Battery Life is an important consideration when purchasing a phone. It is a great nuisance to buy an expensive phone only to realize that it must be plugged into a power supply several times a day due to poor battery life.
In this blog, we show the top Samsung phones with the best battery life as well as their prices on popular online shopping sites. There are also sample customer reviews also to check so as to give an informed decision.
This battery is in demand constantly I’ve always used these batteries they do last a long time. It’s cute when a little person needs a battery and knows just the person to ask.
I used to always buy Duracell but I noticed that they had a bad habit of leaking so I thought I’d try theEverReady Rabbit. Good to buy in bulk less expensive and it saves the irritation of needing a battery in the middle of a power outage.
I wouldn’t buy any other battery. Best there is. Using them ever since they came on the market. Copperas are long lasting, clean, excellent.
when I test this battery show 1.7 volts most of them goes to 1.6 volts so here is from begging really strong battery enjoy good product .
I took all of the batteries out and put them into a battery daddy so they don’t get separated since the batteries are wrapped in a soft plastic wrap material, not a hard plastic like you might find at a box store in person. These batteries were the best price per battery that I could find with a reputable name brand and they do last a very long time. Highly recommend if you go through a lot of double A batteries and need a reliable battery.
We have so many things that take batteries seemed like I was continually buying the little six pack. This was so worth it will purchase again
When all is said and done, chances are, if your flashlight, or device isn’t running Duracells, the power is fading. We choose Duracell Optimums for all our AA gear!
I never had a problem with Duracell or Energizer batteries. I’m sure you can find online a graph online comparing the longevity of the batteries but I find both brands reliable. These batteries work great.
I ordered a 12 pack for a few mini LED flash lights that were either dead or on their way. I replaced the first set, I turned the light on and it wasn’t very bright. I double checked that they were in correctly and then installed another new set of three batteries. This time it lit up properly. I ended out swapping the individual batteries of the first set on at a time and found one was dead. I went through and test the other eleven batteries and found one more bad one. I didn’t make a full return as the other 10 are fine. I don’t want to go through the hassle. I wrote this in case someone experiences the same thing and that just swapping our one battery at a time could probably fix it.
As far as batteries go, I am still a firm believer in Duracell’s lasting power over other brands. Not sure if this holds true anymore or not since I do not usually purchase other brands. Seem to work very well and last long in remotes, laser pointers, and the like.
I use for a wireless microphone. There’s a noticeable difference in the longevity of these batteries. I will buy again and I do recommend..
Received at the front end of 2023, these batteries are dated thru 2029- showing a shelf life beyond 5 years. These are fresh, and not old stock being dumped at bargain prices. Thats what ever-ready publishes for this ‘industrial grade’. I use AAA batteries in professional sound wireless microphones, TV remotes, flashlights, outdoor thermometers… I also appreciate the waste-free packaging. (I ordered a quantity of 32 and received a brick of 24, plus a retail blister pack of 8.I will purchase again!
I originally ordered this product based off of the 100% recyclable plastic free packaging. However these batteries do come in a cardboard box with plastic wrapping with four batteries each. While the photo advertising that it’s plastic free does have a caveat that this is “Excluding seals on selected larger packs” I assumed that to refer to the variety pack, not the 32 count that I ordered.Still, they came earlier than expected and they work fine. The packaging used from the Amazon distribution center (I’m assuming, since I received another item alongside this) was at least 100% recyclable paper. The cardboard box these come in is easier to get into and far less frustration. So while I’m disappointed that there was plastic inside the box, I’m still rating a 4.
Batteries are difficult to test for a consumer. I have seen in the past (in my own, informal, unscientific testing) that some “Pro”-labeled ones actually under-performed their “regular” counterparts. So, allow me to share with you a battery test I made between the Duracell CopperTop, Quantum, and Optimum batteries, then compare them to the Energizer Max and Ultimate Lithium. Finally, I will compare them to the rechargeable, Panasonic Eneloop Pro. This was likely my most expensive battery test I have ever undertaken, and because they are one-time-use batteries, not the most eco-friendly. I apologize for the latter!PROS- Lasted long, but surprisingly not much better than the CopperTop ones- Slider packaging holds the batteries together better, though I recommend dedicated, plastic battery holders for better and more space-efficient storageCONS- Costs more than Duracell’s other lines- Not worth the extra premium for a slight increase in battery lifeTESTINGI tested the batteries by having 3 of them each used in an Imaginarium RC train and having it go around a flat, circular track. Each time it would pass a specific point on the track, a sensor was hit to track what time it completed a loop. In the end, I had an Excel spreadsheet that showed the number of loops that were made. From there, I calculated the start time and the last time it hit the sensor. Keep in mind, however, that many factors could affect a battery’s performance. Some are made better for one type of use, but would fare worse for another.Surprisingly, the Duracell CopperTop slightly outperformed the Quantum, whereas the Optimum ran longest between the three.MARKETINGDuracell markets the CopperTop being less premium than the Quantum, and that in turn less than the Optimum. Visually, that can be represented as:CopperTop < Quantum < OptimumACTUAL RESULT (with the RC train)Quantum < CopperTop < OptimumThis showed that paying the extra pennies for the Quantum over the CopperTop was not worth it. The Optimum, with just a slight advantage in battery life over the CopperTop did not fare much better either. So, from a Duracell perspective, I would continue to stick with the CopperTops for best value and decent battery life.Next, I threw in some Energizers. The Max and one of my favorites, the Ultimate Lithium.- Max outperformed all 3: CopperTop, Quantum, and Optimum by about 60%.- Ultimate Lithium (which is not Alkaline, by the way), nearly DOUBLED the battery life over the CopperTop! This was not surprising to me as this line is a BEAST (with the gigantic price tag that comes with it.)Visually, the RC train result was:Quantum < CopperTop < Optimum < Max (+60%) < Ultimate Lithium (+110%)Finally, I wanted to see how the RC car would work with my favorite, rechargable batteries that I depend on for my professional photography work: Panasonic's Eneloop Pro. The Eneloop are designed to hold 70% of their charge for up to 10 years, and for wedding photography, that is an important factor as I cannot afford taking out batteries that may not be able to provide the power I need at a moment's notice.The result? They did average. Visually:Quantum < CopperTop < Optimum < Eneloop Pro < Max < Ultimate LithiumPrice wise, the Eneloop Pro and Ultimate Lithium afford a VERY high premium. They are EXPENSIVE. If you asked me which batteries I recommend over the other, the answer is: it depends.Some devices work better with Alkaline or Lithium than NiMH rechargables. Alkalines provide a higher, initial voltage for more power, are cheaper, but once they hit a certain discharge threshold, they become useless very quickly with certain types of devices. With the Eneloop Pro, they provide a longer discharge life, can be used for a longer, sustained period, and of course, be recharged hundreds of times. So, what does that mean?I would like to re-iterate that I am not a professional, lab-certified, battery tester. Your own results may vary from my own, informal, unscientific testing using a RC train.For RC cars, the Duracell Alkalines are my recommendation — specifically, the CopperTop. For photography equipment and flashlights, I go with the Eneloop Pro for the long battery life and their ability to hold their charge for a prolonged time. For critical devices that require the longest battery life, such as fire alarms, I'd go with the Ultimate Lithium.With all that said, among the CopperTop, Quantum, and Optimum line of Duracell batteries, I'd stick with the less expensive CopperTop for its better cost-to-life ratio.
