Private-label batteries from the well-known Clinic typically lasted three days, but with changes in suppliers, battery life diminished. Some lasted only 15 minutes, and none more than a day. After several boxes of batteries (10 cards per box) with no improvement, I tried Ray-O-Vac direct order. The product has been excellent, with full five-day battery life. Higher cost per battery, but much lower actual use cost. The Clinic could offer batteries for free, but I'll stay with Ray-O-Vac.
This product is dependable and lives up to its hype.

I have been using Ray o vac batteries for as long as I can remember. They are easy to install into my hearing aids, and they perform perfectly. They also are the longest lasting batteries that you can buy, and on-line ordering is fast and simple. You can count on me as a future customer for a long time.
The new "Longest Lasting" #10 Hearing Aid Batteries are significantly more reliable than the previous batteries. The benefit to the user of the "Longest Lasting" batteries is that they are consistent. They work well; there are no bad batteries in the batch; and these batteries retain their potency for the entirety of their life. The new "Longest Lasting batteries, in my experience, don't actually last longer than the old ones (usually one week); but these new batteries can be counted on to work well and do their job well. I am pleased to use them.
This battery really last longer than other brands. The one thing that I do not like in the packet is that, there is one or two batteries that does not work or defective. It did not happened once but more than a couple of times. Hopefully this could be remedied.
