![]() The good news is: There are other people who are into batteries almost as much as we’re into carabiners. And although this “study” by BitBot was conducted in the U.K. And sadly, our lack of chemistry background makes comparing batteries more difficult (and noticeably less interesting) than comparing climbing gear. So too could the Duracell engineers modify the compression and composition to improve the capacity.īut if this is the case, Duracell isn’t readily providing the information to help the consumer clearly identify how the improvements were made, or what they are. If this is similar to CAMP stating that the Evo Tricams are significantly better than the previous version due to some simple rearrangements of the current materials: moving the stitching on the sling to act as a stiffener, and shaving off material on the side of the cam to add another placement option, then I am totally into it. The official Duracell website says that the Hi-Density Core™ is a “proprietary compression process and unique formulation of ingredients…With more power boosters and improved energy flow throughout the battery.” I’m not sure if “power boosters” is the technical term used by Duracell’s engineering team, but we can’t find any data to describe what this actually means or how it improves real-world performance. So the entire “Quantum leap” of power must come from the Hi-Density Core™. Admittedly, I have often wished all batteries had this feature, but I don’t understand its relation to increasing power. This is a little disappointing considering the Quantum leap of technology includes the PowerCheck™ strip, that states how much battery life is left, a technology Duracell introduced in 1996. Combined with a Hi-Density Core™ and PowerCheck™, it’s a Quantum leap in battery power.” The Quantum battery is officially billed ( on a Duracell press release) as “A revolutionary advancement in battery technology. Between the months and years from our initial test, nearly all our Duracell batteries have leaked and corroded the few devices that we weren’t running on rechargeable batteries. The bottom line of the 1-star reviews was: don’t spend the extra cash on Quantum’s and stick to the tried-and-true CopperTops. The 1-star Quantum users, most of whom were not provided free batteries, chided the life span, leaking issues, and some DOA incidents despite their 10 year guarantee. ![]() The top 5-star review cites the Duracell Quantum as the top rated Consumer Reports alkaline battery, just behind Energizer’s Lithium model. ![]() When we checked Amazon, the AA Quantums have 25% one-star reviews while not quite half, 47%, are five-star ratings. There are many consumer reviews that suggest despite their additional cost, Duracell Quantum batteries may not be the breakthrough in power that is advertised. To make sure we wrote a comprehensive review, we did a little a lot of digging and found that we don’t know jack about batteries, nor does a majority of the population. I do think it’s rad that Duracell is supporting Kevin Jorgeson and putting out some other pretty good commercials.īut enough of the no-data-to-back-it-up stories. Like Kevin, as his Duracell commercial implies, my parents raised me on Duracell. Quick update and spoiler alert 2 years after writing this post: I am no longer a Duracell fan. Whatever the reason, I’ve been a Duracell loyalist even though I’ve never done a quantitative study. Perhaps it’s their sleek look I trust or maybe it’s because my parents had an Energizer battery case that was always full of Duracell batteries. When sliding batteries into my avalanche beacon or replacing batteries in my headlamp for a pre-dawn climb, Duracell has been my go-to brand for years. In the past I have been biased toward Duracell batteries. We tested out all the goods, and here’s our battery story: Following his success on the Dawn Wall project, Kevin Jorgeson partnered with Duracell to create a “Perfect Pack” of promotional goodies including a plethora of AA and AAA batteries, a small climbing pack, and a super burly headlamp.
