Energizer Sound Energy - Hearing Aid Batteries Size 312 (60 Pack) – Long Lasting Zinc Air Power - Easy Installation - Mercury & Cadmium Free - Made in UK - 4 Year Shelf Life [Amazon Exclusive]

I was initially cautious about buying these hearing aid batteries online, but I’m so glad I gave them a try. They’ve completely exceeded my expectations. These batteries clearly last longer than the ones I used to receive from the NHS, which have become increasingly difficult to get due to the hassle of requesting them with a stamped envelope, etc.With these, I’m getting over 10 days of consistent performance, which is significantly better than the 5 days I was getting from Varta batteries purchased at Boots. The difference is noticeable, and it's made managing my hearing aids much less stressful.Now that I’ve found a reliable, longer-lasting option that’s easy to order, I’ll be buying these with confidence moving forward. Great value for money and highly recommended!

Normal batteries. Last about 6 days.

Excellent value for money, and they last for a decent length of time. A box of these lasts me several months, though I admit I've not kept an exact record for that purpose. I suspect it might be longer. Of course it very much depends on how long you wear your hearing aids for.My main caveat for this review is that I've tried no other batteries. But better the devil you know.

Great value

Good quality product, only problem is only lasts 3 days but have found that with other hearing aid batteries. Easy to useArrived on time.

Good batteries seem to last longer than one of the leading brands.
