The effect of fast and three-step charge mode on the capacity and cycle life of lead±acid battery negative plates was investigated using a model mini electrode (ME). It has been found that the charge algorithm exerts a strong effect on the charge acceptance of the negative electrode. In the two-step charging mode I1, j2 with increase of the current at the ®rst step of charge, the capacity of the negative electrode decreases and the cycle life shortens. This phenomenon is reversible as it is probably due to the incomplete reduction of PbSO4 to Pb. The phenomenon is explained...
