Rayovac Size 10 Hearing Aid Batteries, 24-Pack 10-24

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.

I have used Rayovac hearing aid batteries for several years and have not found any other brand that lasts any longer as a rule. However when I received some Rayovac packages at my local drug store last fall that had a short service span, I sought a source for batteries less apt to have been aging in the retail inventory and delivery chain. I was pleased to find that these could be purchased directly from the manufacturer. I was also pleased to see them marked: "BEST IF USED BY 03/18" which is a later date than any I have purchased in a store.
