Powermax 24-Count Double AA Batteries, Ultra Long Lasting Alkaline Battery for Home and Office, 10-Year Shelf Life, Reclosable Packaging

Why I picked up the Powermax AA 24‑pack

Running a home office means I burn through AA cells steadily—remotes, wireless mice, LED flashlights, a label maker, and a couple of kids’ toys that seem to exist purely to test battery endurance. I grabbed the Powermax AA 24‑pack to see if a mid‑priced alkaline could serve as a dependable “load and forget” option without paying a premium for the household name brands. After several weeks of mixed use, I have a good feel for where these shine and where they fall short.

Packaging and first impressions

The reclosable packaging is a thoughtful touch. It’s a lightweight plastic case that’s easy to toss in a drawer and pull from as needed. My only complaint is the latch—it closes, but it’s not exactly confidence‑inspiring if you’re moving the case around a lot. Stored flat in a drawer, it’s fine; tossed in a tool bag, it may pop open. Each cell is clearly labeled AA/1.5 V alkaline with a long expiration date (mine were marked a decade out), which aligns with the claimed 10‑year shelf life.

Out of the box, open‑circuit voltages on a random sample were in the 1.60–1.61 V range—what I’d expect from fresh alkaline cells. No cosmetic defects, no loose wrappers, and consistent labeling across the pack.

Everyday performance testing

I ran the Powermax AA across low, medium, and higher‑drain scenarios to mimic normal household use.

• Low-drain (TV remote, wall clock, wireless mouse): This is where alkalines typically cruise, and these did exactly that. The remote and clock show no signs of weakening after weeks of use. In a Logitech wireless mouse used 6–8 hours a day, the battery indicator sat comfortably in the top third after three weeks, comparable to other mainstream alkalines I’ve used.

• Medium-drain (LED lantern, motion-sensing closet light): In a 2xAA LED lantern drawing roughly 250 mA total, I clocked just over 10 hours before brightness dropped to the “dim but usable” zone. That’s right in the pocket for an everyday alkaline. The motion light, which spikes intermittently, ran as expected for several weeks without surprises.

• Higher-drain (game controller, compact LED flashlight): In a wireless game controller that tends to be unforgiving to weaker cells, I measured about 25–30 hours of play across two cells, depending on rumble usage. That’s a notch below premium alkalines or lithium AAs, but acceptable for the price. In a 1xAA compact flashlight on high, the initial output was strong and maintained usable brightness for around an hour before a noticeable drop, transitioning to a softer, lower mode for a few more hours. Again, akin to mid‑tier alkalines.

If your use case is mostly remotes, clocks, and other low‑drain gadgets, the Powermax AA feels indistinguishable from better‑known brands. If you’re pushing them hard—think gaming marathons, bright flashlights, or photography flashes—you’ll see faster voltage sag and shorter runtime than with premium alkaline or lithium options.

Reliability and leakage

No leaks, swelling, or hot cells in any of my tests. It’s early days for long‑term storage claims, but the cells arrived fresh and sealed, and the chemistry is standard alkaline with no mercury or cadmium. As with any alkaline battery, I recommend:

• Don’t mix old and new cells.
• Don’t leave batteries in devices that sit unused for months.
• Store in a cool, dry place (not a hot garage).
• If you need absolute leak resistance for long storage in a device, consider lithium AA.

These simple habits extend the life of any alkaline and reduce the risk of corrosion.

Shelf life and storage

The 10‑year shelf life claim is in line with modern alkalines. I can’t verify a decade, but I checked manufacturing codes and expiration dates; mine were appropriately far out, and the cells tested “fresh” by voltage and performance. For emergency kits and infrequent‑use devices (like that rarely used camping lantern), a 24‑pack with a clear label makes it easy to rotate stock and keep a few on hand without worrying about near‑dated cells.

Environmental notes

Powermax notes the cells contain no mercury or cadmium, which is typical for today’s alkalines. That doesn’t make them landfill‑friendly—alkalines should still be recycled where local programs allow. If you’re burning through AAs in high‑drain gear, consider moving those devices to NiMH rechargeables; you’ll save money and waste long term while keeping alkalines for remotes, clocks, and emergency backup.

The small stuff that matters

• Consistency: Every cell I tested performed within the expected band for a mid‑tier alkaline. No early duds in the bunch.
• Contact quality: Clean terminals, no film or residue, no fit issues across devices.
• Temperature: In cool outdoor use (around 40°F/4°C), output dropped more quickly—as expected for alkaline chemistry. If you need cold‑weather reliability, lithium AA is still the right choice.

Value

The Powermax AA 24‑pack sits in a very comfortable price/performance spot. Cost per cell is typically lower than name‑brand alkalines, and the real‑world performance tracks closely in low and moderate drain devices. If you’re shopping purely on runtime for high‑drain tasks, premium alkaline or lithium cells will outlast them—but you’ll pay for it. For everyday household and office use, the value proposition here is strong.

Where they fit—and where they don’t

Use these if you want to:

• Stock a drawer for remotes, clocks, toys, and LED accessories.
• Keep an emergency stash that won’t be near expiration anytime soon.
• Power a wireless mouse, keyboard, or presentation clicker reliably.

Consider alternatives if you:

• Rely on high‑drain devices (high‑output flashlights, camera flashes, motorized gadgets). Lithium AA or quality NiMH rechargeables will perform better and may be more economical over time.
• Need batteries for extreme temperatures. Lithium handles cold and heat better than alkaline.
• Want to minimize waste in heavy‑use scenarios. Rechargeables are the sustainable path.

What could be better

• The reclosable case needs a stronger latch. It’s fine for a desk drawer, less great for a go‑bag.
• In high‑drain use, these trail top‑tier alkalines by a modest but noticeable margin. Not a flaw per se—just know what you’re buying them for.

Bottom line

The Powermax AA 24‑pack hits the mark for dependable, everyday power. Fresh cells, consistent performance, and a long dated shelf life make them easy to recommend as a household staple. They’re not trying to dethrone premium alkalines in the heaviest loads, and that’s fine—most of us don’t need that level of performance in remotes and clocks. What matters is that they work predictably, don’t leak in the short term, and arrive organized in a case that mostly does its job.

Recommendation: I recommend the Powermax AA 24‑pack for general home and office use. They offer solid reliability and good value for low to medium‑drain devices, with the bonus of a long shelf life for emergency kits. If you primarily run high‑drain gear or need top performance in harsh conditions, step up to lithium AA or a quality NiMH rechargeable setup. For everyone else, this 24‑pack is an easy, sensible buy.
