To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I agree with several other buyers about these batteries. As I am just now trying some of them to see how long they last I am being generous and giving 2 stars. The problem is that the batteries do not come in original packaging...not even close! Mine came loose in a padded envelope. It appeared they had been put in a plain small collapsible cardboard box, but it had well...collapsed...and the batteries were all loose in the envelope. I am not sending them back, not worth the hassle, and I am going to give them a shot. IF they turn out to last, I will update and change my star rating. IF they don't, I will also update with that outcome, too. I will say that all of the batteries have the same expiration date, MAR 2019.
***Update:3/6/2014 I am adding a star to my review as I have used a few of the batteries and so far they are all still working.
I ran life tests on AA and AAA Duracells, and the AAs are 2.5 times longer lived. I modified my forehead LED light to use AAs and there's quite a difference. However, our blood pressure cuff uses AAAs and so does our LED flashlights, so we're stuck. The ones rec'd yesterday from Amazon have a full 10 years from 2020.
these batteries were packed with great care, taped up and protected in a box, so I'm not sure why the quality of them seems lesser than normal. they are less strong than duracell coppertops I usually buy. I don't know if it's because they were shipped in cold weather, or if they're old, or maybe not authentic. I bought these because we use them for a high energy draining device and I've read that duracell coppertops are best for that use. but I have to replace these rapidly. I give them 3 stars because it's a good price for a generally good battery, if you're using them for most practical purposes like remotes or clocks, etcetera. would be 5 stars if you could use them for high drain devices.
Like other purchasers, I bought these batteries from Amazon (not from a 3rd party company) and did NOT receive the batteries with the "10-year guarantee in storage" that I purchased. Instead, I received batteries that are only "guaranteed fresh 7 years" (that's exactly what it says on the packaging). Even worse, the batteries have "Mar 2018" stamped on them, which means these batteries are already 2 years old and only have 5 years of "guaranteed" life left on them -- half of what I paid for since I expected to receive fresh batteries with a 10-year life. It isn't worth my time or effort to return these, especially since I might receive old batteries in exchange, so I guess I'm stuck with them. I buy lots of stuff from Amazon, but I won't be buying batteries from Amazon again. Even if it's more expensive at a local store, at least I can see the date on the batteries and know that I'm getting what I'm paying for.
Received the item in original Duracell packaging however I ordered the 20 count pack, but there were only 18 included. It was sealed completely and did not have any indications of being tampered with, so it might be an issue during packaging itself. Tested the batteries and all were working, also no leakage or corrosion. Given the price, this is definitely good value, but should have correct battery count for each pack.
I haven't used these yet, so have to assume they are ok. However, when I ordered a 20-count battery item, I assumed that the batteries would be packaged in a "brick" or other multi-package like you normally see in stores, and that the package itself would be contained within a box with other packing materials of some kind for security and damage prevention. Instead, I got 5 packets of 4 batteries each, all of which arrived loose in a small cardboard box without any other padding or materials to prevent them from rattling around against each other in transit.. It was strange.
