    This review is from: Rayovac Proline Size 312 Hearing Aid Batteries, 48 Pack (Health and Beauty)

    I have been using hearing aids for 4 months now. These batteries were the ones I ordered after the free Energizer batteries ran out. I get 5 to 7 days depending on how many hours a day I wear the hearing aids which run from 6 to 10 hours a day. I cannot tell very well when to change them though, usually after I say “Huh” to 3 people in a row which is probably too long. The effectiveness does not drop off quickly but very gradually. I wish it was easier to tell when they weren’t working. When I was not wearing the hearing aids I would open the battery holder so the batteries no longer were in contact to extend their use.

    Things I liked:
    – The packaging is very nice. I remove the plastic dispenser wheel from the cardboard backing and it fits nicely in the hearing aids case. I always have up to 8 extra batteries when needed. I put the used batteries back in the dispenser when expired. It is easy to tell the difference between used and new. I will be looking for a place to recycle them when I get the next package.
    – Batteries seem consistent in how long they last, they also appear quality made.
    – Great price and free shipping, but that is Amazon not the batteries.

    Things I disliked:
    – They don’t taste very good. Oh wait that is for a different review! Yeah I am getting older.

    Nothing I dislike so call it a definite recommendation from me.

    Edit: now 3 months later.
    During a visit to my audiologist I was informed that my Hearing Aid will beep when it is time for a battery change. So I let it run to that point and in fact when it did beep I thought it was someone else’s cell phone. I have since found that using this method these batteries last between 10 and 14 days for me. I was fairly shocked how much longer they did last compared to my preconceived notion as to how often to replace them. I have not noticed any degradation to any functions to the hearing aids at all over that period of time.

    Now I am wondering if anyone knows where these can be sent to be recycled? It seems a shame to throw out something that appears that it can be so easily reused.

    All my previous hearing aid batteries have lasted only about 8 hours. These last a full week! Truly amazing.
