The analysis of the empirical relationships describing the discharge of alkaline accumulators

It is shown that at small discharging currents for any nickel-cadmium (NC) accumulator the empirical relationship by Khaskina- Danilenko is true and at large discharging currents the relationship by Shepherd is correct. These two relationships don't contradict each other but supplement each other, as they are true for any NC accumulator, each in its interval of discharging currents.
