Abstract A general calculation formula of the heat capacity for the HRN black holes is derived. The heat capacities for Q, Φ+ and r- fixed are obtained. Assuming that the charge-mass ratio of fluctuation modes does not exceed the extremal value, the minimum charge-mass ratio of the black holes for which the heat capacity is positive is determined.
