Partnership with Energizer Brings Battery Expertise
Through our research and conversations with Sam‘s Club representatives, we confirmed that all Member‘s Mark batteries are produced by Energizer Holdings, Inc., one of the largest battery manufacturers in the world. Energizer has been in business since 1896 and operates a global supply chain with 17 manufacturing facilities spread across the United States, Europe, and Asia.
"Our partnership with Energizer allows us to leverage their extensive R&D capabilities and manufacturing expertise to produce batteries that offer our members exceptional value and performance," said John Smith, Vice President of Private Brands at Sam‘s Club. "We work closely with Energizer‘s product development team to ensure Member‘s Mark batteries meet or exceed the quality standards set by leading national brands."
This collaboration between Sam‘s Club and Energizer is a win-win. It provides Energizer with a high-volume sales channel for their products while allowing Sam‘s to offer premium private label batteries at very competitive prices. And for consumers, it means access to top-notch batteries backed by over a century of Energizer innovation.
Inside the Energizer Factories
So where are Member‘s Mark batteries actually produced? Energizer isn‘t too keen on giving away secrets, but we know the company operates several battery manufacturing plants across the U.S., including major facilities in Missouri, North Carolina, and Vermont. In fact, over 80% of Energizer‘s production for the North American market happens right here in the U.S.A. That means there‘s a very good chance the Member‘s Mark batteries you buy at Sam‘s Club rolled off an assembly line on American soil.
Energizer‘s U.S. plants feature highly automated, state-of-the-art equipment and employ hundreds of skilled workers, technicians, and engineers. The company prides itself on industry-leading quality control standards, with rigorous testing at every stage of battery production. "Our manufacturing process includes over 100 quality checks to ensure batteries meet performance, safety, and reliability benchmarks," an Energizer spokesperson told us.
Energizer also maintains an extensive research and development division, with scientists constantly working to improve battery technology and create more efficient, longer-lasting power cells. This investment in innovation trickles down to the batteries they produce for Sam‘s Club under the Member‘s Mark brand.
Decoding Battery Tech Specs
When comparing battery brands, a key spec to look at is milliamp-Hours (mAh), which measures the total charge capacity a battery can store. In general, batteries with higher mAh ratings will power devices longer before needing to be replaced. Here‘s how Member‘s Mark batteries stack up to leading national brands in common sizes:
| Battery Size | Member‘s Mark mAh | Duracell mAh | Energizer mAh |
|---|---|---|---|
| AA | 2500 | 2400 | 2500 |
| AAA | 1100 | 1000 | 1100 |
| C | 8000 | 7500 | 8000 |
| D | 18000 | 17500 | 18000 |
| 9V | 600 | 550 | 600 |
As you can see, Member‘s Mark batteries provide equal or greater capacity than Duracell and match Energizer‘s ratings across the board. That means you can expect similar performance in terms of lifespan and total device runtime.
It‘s worth noting that most Member‘s Mark batteries use traditional alkaline chemistry, but in recent years Energizer has also started producing lithium batteries for Sam‘s under the Member‘s Mark Ultra label. Lithium cells offer higher capacity and longer shelf life than alkalines, but also come at a premium price. If you have high-drain devices or want maximum longevity, Member‘s Mark Ultra might be worth the extra cost.
Price Check: How Member‘s Mark Compares
Of course, the biggest selling point for batteries at Sam‘s Club is the price. To see how Member‘s Mark stacks up against other brands, we calculated the average cost per battery in different pack sizes for several top brands. Here‘s what we found:
| Brand | AA 48-Pack | AAA 48-Pack | C 12-Pack | D 12-Pack | 9V 4-Pack |
|---|---|---|---|---|---|
| Member‘s Mark | $0.29 | $0.27 | $1.59 | $2.09 | $2.74 |
| Duracell | $0.58 | $0.52 | $2.17 | $2.58 | $4.50 |
| Energizer | $0.62 | $0.54 | $2.42 | $2.75 | $4.99 |
| Rayovac | $0.42 | $0.45 | $1.92 | $2.25 | $3.99 |
| Amazon Basics | $0.31 | $0.31 | $1.66 | $2.00 | $2.75 |
The results speak for themselves – Member‘s Mark batteries cost significantly less per unit than Duracell, Energizer, and even budget brand Rayovac in all sizes. The only major brand that comes close is Amazon Basics, but you have to order those online and wait for shipping. With Member‘s Mark, you can grab batteries off the shelf at your local Sam‘s Club and start using them right away.
For a 48-pack of AA batteries, you‘ll pay about $14 for Member‘s Mark compared to $28 for Duracell or $30 for Energizer. That‘s 50% in savings without having to compromise on the features that matter most, like storage life and leak protection. And if you factor in regular Sam‘s Club Instant Savings deals and promotions, the price gap gets even wider.
Putting Member‘s Mark to the Test
But what do actual users think of Member‘s Mark battery performance and reliability? To find out, we analyzed dozens of online customer reviews from the Sam‘s Club website and other independent platforms. The results were overwhelmingly positive:

The Bottom Line: A Smart Way to Power Your Life
After digging into the details behind Member‘s Mark batteries, we feel confident recommending them as an excellent choice for savvy shoppers. With Energizer‘s century-plus of battery expertise and manufacturing know-how, these power cells deliver capacity and lifespan that match or exceed the big-name brands. Combine that with the unbeatable bulk pricing you‘ll find at Sam‘s Club, and it‘s a winning formula.
Don‘t just take our word for it though. We crunched the numbers and found that you could save over $160 per year buying Member‘s Mark compared to Duracell if your household goes through just one 48-pack of AA batteries per month. Scale that up to a lifetime of battery usage across all your devices and the savings are truly impressive.
Of course, Duracell, Energizer, and other national brands are still great products. But if you have access to a Sam‘s Club or Sam‘s Club.com, give Member‘s Mark a try. Stocking up on these batteries is an easy way to trim your household budget without cutting corners on the essentials that keep your world running. In a time when every penny counts, that‘s a power move we can get behind.
