The Rayovac hearing aid battery has a pull tab that, next to the Duracell's, is the easiest to grasp. I judge these to be a good comprise between the number of the days the batteries last and the convenience of pull tab that is moderately easy to grasp.
It seems counter-intuitive that many brands of hearing aid batteries have tabs that may prove problematic for the elderly to grasp. The elderly, being the very demographic most likely to use hearing aids, often are the ones who may have the most physical or mental challenges associated with grasping small battery tabs. The Duracell folks have got the pull tab design that is the most convenient. However, I found that they last a full two days shorter than the batteries made by Rayovac.
never been disappointed in the service and quality. best deal around!! this should be advertise more to the public - I found out about this through my co-worker whose husband works for rayovac
