These are great power storage devices but you should buy more than you need so you can replace any that do not charge properly. Out of a dozen purchased I had 2 that are leaky and charge very slowly compared to the rest and after charging them they self discharge because they are leaky. The other 10 capacitors hold the charge well. I purchased 2 PC boards with balanced charging components on them to put 6 capacitors in series to make a 16.2 volt capacitor banks. One bank charges quickly and holds the charge a long time but the one with 2 leaky caps discharges the 2 caps leaving only the other 4 holding a charge hence rendering the cap bank unusable for high current engine starting but will work for car audio power amplifier high current supply during power amplifier demands.

I have tested a few of them, charged up to 2.6V on the next day they will have around 2.5V, so it is quite a small self-discharge, when they are at around 2.2V they can keep the charge around that value for 2-3 days before dropping to 1.9. Good for powering tiny electronic components even for several hours.

I ordered totally 29 capacitors (500F, 2.7V) . Three of them were wrong capacitors (22000µF, 63V). Most of them had capacitance around 300F, much less than in description. Best one had 504F and worst one 198F. All of them had huge leak current. I charged them to 2.5V and after 24h they had generally 1.1-1.2V. Best one had 1.4V and worst 0.3V. Thus, huge leak current and big variation in capacitance I consider quality of these very poor. These were useless for project in which I planned to use them.

Caps leak charge and don’t keep it more than a few days.
