āContains 4Ć Power Boost ingredientsāā¦
Yeah? Does anyone here have any idea what that actually means? Sounds loke they are saying these batteries have 4 times the MAH capacity, but that is also clearly not what they are saying. So, that is what they want ignorant and gullible people to think when they see this? But they can step back, put their hands up, and say āWhoa, whoa. Uh, thatās not what we saidā. Slick. Funny.
From Google AI:
More Power Boost: Contains significantly more of Duracellās patented active ingredients for enhanced performance.
Right on. I appreciate you looking into it. But let me ask; do you think they put 4 times the active ingredient in these, compared to their average/standard batteries of the same size?
That would be a question for Duracell. 
I ordered some of these for my EDC pocket flashlight that uses just one AA battery thinking it would be nice to have maybe a little extra life in it. But it metered out to be the same as an off brand AA I had. I guess time will tell but Iām not holding my breath. BOZ
well I just googled customer reviews for these batteries and mostly favorable reviews. Main downside listed was 'āsome reports of premature leakage or damage from corrosionā But then again opinions(reviews) are like a__ _____, everyone has one., as the saying goes. Guess we should look for a reviewer that uses these batteries along side other brands in a test to see how long they last in different things. Do they really make lights brighter as some claim. Let us know if anyone finds such. BOZ
PS the ones WOOT sent me were made in 2022. Duracell says that they have a 12 year shelf life. If you plan on putting these back for the end of daysā¦for less that $2.00 more you can get these at Walmart that were made this year. That is if 4 extra years matter. But Iām pretty sure most will be using them sooner than later.
Hey there fellow Wooter, I found someone currently using these batteries as a comparison test to the name brand which they normally use.
So,
If you would, please, let us know how they seem to be working for you? Can you notice any brightness boost or difference?
How much use does your EDC get & how is the duration with these going to compare? What is your EDC? How bright is it? Those last 2 questions are not from a flashlight nerd/junkie/hoarder. 
TIA
Have a Wootifly Wootiful Day!
I bought these, i put them in my Yale Door lock and they only lasted one month. Mind you we have auto door lock and all the fancy stuff turned off, so the batteries are just sitting. The ones i bought off amazon lasted about 5 months. I probably would never buy them off woot again.
These, too, ship from Amazon.
