Quantum Battery is rated 4.016806722689076 out of 5 by 119.
Rated 3 out of 5 by from Good Battery for Remote Controls The performance curves of this battery are indicative of one that functions well in remote controls (tv, sound system, dvd player etc.). However, its constant current curve at 200 mA is nearly identical to the standard coppertop, where 1.2 volts is reached after a service time of roughly 6 hours. Thus, due to its increased cost relative to the coppertop, I would not recommend it in devices such as digital cameras, flashlights, or video game controllers. While its performance can be rated excellent for remote controls, I can only give this battery a 3-star rating, as it appears that Duracell is having issues assuring the quality of this product.

Rated 2 out of 5 by from D size battery Leaks I had a brand new 4 pack of D sized batteries, used them 1 time, for about 5 minutes. Put them away and a month later all of them had leaked and are dead. About 6 months ago I had a 3 cell Mag Flashlight and I had the LED upgrade installed. Used this for maybe 10 minutes, went to use it again in a week and the batteries had leaked and ruined the flashlight and the Expensive LED upgrade that I had put in it. I was so upsetf that I threw it in the trash, I did not even think about a warranty at the time. I wished I had sent it in to be replaced. Now I am out about $35 due to Faulty duracell batteries.

Rated 5 out of 5 by from Satisfied with these batteries I have not had any problems with these batteries. I saw their review in Consumer Reports and bought some. There have been no issues of premature failure. Being an engineer and scientist, I am not prone to making unsubstantiated assumptions. I have not done a study on whether these Quantum batteries last longer than the Coppertops, but I also have not noticed that they do not. I have no reason to believe that Consumer Report's comparison of these batteries to other types and brands was flawed.

Rated 4 out of 5 by from Duracell Quantum Batteries we have been testing AA duracell quantum batteries courtesy of duracell for about a week now. great source of energy for our infant toys. after a week the batteries are still going stong. one of the highlights about this particular battery is the powercheck feature on each battery. there is a button that you can push to see how much energy is left in each cell. unfortunatly the power cgeck in 2 of the 4 cells we received did not work. the batteries were all good and we are still using it but the power check feature was only good in 2 of the 4. overall i would use quantum batteries again solely for the fact that they are duracell and reliable.

Rated 1 out of 5 by from More like the world most weak batteries! I bought a big pack of batteries and used them for my brand new Xbox one... Every time I would go to play they were dead! I also put them in the tv remote. I bought them in January.... And they are dead already.... Smh the off brands work better then these over priced crummy waste of money and product. I mean why even make them they suck so much they shouldn't even be able to be produced anymore... I want my money back I bought the biggest pack 24 I think idol but there was a lot... And they only lasted me this long engizer lithium is the way to go those last years! I can't believe that these are supposed to be the competition these are the worst batteries ever!!! Ppl do the world a favor and get the real ones, that keep going and going and going!

Rated 4 out of 5 by from Powercheck NO Alkaline Batteries Duracell Quantum NO Alkaline Batteries are a great solution to making sure your batteries always have life. I really appreciate these batteries after a night of listening to the smoke-carbon monoxide detector dinging and talking stating battery life low. How do you figure out which one the noise was coming from. The powercheck batteries will come in handy. All you do is press both ends and the life of the battery shows up. Full of life or just plain dead. There is a 10 year guarantee in storage .The only thing that would be better is if I did not have to press both sides to figure this out. I received this product for free for my honest unbiased review.

Rated 1 out of 5 by from Unanimously Poor Rating!!! We purchased large packs of AA and AAA at Sam's, and tried them in clocks, flashlights, remote controls, etc. THEY DON'T LAST and SOME DIDN'T WORK AT ALL. Ruined an automatic air freshener, as batteries didn't have enough power to propel the spray from the dispenser. Spray collected inside the dispenser and ruined the piece of furniture it was sitting on when it leaked out. We are planning to take them all back to Sam's and will never purchase them again!!!

Rated 5 out of 5 by from Takes the sting out of life I used these Duracell quantum batteries to power a black light flashlight. I live in the foothills of California where scorpions abound. Since they fluoresce bright green under black light they're much easier to spot. When I first received these from Duracell I figured batteries are batteries, right? I swapped out the store brand I was using for these and what a difference! The light was noticeably brighter and the flashlight has been used every night for several weeks and hasn't dimmed. These Duracell quantum batteries are powerful and long lasting and have helped keep my family scorpion-sting free for weeks! Thanks Duracell!
