INITIAL CHARGE. An initial charge is necessary if the capacitor voltage is lower than 1.29 V per cell. For a system with n = 3 cells, the limit to start an initial charge cycle is 3 x 1.29 V = 3.87 V. The nominal voltage of this system would be 3 x 1.4 V = 4.2 V. This initial charge voltage of 1.29 V per cell is temperature-independent.
