Each cap can handle 2.7V long term, 2.85V short term. Balancer starts discharging overcharged caps through 1 ohm power resistor once they overshoot 2.8 - 2.85 V.

Self discharge current is expected to stabilize at relatively low value after 100 hours of being charged.

• Absorbtion current (initial)
• Leakage current (constant)

Replacing lead acid battery with supercapacitor

• UPS (replaced 12V 7Ah)
  • 8W LED was running for over 5 minutes
  • 100W incadescent bulb was running for 30 seconds
• Piaggio scooter (replaced 12V 10Ah AGM)
  • Charges to 14.4V (in ~1 minute)
  • After sitting for 9 hours voltage drops to 12.2V (cranks up)
  • After sitting for 15 hours voltage drops to 11.2V (cranks up)
  • At 8V (cannot crank up)
