I am extremely pleased with the batteries that I purchased. They are the exact original equipment manufacturer as the batteries that came with my glucometer. I haven't read it anywhere but more and more we are seeing different devices that operate by battery becoming finicky about the batteries matching I have had problems using two different fresh batteries lithium ion coin type to be specific in my glucometer it will not take them. Somehow the glucometer detects that the batteries are made by different manufacturers or fresh batteries that are the same brand however the expiration date is different. This isn't the first time I've encountered a device that wouldn't take the different brand batteries I tried to use or different expiration date by the same manufacturer. These batteries are extremely fresh I popped him in my glucometer and went through the time and date set up very quickly and thus far I'm very satisfied with the Panasonic lithium-ion batteries.Read full review

These seem to be losing voltage without being used. I got six and I used two of them ritght away and they worked well, but now the ones I saved for future need have lost some of their voltage in storage. New they were 3v. But now after a year unused they are down to 2.55 v. I would suggest buying them as needed, and not in anticipation of need. In general I have had good results with these and other types of Panasonic batteries. No leakage or corrosion that I have observed.

So much less expensive than I can find locally. Many years ago I was scuba diving and found a dive light someone had lost. It had been down there long enough to be covered with barnacles, but still worked. Inside were Panasonic D cell batteries. That left an impression on me. I am still a fan of Panasonic batteries and have never been disappointed in them. My only problem is putting them somewhere I can find these "spares" in the future. I think I have that figured out this time. These came in nice individual sealed plastic see through envelopes, so it's not a matter of throwing loose unprotected batteries somewhere they short out or lose their charge. And these are supposed to be good for nearly 10 years. With inflation, I'll probably be money ahead buying now.

I use my LED hat(s) frequently and other co-workers and friends are envious of the hat's features and benefits. I get well more than a few months of occasional run time from the set of batteries to my satisfaction.
