    Self-discharge rate of Super capacitors:

    A) 10-20% of their charge per day

    B) 1 - 2% of their charge per day

    C) 0% of their charge per day

    D) 100% of their charge per day

    Correct Answer: A

    Solution :

    Option [a] is correct. Explanation: The disadvantage is that super capacitors aren't well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithiumion batteries; they can lose as much as 10-20% of their charge per day due to self-discharge.
