| Advantage | Benefit for Your Application |
|---|---|
| ✅ 3000F in One Ø60×138mm Cell | 3.04Wh of instantly available energy in a single large-format can - fewer cells per module, simpler series strings for 48V-800V new-energy and backup systems. |
| ✅ 130A Continuous / 2400A Pulse | 0.20mΩ ESR-DC supports instantaneous high-current charge and discharge - ride-through for wind/PV generation dips, kurzing-time buffering and engine/motor starting. |
| ✅ -40~+65°C Wide Temperature | Maintains normal operation where lithium batteries fade - Arctic, high-altitude and unheated outdoor cabinets; HT series option extends to +85°C. |
| ✅ >500,000 Charge-Discharge Cycles | With 20 cycles per day that is 60+ years of service - far longer than traditional batteries, eliminating periodic replacement in remote power stations and embedded equipment. |
| ✅ Stable Electrical Performance | Low 4.5mA leakage (72h) holds charge for long standby - ideal for backup power, data protection and long-term low-current discharge scenarios. |
| ✅ Simple Charging, No Memory Effect | Fast charging with simple circuit requirements - no complex BMS for single-cell use, and UN38.3 / MSDS / CE keep worldwide shipping smooth. |

Q1. What is the 3000F hybrid super capacitor used for?
A: It is a 3000F / 2.7V large-format cylindrical cell for new energy power generation, backup power, energy storage and high-current operation - typical uses include wind/PV ride-through, smart-grid buffering, engine/motor starting, UPS data protection and pulse-load electronics.
Q2. The cell is 2.7V - how do I reach higher voltages?
A: 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 +65°C for operation (top of cell) and -40°C to +70°C for 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 130A (2400A for 1-second pulses at 25°C) 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. MOQ is 20 pcs, samples negotiable.
