A New Manufacturing Method for Lead-Acid Storage Batteries 720041

A new process for the preparation of lead-acid batteries has been developed in response to problems associated with inventory maintenance of wet batteries and the processing and performance of dry charge batteries. Unique steps are a modified formation treatment followed by removal of most of the electrolyte by the use of an accelerative force, such as that generated by a centrifuge, to produce a charged and tested finished battery in a moist condition. The new product has superior properties that enable the manufacturer to store and activate it within the battery plant to service the wet battery market or to ship it to the dry charge market as a high-performance long-shelf-life product.
