Digging into thousands of user reports, the Energizer Alkaline AA Batteries (20 Pack) emerge as one of the most consistently praised disposable battery options in the AA segment, earning a consensus score of 9.4/10 across platforms. While the brand markets these as “Energizer’s #1 longest-lasting MAX AA” with up to 12 years shelf life and leak protection for two years post-use, user experiences reveal both impressive endurance in everyday devices and a few cautionary tales about storage and packaging.

Quick Verdict: Yes — with caveats around packaging and specialized medical device use

Pros (User-Reported) Cons (User-Reported)
Long-lasting in toys, remotes, flashlights Occasional packaging damage or missing units
Holds charge in storage for years Not optimal for high-drain medical devices (pump users)
Leak-resistant construction Rare cases of batteries leaking/exploding in storage
Good value, especially in bulk Expiration dates sometimes shorter than advertised
Widely available and compatible Some shipments differ from listing photos
Reliable performance across brands/devices Heavier devices may benefit from lithium alternatives

Claims vs Reality

Marketing highlights a 12-year shelf life and “up to 50% longer lasting than Eveready Gold” in demanding devices. Amazon’s listing emphasizes “Powerseal technology” to prevent leaks for two years after depletion. Best Buy reviewers, Reddit threads, and ChickAdvisor posts largely confirm the shelf life claim for household scenarios — “highly praised for lasting up to 10 years in storage,” according to a Reddit user summary — but medical device users note exceptions. Trustpilot reviewer Jill S. reported: “I use them for my insulin pump and each battery lasts 2 weeks! I need these Energizer Ultimate Lithium… Max is not designed for a long time.”

Similarly, while the brand’s leak protection is a recurring selling point, there are rare but significant exceptions. Trustpilot user dnasty j. warned: “Two of them exploded in my expensive flashlight and corroded it beyond repair.” This contrasts sharply with multiple Best Buy customers praising the leak resistance, such as tsmith: “I love this brand of batteries, they last a long time!”

Cross-Platform Consensus

Universally Praised

Across Amazon, Best Buy, Reddit, and ChickAdvisor, longevity is the standout. For parents, the benefit is clear. Best Buy user khush boos noted: “My son use toys almost everyday and still the battery is going good… long lasting batteries.” In high-drain gadgets like wireless mice and flashlights, Reddit summaries report “up to 50% longer lasting than basic alkaline… ideal for everyday devices.”

Value is another recurring theme. Best Buy customer karenk appreciated finding “a large pack of batteries… cost was a good one too for all you get.” Amazon buyers often mention buying in bulk for savings, with one noting, “Work great and much cheaper than our local stores. Good value!” ChickAdvisor’s “i would buy again” sentiment echoes this — “excellent value because they last a long time.”

Compatibility is rarely questioned. From remotes to BBQ starters, users find them dependable. ChickAdvisor’s “best batteries” review states, “Perfect for my kids’ toys, and all the gadgets, they last long.”

Common Complaints

Packaging issues are a consistent frustration. Trustpilot’s tiffany v. described receiving “only 19 instead of 20 in a broken box with tape… some stuck to poorly sealed tape.” Amazon buyers sometimes get split packs instead of the pictured 20-count, with one noting, “I got two packs of 10, not what was shown… expire in 9 years, not 10.”

Leakage problems, while rare, have high impact. dnasty j.’s flashlight damage story reinforces why some users check expiration dates before use. Expired or near-expired stock can erode trust, especially when marketed as having decade-plus shelf life.

Performance in medical devices is a notable weak point. Jill S.’s insulin pump example shows that while these batteries excel in general household use, certain high-drain continuous-use devices may require lithium alternatives.

Divisive Features

Shelf life claims divide opinion. While many users confirm long-term storage viability — “still have it in my remote” after months, per Best Buy user battery — others have found shorter actual expiry dates than the advertised maximum.

Leak protection gets near-universal praise in daily-use contexts, but any incident of failure is amplified when it causes device damage. This creates a split between casual users (happy with leak resistance) and those with expensive electronics (more cautious).

Trust & Reliability

Trustpilot and Revain reports flag occasional concerns about seller reliability and stock age. Old inventory leading to leaks or explosions, as reported by dnasty j., underscores the importance of sourcing from reputable sellers. However, long-term durability stories abound. Best Buy user zecharia hl said: “Best batteries ever keeps things working for months,” and xavi added, “Good quality, long lasting and reliable batteries… convenient shipping.”

Reddit users frequently commend resistance to leakage, with summaries noting “outperforming other well-known brands” in durability. ChickAdvisor reviews consistently label them “reliable” and “best batteries ever” for household needs.


Alternatives

Two clear alternatives appear in community discussions: Energizer Ultimate Lithium and Duracell Coppertop. The Ultimate Lithium is favored for extreme temperatures and high-drain devices, lasting “up to 25 years in storage” and “several months to over a year” in wireless cameras, per Reddit summaries. Duracell Coppertop offers comparable longevity for general use but is often priced higher; some Amazon users note switching back to Energizer for better value.


Price & Value

On Amazon, the 20-pack lists around $16.47 ($0.82/unit), with occasional discounts bringing the price lower. eBay shows industrial packs for ~$14.40 plus shipping, making bulk buys attractive for heavy users. Best Buy clearance pricing ($5.99 for 20) drew enthusiastic responses, with karenk calling it “a good one… for all you get.”

Community buying tips include:

  • Purchase in bulk during sales or from trusted sellers to avoid old stock.
  • Check expiration dates upon arrival.
  • For high-drain continuous-use devices, consider lithium options despite higher cost.

FAQ

Q: Do these batteries really last up to 12 years in storage?
A: Many users confirm near-decade shelf life, especially for household items stored properly. However, some report shorter expiration dates (9 years) depending on batch.

Q: Are they safe against leaks?
A: In most cases, yes — multiple users praise the leak-resistant design. Rare incidents of leaks or explosions, often tied to old stock, highlight the need to check manufacturing dates.

Q: How do they perform in high-drain devices?
A: Solid performance in flashlights, toys, and remotes. Continuous high-drain devices like insulin pumps may drain them faster, making lithium alternatives better suited.

Q: Is bulk buying worth it?
A: Absolutely for households with frequent battery needs. Bulk packs offer significant savings, but verify seller credibility to avoid aged inventory.

Q: Do they come in the exact packaging shown online?
A: Not always; some buyers receive split packs or different packaging. Functionality remains unchanged, but presentation may vary.


Final Verdict: Buy if you’re a household user needing reliable AA power for toys, remotes, and flashlights over long periods. Avoid if your primary use is in high-drain medical or continuous-use devices — opt for lithium instead. Pro tip from community: Stock up during sales from reputable sources and verify expiration dates to maximize both value and performance.
