Are the size 10 batteries 1.4V? What is the expiration date on the package I would be buying? Thanks!

Guy: I am sorry, but I am unable to answer your question because I had already discarded the packaging that might have provided this information. I do really like these Rayovac batteries for my hearing aids. By far they seem to last the longest for me and my use and the convenience of the quantity and price. I will be ordering again. Have a great week.

The size 312 batteries I bought in June 2013 have an expiration date of April 2017. This vendor seems to turn its inventory quite rapidly, so I'd guess that batteries bought now would be dated a couple of months later. As to voltage - the Rayovac website has detailed data sheets on each of it's batteries.

the "10" as first digits means manufactured in 2010. Realistic life expectancy of battery is 8.5 years. You should buy only ones with with "13" or "14" and not a "10"

Hi...i'm really unsure as to the voltage....it is not specified on the battery....only 1000mah.....so far they have worked fine in little devices

They were 2015, not sure about the voltage, fit size 10 hearing aid which is a miniature size. I send them overseas otherwise I could check the box for you.

my batteries had a " best by" date on the side of each of the batteries. The date was 4+ years from the date of purchase. as I use 10 at a time to replace smoke alarm batteries this was an adequate shelf life for me.

I received mine in a small box. Each battery was upright, not terminals touching. The date says "1114A", which I guess means the batteries aren't expired. Nevertheless, that they are opened is worrisome.

I received the 7.4V batteries. They seem to work fine although i was concerned about the voltage increase.

The package indicates 1.45 V @ 180 mAh. So far I've experienced good results with these batteries, last 8 to ten days in my Starkey (NuEar ) aids. Hope this answers your question.

They are standard 9 volt. My experience is that a battery lasts 2-3 years. They aren't hard to change, but why be bothered? Buy the top rated battery.

April 2017....yes these are 1.45. They are the real deal. I checked w/ ray o vac They are all the same battery..they use different packaging/ for different markets. I ordered mine a couple months ago so the use by date will probably be even further out. This is my second order.

Hello John. To answer your question "what is the expiration date?"A box of 10 pkgs each with 6 batteries contained within was delivered the last week of December, 2012. Each pkg had an expiration date of 'Oct 2016' printed on the back of each pkg of six.This packaging allowed me a great value per battery and I am using the last package this week (7/08/13). So for six months I have paid roughly $0.42 cents per battery. And since I am a Prime user I did not pay shipping for this order. The size I ordered for my hearing aids is Size 10. I have tried many battery types and have my positive experience with the Rayovac size 10 has always been without issue. Good Luck. Hello John.

They are what they say, they last just as long as average battery but cheaper and with a long shelf life. Mine which I got last yr have a shelf life till 2015. I bought several.

my batteries indicate 11/2018. I find them most unsatisfactory and will not buy them again.

Mine just arrived on 16 June 2015 and the code on them are 1215 meaning they were made just a few months ago in the 12th week of this year 2015. Very fresh batteries. Good for 10 years.

Bought mine a few months ago. Use by date is March 2017. They are 1.45V (size 312). Have had very good experience with them.

NO! They are not the 1.5 Ah batteries and the listing did not state that they aren't the current 1.5s! My batteries are stamped 2011. Seller offered a call tag to pick them up and refund my purchase price, but then I'd be out the money for shipping and have no extra battery. No joy for me, buyer beware!

Sorry, there is no date on the batteries. I don't know what the guarantee period is. From experience over the past 10 years or so, the batteries remain useful for 4 or 5 years.
