The dry aid companies recently put out a letter recommending that you should put hearing aids with the batteries in the dry aid kit overnight. The dry aid kit removes moisture from the battery. If you are in a high humidity climate it may help, but if you live in Arizona in the summer where it is dry, the kit will shorten the life of the battery. Results can vary, so my recommendation is to judge it on a case by case basis. There is not one good answer.
