MAINTENANCE-FREE LEAD ACID BATTERIES.
Abstract
An evaluation program on maintenance-free lead-acid batteries was conducted at the US Army Electronics Command for the purpose of determining the feasibility of replacing some of the more expensive nickel-cadmium batteries in the field. With the elimination of troublesome water makeup along with the employment of new state-of-the-art electrode designs, which feature long life and efficient high rate discharge capabilities, the familiar lead-acid battery has become attractive as a high capacity, long life battery with low user cost. Environmental testing has been completed. This battery, with lead-calcium grids, will retain 70% of its initial capacity after storage at 125F for 30 days. A cycle life of 200 cycles at 80% depth of discharge was demonstrated, no water makeup being required during cycling. (Author)
