    There are many sellers for this item on Amazon. I’ve only purchased it once and therefore can only talk about one of those sellers, but maybe others will find this a helpful single data point.

    I purchased this item from Micro-Tools (fulfilled by Amazon). It was as described: 100 coin-cell batteries. They came in a plastic bag inside an Amazon box, packaged as ten strips of ten cells each. Each strip appears to be ready for individual sale (e.g., you could easily sell a strip of ten), in that it has a hole to hang the strip from at the top and a single UPC symbol at the bottom. The strips and batteries are both labeled with the “Suncom” brand. The strips have two dates dot-matrix printed on the back: P.D 01-2010 (probably production date) and E.D 01-2013 (probably expiration date). I bought these at the end of June, 2010, so it looks like I have about 2.5 years of shelf-life on them. I pulled one cell at tested it with a ZTS MTB-1 Pulse Load Tester, and it rang up at 100%. I put three of them in my daughter’s sound-generating book, and it worked as good as new.

    I am very satisfied with the batteries, the price, the packaging, and the delivery.

    First, note that this is a 357A rather than a 357. For most applications, this is unlikely to matter. Wiki Answers ([…]) has a description of the difference. Primarily, the voltage stays more constant for the 357 over the life of the battery.

    Based on prior reviews, I had two concerns: How many batteries would I receive and how many would be DOA.

    I received 100 batteries (10 cards each with 10 batteries.)

    As an initial test, I checked the voltage of a sampling of the batteries while they are still in the packaging. (There is a hole in the plastic blister and I forced the other voltmeter probe through the cardboard on the back.)

    I tested all batteries on the first card that I pulled. All ten were between 1.60V and 1.63V. Since I didn’t want to fight with 90 more measurements, I took a single measurement from each of the other cards, reasoning that all batteries on the same card should be from the same lot. In all cases, the voltage was at least 1.6V.

    Nominally, these batteries are 1.55V. As such, I’m expecting to get a reasonable life from these for my digital caliper, a non-demanding application. However, note that this is not a test under load. It is possible that a battery with defects would show a reasonable resting voltage, but a drop to an unusable voltage under load. In my case, it would take a very substantial reduction in lifetime or a very high defect rate for the value to be lower than for any other 357 option.
