good

They are batteries what can you say about these?

Got these specialty batteries for my overhead fans. They work

I’m giving these 4 stars solely based on cost & quantity. I have yet to use them except to see if they work. They do. I tried all 4 and they powered my LED light for about 20 seconds before I took them out. My only concern is the Chinese writing on the batteries. I’ve never seen real Duracell batteries w this writing sold in the US. They could easily be knockoffs but I can’t be sure. I don’t see any expiration dates on the batteries themselves which is a red flag as the majority of battery companies have the expiration (best by) on them (or the packaging). That being said, if they work well I won’t be too upset. They could be batteries made to be marketed in China and are now being sold in the US. I really don’t know but I will update w any information that the buyer may want to know before purchasing.

Lasts longer!

Good product at a fair price. Quick delivery.

I bought these because the battery in my garage door opener died. I thought the opener took a AAA or AA battery but needed this specialty battery. My experience told me you can run all over town looking for specialty batteries and come up short so I looked on Amazon knowing they would have it. This particular one had the Get it Today shipping feature which I needed. I made the purchase at 10:00 PM and my order was delivered at noontime. I am happy to have gotten them so quick. Thank you Amazon. I love being a Prime member!!

came with insufficient postage...had to pay $1.23 ( so postage was falsely advertised as FREE)
