A new equation for the limiting capacity of the lead/acid cell
Abstract
As an alternative to the empirical Peukert equation, whose validity is restricted to intermediate discharge rates, a new equation for the limiting capacity of the lead/acid cell is proposed, formally derived from an approximate closed form solution of a two finite compartment diffusion problem. The four parameters of the equation are evaluated through a non-linear least-squares method. The resulting capacity curve fits the typically undulating experimental data closely throughout their range.
