Duracell Quantum High-Density Core AAA Batteries 2 ea

I received a sample pack of AA Duracell Quantum batteries. I have an electronic door lock which I put them in because I need reliable batteries that won't die when I need them most. So far, I'm impressed. Generally batteries last about 6 months in that lock. As I've only had the batteries in the for a few weeks I can't say these will last longer, but so far the lock is reporting the batteries are still near full. I'd recommend these in situations where you would need batteries you can count on. (This review was collected as part of a promotion.)

I received a free sample of these batteries from Duracell for my honest review, and I really wanted to put them through their paces so I waited to try them in my "worst case" scenario. Twice a year we head deep into the bush, there is no cellular service so we rely on two way radios. The further we are apart, the stronger our radios have to be, and the quicker the batteries die. In fairness we recharge the internal batteries at camp each night, but we all carry a pack of double A's in our kit for safety and every year i've had to use mine. On day 3 I left my fully charge walkie in my pack and decided to see how long my spare radio lasted powered by only the Quantums. We were working a few miles apart, so our radios were on the high power setting, I expected to get half a day before I had to switch radios... Well after 8 hours my walkie was still going strong, and when we got back to camp I checked the power strip and I still had more than 50% battery power left! In previous years when working on battery only a few hours was all you could hope for! Fine in an emergency (as long as the other were close by) but far from ideal. On my next trip out I will have a fish set of Quantum's in my pack! The batteries preformed better than I had thought (or hoped), the power strip while old technology was nice, and I can see it being really useful when trying to diagnose if something has dead batteries or if it has other issues. They are pricey, but for I wouldn't hesitate to spend the extra $$ and put them in safety devices like our radios or emergency lights. (This review was collected as part of a promotion.)

I recently tried Duracell quantum batteries which I received free of charge from Duracell. I used them in my portable neck messaged because that gets daily use. I was very impressed with how long the batteries have lasted so far. It's been almost two weeks since I've installed the batteries and my neck messaged is still going strong. I've even removed the batteries to check how much power was left and they are about half full! That's crazy! (This review was collected as part of a promotion.)

How often do your batteries run out of juice when you aren't expecting it? Always! It's great to have an option like the Duracell Quantum so that you can test, very easily, how much power is left. I found these batteries especially perfect at the cabin--now I won't be replacing batteries on things like flashlights and smoke detectors until they actually need replacing.

As a regular gamer, batteries are a key element in my life. I was super excited to receive these batteries and was interested to see how they would perform versus the regular Duracells and Energizers that I usually get. These batteries did not lie! I tested two controllers at the same time playing co-op play with my girlfriend. Test 1 was regular Energizer vs Duracell Quantum and Test 2 was regular Duracell vs Duracell Quantum. In both test the Duracell Quantum came out on top in terms of longevity. (This review was collected as part of a promotion.)
