Abstract

A study of charging capabilities of Nickel Metal-Hydride AA batteries was conducted using two different circuit designs: a half-wave rectifying circuit and a full-wave rectifying one. Even though the expected decrease in charging time was not achieved, an interesting discovery arose in that the batteries charged in the half-wave rectifier had a lower lifespan than the batteries of lower energy ratings that were charged using a full-wave rectifier.
