Supercapacitors Storage Conditions
Store supercapacitors indoors at temperatures between 5 and 35°C. And keep relative humidity below 75%. Avoid sudden changes in temperature, as they can lead to condensation and product deterioration.
Also, avoid storage in the following kinds of environments.
- Environments in which capacitors could be directly exposed to water, saltwater, oil, or condensation, and environments filled with gaseous oils or salts.
- Environments filled with toxic gases such as hydrogen sulfide, sulfurous acid, chlorine, ammonia, bromine, or methyl bromide).
- Environments in which capacitors could be exposed to acidic or alkaline solvents.
- Environments in which capacitors could be exposed to direct sunlight, ozone, ultraviolet rays, or radiation.
- Environments in which capacitors could be exposed to severe vibrations or shocks.
If left for long periods of time, capacitors may experience changes in characteristics such as increased leakage current, decreased capacity, and increased internal resistance. When using products that have been left for periods of time longer than half a year, charge to their rated voltage using a current of 5 mA/F. Then apply the rated voltage for about 20 hours. After this, measure their characteristics to confirm that they meet the required characteristics.
