The charge rate is equal to one time constant if you charge one farad at one amp for one second. A time constant is 63 percent. I put my 2600F ultracap on a 2.5V, 1 amp power supply, and it takes more than an hour to charge fully. Remember that it slows down at the end., If you compare a regular 1000 uF electrolytic to a glass of water, these ultracaps are like a swimming pool!! They're incredible! And a Joule Thief will run brightly for days on one charged to 2.5V..
@donahuerules , Not sure what you're asking. Discharge rate and charge rate change with amp draw and charge amperage. But the capacitor is rated at 3000 Farad.
Nice job! You light should be very bright for a long time with that sized boost cap. I am jealous and want one, ha ha. I am guessing it did not take that long to charge up either, which is another reason I like these caps.
Very well done. I am looking forward to seeing more of your experiments here.

how long does the dicharge rate last and how long does it take to charge up
