List of battery brands that include the most reliable models available. Top battery brands include those from major manufacturers of batteries including Energizer, Duracell, Panasonic and more. In strict terms, a battery is a collection of multiple electrochemical cells, but in popular usage battery often refers to a single cell.
Ranking brands is different from ranking batteries, of course, and it turns out to be a lot more complicated. You cannot necessarily trust that every battery made by one brand is automatically better than every comparable battery from any other given brand.
Still, the top three battery makers are responsible for two thirds (66%) of the total battery deployment, which highlights the importance of scale in this business, in order to have the most competitive product on the market. Panasonic, once upon a time a leader in the automotive EV business, has continued its slow slide down the table.
Amazon AAA batteries emerged as the most reliable during our discharge test, exhibiting consistently repeatable results across three different runs and boasting the longest average discharge time at 28 minutes, 32 seconds. Moreover, if you're considering buying in bulk, this option is, by far, the better choice.
Still, we must acknowledge the good ones, and some of the more highly regarded brands in the Lithium-ion rechargeable battery space include Samsung, Sanyo/Panasonic (who also make good 1.2v Li-ion rechargeables), LG, Sony, Shockli, Keeppower, LiitoKala, AWT, Tensai, Windyfire and Efan.
Finally, Sunwoda is greatly benefitting from the growth of the startup Leap Motor, which it is the main battery supplier for. With the EV market continuing to grow fast, and average battery size increasing, expect the battery market to continue growing even faster, with +/-50% growth rates likely in the next couple of years.
