Q1. What is the 107-100F supercapacitor used for?
A: It is a 100F / 2.7V cylindrical supercapacitor cell for backup power, energy storage and high-current operation - typical uses include industrial EV and engine start assist, actuators, GPS/telematics burst transmission, smart meters, UPS data protection and renewable-energy buffering.
Q2. The cell is 2.7V - how do I reach higher voltages?
A: Like all EDLC-class cells, it is a single 2.7V element. Connect cells in series for higher voltage (e.g. 6 in series ≈ 16.2V) and use an active or passive balancing board so no cell exceeds the 2.85V surge limit; connect in parallel to add capacitance and current capability.
Q3. How long does it last?
A: Conventional supercapacitors of this family are rated for more than 500,000 charge-discharge cycles (hybrid LIC types: 250,000). At 20 cycles per day that is over 60 years of operation - cycle count, not calendar aging, dominates the service life.
Q4. What temperatures can it handle?
A: -40°C to +70°C for both operation and 0V storage, with normal performance at -40°C where lithium batteries cannot work. A high-temperature (HT) series rated to +85°C is available on request.
Q5. How do I charge it?
A: Charge with a simple current-limited DC source - no memory effect and no complex charge algorithm. Keep continuous current within the 20A rating (48A for 1-second pulses to half voltage) and never exceed 2.7V continuous / 2.85V surge per cell.
Q6. How is it shipped and certified?
A: Cells ship shorted with pearl-foam protection, certified to UN38.3 for worldwide air/sea transport; MSDS and CE documents are available on request.
