50 Powertron 3v Battery CR1220 CR-1220 Lithium Batteries DL1220

Pros: They work and they're cheap. Used them to replace dead batteries in a keychain LED flashlight. I actually tested them with a multimeter and they do register as 3V.Cons: I received "Wama" brand batteries in similar orange and white packaging, not Powertron. It's a nitpick, and I've never even heard of the "Powertron" brand, but minus one star for a false product title. Label it as "generic" and be done with it...

The brand name I received was Eunicell, which is fine with me. 10 packs of 5 batteries each. I paid a little less than 16 cents per battery. From a value vantage that is extraordinary. If I have any negative issues, then I will edit this review. But as it now stands, fine product at a fantastic price. I would say that I will "buy again," but I think I may have a 50-year supply with this order.

Saved tons of money on this purchase. The batteries last as long as any other big names I've bought before. I put these in Christmas light necklaces and they go for about 6-8 hours, which with these necklaces is the same for name brands. They are name brands before they're repackaged.

These batteries have no life in them at all. They die in less than a day whereas previous orders with other suppliers would have batteries that lasted months. We are having to replace the batteries constantly in our gear and it's such a pain that we are tossing this entire order out and will just continue to order with our old supplier.

These were all bunk! Didn't work. Unfortunately I didn't discover this until after the 30 day return window. And no, I didn't wait that long, they weren't expired or anything. Just a couple months after buying. Waste of money!

Great price. They showed up quickly and they work.

Batteries worked great! Wish tracking the shipping could have been more detailed...

Excellent. As expected.
