Test results: Price vs. Battery Energy, Decent Value but Die Faster
on May 13, 2015
I like AmazonBasics products, so I was excited to see these batteries. To find out if they were a good value, I looked up data online. Bottom line:
-- For flashlights, toys, and steady drain devices, you'll be better off buying Rayovac Alkalines here on Amazon.
-- For cameras and photo flashes, Duracell Coppertops will be better.
Here's why: Rayovacs cost a little bit more per battery, but they hold more energy than these AmazonBasics batteries. As a result, the final price per amount of power is about the same. You just won't have to change batteries as often.
Those Rayovacs work best in steady drain devices, but not so well in cameras or flashes. For those high drain devices, Duracell Coppertops hold up better and end up being cheaper.
Battery Ninja tested these AmazonBasics AA's in toothbrushes I did some calculations and found that these batteries offer a reasonable price per unit of power (mWh), but that they do not carry as much energy as others. The test results show that these batteries will run out faster than others, at least in the toothbrushes. There were no test results vs. digital cameras, photo flashes, or toys, so I'm extrapolating that these will perform like Rayovacs, not like Duracell Coppertops.
So, the only data to compare here is the toothbrush test. For energy delivered, these AmazonBasics batteries cost about the same as Rayovac batteries but will die sooner. To say that another way, these batteries cost less, but also deliver less power.
Both Rayovac and Amazon Basics are better than Energizer batteries, which appear to consistently give less power and still cost more. I guess the money goes to the Energizer Bunny.
Duracell Coppertops will last longer in flashlights, toys, and toothbrushes, but cost a little bit more per unit of power (mWh). On the other hand, they hold up better in cameras and similar electronics. They're probably the best all around battery. So, if you don't like changing batteries and a willing to spend a tiny bit more, Coppertops are a good way to go.
Finally, the best value battery is interesting: it is the Costco Kirkland Signature. Battery Ninja's results show that and so do the tests from Consumer Reports. You can buy those Costco batteries here on Amazon, but the price is higher than you'd get at the club. Of course, I'm not a Costco member, so it doesn't matter to me... but buying them here on Amazon is not a good value.
