Self-discharge is the one of the most significant disadvantages of nickel–cadmium batteries. At a nominal storage temperature of 20 °C, the rate of self-discharge, or the capacity loss is 10% in the first 24 h and around 20% per month for the first month. The rate decreases for storage beyond 1 month, but it is still significant for most
