The development of stationary sealed lead-acid battery with new electrolyte retaining method

The features of the Hipac Super-DX stationary sealed lead-acid battery are discussed, with particular emphasis on the electrolyte retaining method. To suppress the stratification of the electrolyte in stationary sealed lead-acid batteries, the authors have developed an electrolyte retainer mainly composed of fine inorganic powder and minute glass fibers. It has been demonstrated that the stratification of the electrolyte due to repeated charging and discharging of the battery is inhibited and that reduction in capacity is adequately prevented. It has also been confirmed that this novel design permits the construction of long, thin compact batteries which allow considerable saving of space.<>
