This review is from: Maxell CR2032 lithium ion batteries (pack of 5 ) (Electronics)

Got my 5-pack of individually sealed Maxell batteries from the vendor, Best Price Mirror for a reasonable price shipped. There is NO use by date on the package/packages and they were made in Japan. See some of my other reviews on batteries if you want to compare. These batteries are a bit too stale for my interest, but for the price they will give you lukewarm results. I tested the open voltage on them and they vary but average 3.07 V at 23 C. That qualifies as a new battery, but it is far from fresh as a new shipment of (Duracell's, Energizer's, etc.) from the local department store. Great batteries start out with open voltages around 3.35 V. The significance of the 3.07 V value in this case is that either they are two or three years old, or were stored less time but in a warm place (or they meet a lower spec, or are off spec).

Overall, these Maxell CR 2032's don't measure up to the Sony's (5-pack individual perforated blisters, made in Indonesia) which I ordered at the same time on Amazon and arrived the same day and I measured alongside them - the Sony's were purchased from National Brand Dist and had an open voltage of 3.20 V and were all uniform, which is great. The lower voltage would not indicate to more than 40% loss and still exceeds the manufacturers spec sheet claim (which is purposely a conservative claim). I also tested these batteries side by side with new Energizers and new Duracell's, which were both over 3.3 V. The Maxell's were packaged similarly as the Sony's in 5 attached on a perforated card with individual sealed blisters. However, their open voltage was only 3.07 V on the average. Unfortunately for the Maxell's, there was variation among the Maxell voltages among those batteries - this is not as good and was not the case with the Sony's. The Sony's beat them hands down. My dead batteries all have open voltages between 2.75 V and 2.80 V in my kitchen scale application. While the discharge is not "linear" it still gives a good idea of what you are getting and I feel comfortable with my conclusions.

I don't recommend these Maxell CR 2032's 5-pack, individually packaged from Best Price Mirror if my shipment was representative of all the sales. I've reviewed other cheapies and have not recommended any of them ... except the Sony's. I hope yours works out as well: Good luck!

EDIT May 16, 2011: I edited out that the Sony's were cheaper since this is variable. I would like to add that in my application, which has a pretty uniform use, the kitchen food scale, a pair of 'new' Maxells ordered (of the five-pack) and reviewed here lasted 19 days. This compares to new Duracells from the supermarket (with starting open voltages over 3.35V) which lasted 53 days for the same scale immediately before this purchase. That is ony 35% of the energy I got from the Duracells. To allow that they may have been used a bit more, in the best case they had up to 50% the juice of new Duracells for me, probably less in the practical use (vs. my estimate on voltages of 60%). Anyway it is basically in the same ballpark. One further comment: If you are going to buy these and your device takes pairs of batteries, buying 5 will leave you with an extra as you burn through them. So you might have to get 10 (two five packs) in that case. I would not recommend pairing these Maxell batteries in light of the results, since batteries working together should drain uniformly to get the maximum economy out of your purchase. Frankly, these are different enough in initial charge as purchased that I'm going to check the remaining three individually and pair the closest two. That is another reson these batteries were a pain. Good luck with your set.

[second EDIT update June 4, 2011: a second set of Maxell's once again lasted 19 days in the same kitchen scale application].

Received these batteries to replace the ones in the bathroom scale. After several searches I ordered these as the price could not be beat. Waited patiently for them to come arrive from somewhere overseas. When they did arrive they looked as pictured; a sealed blister pack of 5 Maxell batteries.
Sadly not a single one of the batteries worked - they are stamped with "09" on every single battery (not sure if that is their expiration year but regardless they are duds.
Too bad as it seems like these got a large number of postive reviews.

Just a warning that at least one of these sellers [bestpricemedia.] is only shipping one battery, not 5, but most seem to be shipping 5, make sure before you order.
