Button batteries discharge characteristics

The battery is constructed in the button-type configuration and typical discharge characteristics are shown in Fig. 9.16. The rated capacity of this particular cell was 36 mAh and its reported energy density values were 44 Wh/kg and 150 Wh/dm3. 

These batteries are built in cyclindrical, button or prismatic configurations. The capacities of portable cells vary from 35 to 2,400 mAh. Their discharge characteristics are similar to those of Ni-Cd batteries. The discharge voltage is around 1.2 V. 

The effects of discharge level and signal frequency on the internal impedance characteristics of the DA13 and DA675 button batteries are presented in Fig. 13.11.
