Duracell CR2025 Battery Review: Long-Lasting & Safe
The surprising part about the Duracell Lithium Battery CR2025 is how consistently it delivers on its longevity claims across different types of devices — something rarely matched in the button-cell category. With an aggregated score hovering around 9/10 from thousands of reviews, users widely describe it as a dependable, safety-focused coin cell that justifies its price premium. The combination of high-purity lithium chemistry, a bitter-coating child safety feature, and a 10-year storage guarantee has earned it trust among both casual and critical buyers.

Claims vs Reality
Duracell markets the CR2025 as providing “long-lasting power” with “up to 70% extra life” compared to the IEC standard minimum for similar cells. While such metrics can be abstract, user experiences consistently align with these claims. A verified buyer on Amazon noted: "Used these for my key fob and backup. Other brands with high review count died within a short period. These however are durable." This feedback mirrors dozens of similar reports, particularly from those using them in key fobs and glucometers, where consistent output is critical.
Another prominent claim is the “bitter taste coating” designed to discourage accidental ingestion by children. Multiple sources confirm this is unique among major brands. According to the Duracell Singapore product page, "when in contact with saliva, it's identified as a potential toxic by the brain, prompting the child to spit the battery out." While no user explicitly reported a child ingestion incident, parents in forums expressed peace of mind knowing the feature exists.
Duracell also emphasizes its “child-secure packaging” that is “nearly impossible to open without scissors.” Here, reality matches — sometimes too well. Reddit discussions and Amazon reviews include comments like: "Packaging is ridiculously tough to open — which is good for safety, but frustrating if you don't have scissors handy."
Cross-Platform Consensus
Universally Praised
Across Amazon, Reddit, and Trustpilot, the CR2025’s longevity is the top praise point. A Trustpilot reviewer shared: "Bought for my Mazda CX5 key — still going strong after a year." For medical device users, this reliability is more than convenience; it’s about avoiding sudden power loss. One Amazon buyer using it in a wall AC remote wrote, "They fit well and worked without any issue," adding that replacements are infrequent.
The broad compatibility also resonates. Devices listed range from remote controls and watches to heart rate monitors and bicycle accessories. A Dutch-language review on UNU.ai emphasized how they "fit perfectly in most devices that need a coin cell battery… no need to stock multiple types." This is particularly valued by families who keep spares for various gadgets.
Finally, shelf life earns consistent praise. Users like the idea of buying a multi-pack and storing them for years without degradation. The 10-year storage claim is repeatedly cited in purchasing decisions, especially by those who keep emergency kits.
Common Complaints
The packaging difficulty is a double-edged sword. While the child-proof aspect is lauded for safety, adults — especially seniors — sometimes struggle. One CVS customer remarked: "Just the right size battery… but had to wrestle with the packaging." This is more than a minor annoyance for those with limited hand strength.
Counterfeit risk appears in community warnings, particularly when ordering from third-party marketplace sellers. While the majority of buyers receive genuine batteries, a few note shorter-than-expected lifespans and suspect authenticity.
Price is the other recurring complaint. eBay listings show cheaper alternatives at less than half the cost, but many users stick with Duracell for peace of mind. As one Amazon reviewer bluntly put it: "Worth the $, good value" — suggesting some see the higher price as justified insurance against poor performance.
Divisive Features
The bitter coating is polarizing. Parents of young children appreciate it, but some buyers without kids view it as irrelevant, even questioning if it adds unnecessary cost. Similarly, while some praise the double blister packaging as essential, others see it as environmentally wasteful and excessive.
Trust & Reliability
Trustpilot and Amazon reviews largely reflect confidence in the brand’s authenticity and performance. Many users cite years of trouble-free use. One Trustpilot review noted: "Other brands with high review count died within a short period. These however are durable." The consistency of performance over months or years reinforces brand loyalty.
However, counterfeit concerns persist. Seasoned buyers recommend purchasing only from official retailers or verified sellers to avoid short-lived knockoffs. This advice is echoed across Reddit and eBay discussions, where reports of suspicious packaging or early failures often correlate with unverified sellers.
Alternatives
While direct competitors aren’t heavily discussed in the provided data, users implicitly compare Duracell to generic coin cells and brands like Energizer. The consensus is that while generics can be cheaper, they often require more frequent replacements. Energizer is sometimes mentioned as a comparable alternative, but Duracell’s unique child safety features are seen as a differentiator.
Price & Value
Current eBay listings show two-packs priced from £1.49 to £4.29, with bulk packs offering better per-unit rates. The Amazon US price hovers around $6.30 for a two-pack, reflecting a premium over generics. Community advice leans toward buying multi-packs during sales to maximize value, especially given the long shelf life.
A verified buyer on Amazon captured the sentiment: "Quick delivery at a great price… worth the wait." For those needing reliable performance in critical devices, most agree the cost is offset by reduced replacement frequency.
