The battery aisle is a confusing place and if you’ve ever found yourself wondering if brand name batteries are worth the extra cost, you’re not alone. Wired has put together a comparison between expensive batteries and dollar stores batteries that answers the question.
According to their study, name brand batteries from Duracell and Energizer last over twice as long as dollar store batteries. However, when they broke down the cost to energy ratio, all the batteries are essentially equal. The exception is that you have to replace dollar store batteries more often, but since they’re cheaper, it balances out. What does this say about choosing batteries? Wired suggests:
It depends on what you are using it for. Suppose that I was using these batteries for a flashlight. In this case, it wouldn’t matter too much which battery I used. If I used the cheaper DG, I would just have to replace the batteries more often. However, suppose that I am using the batteries for my Wii remote or my awesome Syma indoor RC helicopter (these really do fly nice). For these electronic devices, if the voltage drops too low they might not work properly.
