i know it frustrates me to hell.Ī good rule of thumb is to get industrial grade alkalines eg, energizer industrials. also, the cheaper batteries dont give you the run time per battery as cheaper ones, so even if buying a pack of cheaper ones for the same price as not as many better ones, who really wants to be changing batteries in their xbox controller every couple of hours instead of every 6 to 8. BUT, not every device is happy to run at 1.2 – 1.4 volts (and its multiples) some devices end up losing out on over a volt with 4 or more batteries. Yes, rechargfeable batteries offer a better cost/lifespan/suage solution. This story has been updated since its original publication.
#2032 BATTERY DOLLAR TREE FULL#
You can read Allain’s full breakdown at Wired. Those dollar store ones will likely work just fine. If we look at the price for Duracell AA batteries at somewhere like Officeworks where a 16 pack is $21.99 ($1.37 each) and compare to the ALDI ones, where in the past they have had 20 packs go for as little as $7 (0.35c each), there is a clear discrepancy in how much you might have to dole out for your energy.īottom line? It’s not always worth going for the more expensive brands if you’re just looking for a quick fix. In Australia, a survey by Canstar Blue of consumer satisfaction with batteries in 2017 showed that Duracell was rated the best, but that ALDI Activ Energy batteries were considered the best value for money. There is one issue though: the cheaper kind also have a lower voltage, so Allain cautions that some devices may not work as well - or nearly as long - as they would on brands like Energizer or Duracell. The more expensive ones have more power, sure, but for the same amount of money you get more batteries in the dollar-store pack. When you analyse the three brands side-by-side, it becomes clear that the money-energy density is very similar. Rhett Allain suggests that when making a purchase, you are really just buying energy and thus, you can quantify the ‘money-energy’ density of the battery: The energy divided by the cost per battery.
However, the real gold lies in the notion that the expensive batteries are not worth the extra cost. Somewhat unsurprisingly, the more expensive brands, Duracell and Energizer, were shown to have greater power, more energy and last longer than the cheaper dollar store batteries.
Some incredibly astute investigative work over at Wired takes a deep dive into the ‘quality’ of cheap, dollar store batteries and compares them with two of the most well-known battery manufacturers - Energizer and Duracell.
