should i buy Duracell Coppertop Batteries reviews

I'm pretty used to buying batteries online and finding they had been made long before I ordered them (had some CR123 with experations the next month from another vendor). In at least my case, my batteries from this vendor show a production date of 3/30/10...and I ordered them on April 18th. You can't get any younger batteries (exp is Mar2016). I'll be checking this distrbutor out for the rest of my battery needs. I got these about three weeks ago, and still haven't used them up yet. So many batteries. Awesome. So far, they've lasted about four times as long in my Canon digital point-and-shoot than my Energizer rechargeables. And they're on track to outperform the regular Energizers in my Xbox controllers. I think I'm a coppertop convert. The price is pretty good, too--probably not the absolute cheapest, but these are real Duracells (not knockoffs) that are far from their expiration date.

The 4 batteries arrived in 4 small ziplocs rather than in sealed Duracell packaging as shown in the picture. I have no idea if they are new or used.

These batteries were purchased on Amazon along with a new Coleman LED lantern, as a gift for my mom. They were put into the lantern, they did work, but the next morning there was battery acid all around the base and in the lantern. I do not know what would be the cause of this, nor the expiration on the batteries, they were sent to my mom in a different state than where I live. 1 box with 2 boxes inside clearly the original Duracell boxes. Have not used batteries but all looks just like from the store. Unfortunately no expiration date. There was a time when I thought Duracell batteries were among the best. That is no longer the case. I just pulled another AAA dated Mar 2015 that was leaking out of a devise. The battery case had ruptured. I have seen a number of these ruptured cases over the many years we purchased Duracell (we still have a few left for use only in inexpensive devises) I'm not sure when the problem started and I noticed some time ago that Proctor and Gamble now owns Duracell. We have not patronized Proctor and Gamble for over twenty five years so Duracell is no longer our battery for two reasons.

If you are looking for a good AAA, AA, C, or D battery, may I suggest Kirkland or Panasonic. I do not know who manufactures either.

A note on Energizer and possibly other batteries. About twelve years ago I started noticing that when Energizer batteries failed, for instance, in sets of four, that in a majority of cases, only one battery was actually bad. The others were usually within a few tenths of a volt of new (1.5-1.6 volts). I started mentally keeping track of these failures and I believe I was seeing about one in fifteen to twenty that were failing prematurely. I wish I'd had the time to do a statistically valid experiment, I did not. What a marketing scheme that would be if some number of batteries were produced with less quality control than others or........ Most people replace four (or all) batteries when (they) go bad, not checking them as I do. I believe the picture becomes clear. If you find what I did, add a comment here.

Check all the batteries when replacing them. It's possible to save a significant amount of personal resources in today's battery powered less than thinking throw-away societies.

Buy tools, etc., that plug in or better yet, are manual. Save the insane cost of some plastic bandwagon gym. AA batteries apparently repackaged into plastic case, showing expiration date of 2017, few tested cells show good voltage available, prompt shipping, good deal for standard Duracell coppertops made in China. Ordered 20pk of Duracell AA from Brooklyn Battery Works, so far the batteries seem ok but it's only been a week. I was not happy that they arrived in a small white box that WAS NOT ORIGINAL PACKAGING. The box had "20PK AA" written on it in pen... Probably won't be buying from these guys again. 20 Duracell batteries for less than $10 in today's times are you kidding me?? I got these and this price is what my local supermarkets charge for a pack of 8!!! If you need to stock up and want a great price and don't mind waiting a week for delivery this is it!!!! Used them in lights for the Ruby Mountain Relay, an overnight running relay. The lights we purchased required D batteries. They worked great. As a few other reviewers have noted, these batteries arrived in post production packaging. Either they could be from a larger container, or they could be used. I'll try to remember to update this with the results after trying some of them out. These AAA batteries have a shelf life up to 2015 (about 3 years). Those you buy in the store have a 7 year guaranteed shelf life. I'll use these within 3 years, so it isn't a big deal to me, but it might be to someone so I thought I'd mention it. Price is good compared to those in the store, so it's kind of an even trade off. Batteries were purchased in June 2012, but product received had expiration date of Feb 2012. Also they did not arrive in the advertised packaging, so am not sure if they are genuine. Could be good deal but make sure you check the dates when you receive the product. I thought the date on the bottom was the expiration date which it is not it is the manufacturing date, the exp date is on the skinny side.
These are good batteries.I purchased two packs of 9 volt batteries for my home smoke detectors. Unfortunately the batteries have a 03/2012 date stamped on the end of them and I received them in 07/2012. Quite old. Hopefully they'll last for a little while. I guess this is one of those cases of, "You get what you pay for". These were some good batteries. Pretty cheap for the quantity of them. The only thing I don't like is that some of the batteries seem to run out pretty quickly. Still, for the price, it can't be beat. Some of my battery-operated devices were getting weary and in need of a helping hand. Replacing their power source really perked them up and we're all happy now.Thought I was getting a deal with these but turn out they seem to last easily 50% less longer in my headlamp then their HomeDepot bought brothers. Disappointed!
