AG10 Button Cell Batteries (10-Pack) - LR54 Alkaline Batteries for Watches, Calculators, Toys & Small Electronics

I posted a negative feedback about these batteries. I MADE A MISTAKE (actually 2 mistakes). I said all 10 batteries were dead.The batteries are fine! Mistake #1: I ASSUMED my calculator had quit because the battery was dead. When I installed the new battery and the calculator didn't work, I ASSUMED the battery was bad. I tried a second battery. The calculator still didn't work.I went and got my battery tester. I tested all 10 batteries. Mistake #2: I was looking at the wrong scale on the battery tester.I didn't notice there were TWO SCALES on the battery tester. I thought they were all in the RED ZONE (bad battery). How evera little bitty scale for button batteries, under the main scale, indicated they were all fine. I discovered this after I checked the batteries with a multimeter and they all read 1.5 volts. The Seller, National Deals, called me within hours after I posted the negative feedback and offered to send me new batteries right away. I need to apologize to them for posting a negative feedback. The batteries are fine, they are brand name (Maxell) and were made 3/14.The calculator is toast!! MY BAD!! I can't use my battery tester correctly!! MY BAD!!National Deals, please forgive me. Thank you for great customer service and a good product at a low priceTom N.
