For minimum backup times of standard and vertical miniaturized series see Figs 9 and 10 (charging time 24 hours). MGA695 Vishay BCcomponents Figure 11 shows the backup time when a 196 DLC capacitor is discharged by a constant resistance (charging time 24 hours). The horizontal axis shows the initial value of discharge current if 5 V is connected to the capacitor via a fixed series resistor.
