Charge a nickel-cadmium cell reliably and inexpensively
Charge a nickel-cadmium cell reliably and inexpensively
12.16.2017 · Circuits
Rechargeable NiCd cells are widely used in consumer devices because of their high energy density, long life, and small self-discharge rate. As a part of one project, I needed to design a reliable and inexpensive charger for a battery pack containing two NiCd AA-size 1200-mAh cells. In the process of the charger design, I needed to solve two main problems...
