Stationary Valve Regulated Sealed Lead-Acid Batteries can the Arrhenius Equation be used to Predict Product Life

Some high temperature tests have been undertaken on the Chloride Powersafe product, to see if the technique could be used to predict product life. When the results of the tests were applied to the Arrhenius equation the subsequent plots gave inconsistant predictions and, in one case the prediction was wrong in that the value was less than actual service. Therefore, single mode failure criterea, essential for the application of the Arrhenius equation, may not be true for this type of product. In conclusion proposals are made that could improve the reproducability of the data, and observations are made that indentify the possibility that more than one reaction is involved in the life determining step of the product.
