Quantum Battery is rated 3.2 out of 5 by 240.
Rated 5 out of 5 by from Lasted so long I forgot I had used Quantum We have a motorized deadbolt with keypad on our front door. Reality is no one uses the key, everyone in the family just enters the code to come in an out. This thing always chews through batteries. But it had been a while since I changed the batteries and it was starting to beep, indicating the batteries were getting low. I grabbed some new Duracells and pulled out the cartridge to replace the old batteries, and then noticed I had been using the Quantum battery in there. I was replacing them with regular Duracells, but made note that the Quantum battery absolutely lasted for an exceptional period of time. In the future, I will be looking for these and only wish they had them at Costco.

Rated 5 out of 5 by from Quantum - BEST battery Ever, period! I have always been a Duracell man for ALL my battery needs and since Duracell developed the Quantum, my battery use is 2-3 times better and I actually thought they would just be prettier but in fact they are the BEST batteries on the market, bar none! Thank you Duracell for providing us with an even better battery product than all previous batteries.

Rated 5 out of 5 by from Only batteries i will put in ANY of my devices. Long lasting, high quality. Why pay good amounts of money on devices just to cheap out on batteries. Only ones i will trust, they're great. I've even tried out Energizer's ultimate lithium, still prefer these.

Rated 5 out of 5 by from Yes, these really are that good I was skeptical at first about these batteries, but they really do last noticeably longer than the regular alkaline batteries we used to use. I use them in my headphones, mouse, BT keyboard, and flashlights -- things where I don't want to have to worry about replacing batteries at unexpected times. I'm sold. For me, these batteries do what they say. I definitely recommend these.

Rated 5 out of 5 by from Une charge qui dur.. Plus économique en paquets de 16 pilles, pour un usage a grande échelle.

Rated 5 out of 5 by from Nothing But Duracell. I have been a Duracell user over the past 32 years. It started back when I was a Volunteer Fireman for my Home Town and Continued when I went into the Air Force as a Fire Protection Specialist. I have always trusted Duracell in my flashlights and passive life protection device. They never failed me. even though it has been 22 years since I have been able to serve as a fire fighter or in the military. Its nice to know that Duracell keeps standing strong through out all these years.
