I tested capacitance at different voltages, results below: 12.01 - 37.7uF 19.00 - 28.2uF 28.69 - 13.7uF 29.80 - 9.14uF I used adjustible voltage source and switch, capcitor was connected in series with 1kOhm resistor, voltage was mesured at capacitor by oscilloscope. Capacitors gives match higher capacitance drop then should, for exemple at 12V they must have 88uF. So seller described it wrong, but at low voltage and for that price - not bad.
super fast delivery - thank you :)
