Genuine Maxwell - BCAP3000 P270 K04 - Supercapacitors / Ultracapacitors 2.7V 3000 Farad Threaded Terminal

Maxwell Technologies, Inc. was an American company that specialized in the design and manufacture of energy storage and power delivery solutions. In 2019, Maxwell Technologies was acquired by Tesla, Energy Storage and Power Delivery Solutions who sold it to UCAP Power (San Diego-based startup) in July 2021. Ultracapacitors are the technology of choice for high energy/power applications because of their long operating lifetime, low maintenance requirements, and superior cold weather performance when compared to batteries.

Since Ultrcapacitor /Supercapacitors have a much higher rapid charge and discharge capability than batteries they are generally used in parallel to maintain system voltage during high current conditions which greatly extends the life of batteries.

Ultracapacitor are discharged after testing using high wattage resistors. Afterwards a shorting wire is attached across the terminals for storage and shipping. Ultracapacitors have an unlimited shelf life when stored in a discharged state. Before installation remove the shorting wire. Due to high current capability of Ultracapacitors they should be discharged using a high wattage resistor or alternately using a low voltage/high wattage bulb.

Cautions: Do Not Reverse Polarity, Do Not Open, Do Not Put into Fire, Improper use May Result in Personal Injury and/or Equipment Damage.
