Eunicell CR2032 5004LC 3V Lithium Coin Cell Batteries (10-Pack) - Long-Lasting Power for Watches, Key Fobs, Calculators & Medical Devices

Worked as needed in 35 year old calculator.These batteries work extremely well, especially considering that the price is one tenth of what you would spend at a retail store for the same quantity. I'm always finding a need for these batteries.What's even more impressive than these batteries is the huge packaging they arrived in, warning about the volatile and eruptive possibilities associated with lithium batteries. I had to contact my local law enforcement agency's combustible ordinance team just to determine if it was safe to open the package. Added a bit of excitement to my day!I was confounded as to which CR2032 batteries to get after reading negative rviews so I went with what I figured many users outside of the U.S. most likely would purchase.J oedered 5 and got 10..HMMMM I became a bit perturbed ...but no worries..THEY WORKED!!!Batteries are batteries the don't last forever. This is why this are pretty good and for the price they are even betterJust what I needed. Worked well in my truck remote.Very happy with these. They work in both my body scale and my food scale and in one of my son's toys. Seems to be a common size. They seem to last fine.I purchased these as replacements for the batteries in sets of LED fairy lights used in dioramas we display at shows. Most other brands last an entire day or more; these lasted 3-4 hours under the same conditions.These are new batteries but when I put them in my thermometer it shows low battery.The price is right. The don't last as long as the name brands, but at this price I can handle it.Worked like a charm. Bought in bulk for some projects for kids at the local library.
