hour, the negative plates are passivated by introducing oxygen into the storage battery, and then the battery is sealed, stored and/or shipped.
