The Best Prime Day Battery Deal You’re Probably Ignoring

Prime Day 2025 is here from Tuesday, July 8 to Friday, July 11, and Lifehacker is sharing the best sales based on product reviews, comparisons, and price-tracking tools. 

New to Prime Day? We have a primer on everything you need to know. Sales are accurate at the time of publication, but prices and inventory are always subject to change.

Prime day might be best know for deals on cutting-edge consumer electronics and self-stirring coffee mugs, but it’s also a good time for totally non-sexy, completely solid purchases, like these Duracell batteries.

Look, I know you have a million remote controls, game controllers and other bric-a-brac that thirst for power like so many tiny Kublai Khans, so yes, you do need a 56-count bundle of both AA and AAA batteries, especially since they’re 35% off. Specifically, this bundle has 28 AAA batteries and 28 AA ones, so you get a good amount of both.

They’re from Duracell, so you get that classic copper-top look that says, “Yeah, I’m a good battery,” but isn’t all braggy about it. According to the listing, they’re “formulated with Power Boost ingredients,” which is a real thing, I’m sure, and they come in a “re-closable pack for a quick, easy access and organized storage.” I wish everything came in a re-closable pack for easy access and organized storage. Life offers no guarantees, but Duracell does: these bad boys are guaranteed to last 12 years in storage. You might not last 12 years, so what are you waiting for? It’s time to take charge of your life and buy these batteries.

Looking for something else? Retailers like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

• Walmart’s Prime Day competition sale begins at midnight on July 8 and will include deals up to 50% off. It’s an especially good option if you have Walmart+. 

• Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.

• Home Depot extended its 4th of July sale through at least July 9, competing with some amazing deals of its own. It’s an especially good option if you’re looking for power tools, appliances, or outdoor equipment.
