How long do these usually last? Like a single battery?

I've been using Duracell batteries for the last 9 months, since Feb. 8, 2017. I've always kept a record of my hearing aid battery usage since I started using hearing aids in July 2005. The battery in my right hearing aid lasts 4.5 to 5 days & the battery in my left hearing aid lasts 5 to 6 days. I can't see much of a difference in time from the batteries I've used before but the purchase price on this Duracell order was the best I could find lately.

Are the duracell activair hearing aid batteries mercury free?

Since info says zinc air I assume they are mercury free. Better be.

I'm going to make an assumption here. I am guessing that that customer wants to know where they are made, not just the brand name. These Duracell batteries most likely were made by Duracell. According to the packaging, they were made in Germany. They work very well and, so far, have last longer than other brands. Hope this answers your question!

What is the difference between a #10, 4v. And a #10, 4.5v can they be used interchangeably? Will it damage my aids?

You mean 1.4 vs 1.45 volts? I guess standard #10 is 1.45V. 1.4V will not damage Aid, but may perform below peak.
