I put two sets of batteries through the wash in the handy dandy carrying case and they also endured a trip through the dryer. I wonder how they were affected.

I faced issues with another brand of batteries which caused strange issues with my hearing aids. However, I have switched to this brand and now only use this brand.
Ray O Vac hearing aid batteries last much longer than the ones suggested by the hearing aid company.
