Some Problems Associated with the Charging of Dry Batteries

The effects of the periodic application of a reverse emf to dry batteries, with the object of increasing their service life, are discussed and the optimum conditions to minimize the possibility of damage to both fiat and round cells are laid down. The application of this process in ac battery portable radio receivers is examined and it is shown that the extent to which battery service life is likely to be increased is dependent on the conditions of use of the receiver in question.
