Energizer Ultimate Lithium AA Review: Long Life Verdict
Some Best Buy shoppers say these cells power their Blink cameras for over a year without replacement. Energizer Ultimate Lithium AA Batteries (8 Count) earn a rock-solid 9.5/10 for longevity and reliability, with near-universal praise despite a premium price tag. A verified Walmart buyer summed up the experience: “A standard alkaline is no match for these… brand new alkaline lasted less than 2 days, these keep going for months.”
Quick Verdict: Conditional — Worth it for high-drain or critical devices, overkill for low-drain use.
| Pros | Cons |
|---|---|
| Exceptionally long life in high-drain devices | Higher cost than alkaline |
| Performs in extreme cold/heat (-40°F to 140°F) | Not rechargeable |
| Leak-resistant design | Some reports of disappointing lifespan |
| Lightweight for portable gear | Counterfeit units in online marketplaces |
| Up to 20-25 year shelf life | Availability issues in some local stores |
| Works reliably in Nest Protect, Blink cams |
Claims vs Reality
Marketing promises “world’s longest lasting AA batteries” and “up to 9x longer life versus alkaline in digital cameras.” User experiences largely align — but not universally. Reddit user feedback on Best Buy’s Q&A confirms that lithium cells “last at least twice as long” in thermostats, while a reviewer using them in a video security camera reported “at least 10 mos to a year” before replacement.
However, Walmart’s customer md contested the longevity claim, saying these “did not last as long as their non-lithium counterparts… died very quickly” in small tools. This suggests that while in high-drain devices like DSLR cameras these batteries shine, low-drain or certain electronics may not see such large gains.
Another official spec is extreme temperature performance (-40°F to 140°F). Outdoor users back it up — Staples customer cold weather ready praised them as “excellent outdoor batteries… they last more than a year even with daily use” in security cameras and weather stations. In contrast, one game console user reported only “about 1 full day on an Xbox running nonstop” — showing performance depends heavily on device draw.
Cross-Platform Consensus
Universally Praised
Across Best Buy, Staples, and Trustpilot, the standout theme is unmatched battery life in critical devices. Blink doorbell camera owners say alkaline alternatives “die way too quickly” while Energizer lithiums work “in very cold or hot weather” and run for months. For photographers, Trustpilot reviews cite “several months” of power in Nikon cameras, while Reddit commenters confirm “much longer than regular batteries” for high-use gadgets like video scopes and smart thermostats.
Outdoor enthusiasts particularly benefit from the temperature resilience. A Reddit user noted that extreme temps don’t degrade function, making these cells ideal for mounted security systems or cold-weather camping lanterns. Amazon reviewers also point to their lightweight build as a plus for gear carried on long treks, supporting Energizer’s “1/3 lighter than alkaline” claim.
Common Complaints
The number one complaint is price. Best Buy reviewers repeatedly call them “a little pricey but worth the longevity,” while Walmart buyers label them “overpriced (everywhere).” Some small electronics users report lifespan not meeting expectations — marion on Walmart said “some didn’t last even two hours… must be defective,” indicating occasional quality variance or mismatch with device needs.
Another sore spot is counterfeit units on certain marketplaces. A Walmart customer bren 29 recounted receiving “fake Energizer batteries” packaged differently from official retail packs, advising caution when buying from third-party sellers. Notably, several Best Buy reviewers recommend avoiding Amazon for this specific product due to fakes.
Divisive Features
While leak resistance is heavily praised — “never leak like alkalines” according to Best Buy contributors — some Quora respondents warn lithiums are “a waste of money for solar lights” because they can’t recharge. Disposal requirements divide opinions too; eco-conscious buyers note they must be recycled, while others see that as an inconvenience.
Even longevity claims are divisive: outdoor camera owners affirm year-long runs, but Walmart’s md says their intended use cases didn’t see gains, underscoring that payback depends on matching battery chemistry to device load.
Trust & Reliability
Scam concerns emerged mainly from Walmart and Amazon marketplaces, with buyers detailing fake stock packaged incorrectly. Best Buy and Staples shoppers report fewer issues, reinforcing the community tip to buy from major retailers for authenticity.
Long-term durability gets glowing reviews from all sides. Best Buy customer using them in wireless mics found “a 4 pack of lithium AA’s outlast a 20 pack of alkaline” in identical conditions. Staples reviewers back multi-season reliability — deacon tim called them “lightweight and long lasting… ideal when weight is critical,” a sentiment echoed by Trustpilot users with over a year of usage in Blink cameras without loss of charge.
Alternatives
While direct competitors aren’t heavily discussed, Duracell alkalines are mentioned in passing — often as batteries tried before switching to Energizer lithiums due to short runtime. One Best Buy reviewer noted Nest Protect runtimes of “6+ months instead of ~1 month” after switching from Duracell and generic brands. Rechargeable NiMH cells appear only in technical Q&As, with users confirming lithium primaries are superior for extreme temps or long storage at the expense of reusability.
Price & Value
eBay listings peg an 8-pack around NZD 27–35, with expiration dates as far as 2048–2049. Staples sells them at $36.99 per 8-pack, while Walmart occasionally undercuts competitors. Community consensus is that while upfront cost is high, fewer replacements offset expense for high-drain gear.
Buying tips include Best Buy shoppers recommending brick-and-mortar purchase for authenticity and avoiding suspiciously cheap online listings. Bulk packs on eBay offer lower per-cell cost, but authenticity must be verified.
FAQ
Q: Can lithium AA batteries replace alkaline in all devices?
A: Yes in most cases, but check device compatibility. Reddit users note some gear relies on alkaline discharge behavior, though thermostats, cameras, and sensors generally work fine.
Q: Are these rechargeable?
A: No, they are single-use primaries. Best Buy Q&A warns “these are not rechargeable” and can’t be charged with NiMH chargers.
Q: How should they be disposed of?
A: Community guidance is to recycle through local centers; they should not be thrown in household trash.
Q: What is the mAh rating?
A: Quora contributors cite the datasheet listing ~1200 mAh to ~1.4V under load, but actual runtime varies by device draw.
Q: How long will they last in storage?
A: Official claim is 20–25 years, and users report no noticeable charge loss over several months to years when stored properly.
Final Verdict: Buy if you rely on high-drain or outdoor devices where longevity and temperature resilience matter — such as Blink cams, Nest Protect smoke detectors, or professional audio gear. Avoid if your devices are low-drain and replacement frequency is already low, as the cost may outweigh benefits. Pro tip from the community: purchase from trusted retailers like Best Buy or Staples to avoid counterfeit packs.
