Research, research,…..so much information out there about hearing aid batteries. But are any brands better then others? I think the real answer lies in the diaper analogy. Some people swear certain brands are better then others. Same for batteries. The most important information needed when buying batteries for a hearing aid is how much do they cost and how east are they to get when you need to buy them. Some people just order them off the internet and have them delivered. This can be a very smart option because you can be sure to always have them available. No batteries= no hearing aid.
