Among electronic components, supercapacitors are favored by more and more people due to their advantages such as large capacitance, high power density, fast charging speed, long service life, and environmental protection, and are widely used in new energy applications and electronic products.

Supercapacitors should also be maintained during use so that they can play their role better and last longer.

Precautions for maintenance of super capacitors:

1.Pay attention to the voltage: supercapacitors have relatively strict voltage requirements. If the rated voltage of the supercapacitor is exceeded during use, the electrolyte in the supercapacitor will decompose, the supercapacitor will heat up, and the capacitance will decrease, which will affect the life time of the supercapacitor. Therefore, pay attention to the voltage of the supercapacitor during use, and adjust it in time if the voltage is found to be inappropriate.

2.Storage environment: The correct storage environment is the key point to protect the performance and service life of supercapacitors. When using supercapacitors, store them in a suitable environment. The temperature should be kept between -40~ 50°C, and the humidity should be kept below 60%. The storage environment should avoid toxic and harmful or corrosive gas and liquid environments, otherwise the supercapacitor shell will be corroded and lead to open circuit.

3.Pay attention to the polarity: In addition to the voltage standard, the supercapacitor has a fixed polarity. Before using it, you must confirm the polarity of the supercapacitor to avoid affecting the performance of the supercapacitor. Do not forcibly tilt or twist the capacitor after connecting to avoid loose leads of the supercapacitor, resulting in performance degradation.

Regular cleaning: Check whether there is dust or dirt on the supercapacitor shell, mounting bracket and other parts. If there is, clean and remove the dirt in time to prevent short circuit caused by static electricity.
