    the value on the cap is as follows all readings were done out of the circuit
    2200uf 16v esr reading 1929uf 0.03 esr

    Hello,

    With what instrument did you measure the values?

    Electrolitic capacitors can have tolerances upto 20 %.
    This means the 2200 μF can measure any value between 1760 and 2640 μF.

    Greetings,
    Bertus

    1929 uF is within the range of acceptable for most standard caps.

    Depending on your circuit, it may or may not do.

    If you have a circuit that requires very accurate capacitance, it may not cut it.

    Is there any visual signs of damage? Odd stains, ruptures, or dents?

    Hi Do you have a chart of resistance readings vs capacitance values. My DICK SMITH ESR shows 1000uf at .09 ohms and 4700 uf at 0.20 ohms , it does not vave a value for 2200uf, but by extrapolation I would say a .03 ohms reading is good.
