Abstract :
A large capacity, float charged stationary lead acid cell designed to provide maximum electrical performance per square foot of floor space for a given height, superior sealing, minimum maintenance and optimum safety that meets the battery energy requirements for the next decade. Unique design features include a transparent jar that is self-extinguishing, a permanent thermal fusion jar-cover seal, a post seal that effectively stops acid creepage, the option of either lead antimony or lead calcium grids and the ability to handle both short and long duration service or a combination thereof. The introduction of the new cell had to be integrated with the start-up of a new manufacturing plant. This meant that design requirements had to be defined to the extent that production machinery could be ordered 24 months in advance of prototype production. The cell also had to be compatible with three different markets -- utility switchgear, uninterruptible power system and telecommunications -- and be flexible enough to meet future individual requirements of particular customers within each market segment. (For example, those of the Bell System and those of the hundreds of independent telephone companies worldwide.)
