Is it safe to operate an aluminum electrolytic cap at 10% reverse voltage? The cap is 1000uF at 35 volts and charges with about 1 mA of current at slow rates of 1 minute or less, and reaches 2 volts reverse v on each half cycle. Seems to work ok, but I'm wondering about the long term effects? I don't think there will be a heating problem with only 1mA of current. Will the capacitance change over time?
