    The classical deficiencies of the lead-acid system which lead to eventual failure are examined from a structural engineering perspective. The fundamental low tensile strength of lead in conjunction with the formation of oxide films as it relates to the creep of the metal and the resultant growth of the positive electrode is discussed. The high mass of lead combined with its low tensile strength re... View full abstract»

    There is a growing trend among users of lead acid batteries towards use of sealed maintenance free designs. These offer the user many advantages in freedom of battery placement, increased safety, battery size and weight, no need to water, and in some instances superior performance. In standby service, two battery types are rivalling the traditional flooded lead acid stationary battery. Both are se... View full abstract»

    Sealed lead acid batteries for standby applications are known with gel-technology as well as with adsorbed electrolyte (starved electrolyte system). Because of the use of Sb-free lead alloys with high hydrogen overvoltage, the electrolyte decomposition during charging is extremely low and becomes even lower during the battery-life because of an increasing oxygen-recombination. Therefore those batt... View full abstract»
