Claim Text:
1. A circuit, comprising: one or more electrochemical cells; a charge/discharge circuit configured to respectively generate charge pulses and discharge pulses to the one or more electrochemical cells, wherein the charge pulses and discharge pulses include a first transition rate; and a transition modifying circuit operably coupled between the charge/discharge circuit and a terminal of the one or more electrochemical cells, the transition modifying circuit comprising at least one circuit element configured to receive and modify the charge pulses and discharge pulses to exhibit an adjusted transition rate on the terminal that is slower than the first transition rate and sufficient to reduce degradation of one or more charge capacity characteristics of the one or more electrochemical cells, wherein the first transition rate and the adjusted transition rate include rise and fall times for their respective pulses.
