Lead-Acid Battery: Float Behavior of the Lead-Acid Battery System

We discuss in this article the requirements for satisfactory float operation of lead-acid batteries and analyze behavior during float in terms of the kinetic parameters which characterize the electrochemical processes occurring in the overcharge region. We show how knowledge of these parameters may be used to estimate whether adequate battery maintenance can be expected under specified float conditions. The results emphasize the need for cell uniformity, and the treatment provides a basis for determining what variability is permissible.
