Duracell 2450 Lithium Coin Battery Review & Verdict
The Duracell 2450 3V Lithium Coin Battery (6 Count) has been called “reliable, long-lasting, and trustworthy” by thousands of buyers—earning an average rating of 4.7/5 across platforms. With its 10-year storage life guarantee and child-resistant packaging, Duracell’s marketing paints it as the premium choice for specialty devices. Digging into user reports, the praise largely holds up, but there are a few caution flags hidden in the feedback.
Quick Verdict: Conditional Buy
| Pros | Cons |
|---|---|
| Consistent long-lasting performance in glucometers, key fobs, remotes | Occasional reports of shorter battery life |
| 10-year storage guarantee holds true for most users | Higher price than generic brands |
| Child-resistant, tamper-proof packaging | Some find packaging overly difficult to open |
| Strong brand trust reputation | Unusual size limits availability in local stores |
| High energy density for demanding devices | Possible issues sourcing fresh stock online |
| Works in a wide temperature range | Not rechargeable – single-use only |
Claims vs Reality
Duracell advertises “reliable, long-lasting power” with up to a decade of shelf life. This is more than marketing fluff—many buyers confirm they’ve stored spare batteries for years with no degradation. A verified buyer on Amazon noted: "Pulled one from storage after 5 years, and it performed like the day I bought it." For medical device users, that shelf stability means no panicked trips to the store.
Duracell’s child-resistant packaging is another major claim. While the double blister pack offers safety, it can frustrate adult users. Reddit user feedback mirrors this, with one person admitting: "Had to fetch scissors and a fair bit of patience to get one out—no way a kid’s getting in." For households with small children, this inconvenience translates to peace of mind.
The brand also pushes its “#1 trusted battery” status. Trust is reflected in repeated customer decisions—one CVS Pharmacy reviewer wrote: "The battery was what my needs called for and I felt Duracell was a reputable brand name." However, reliability does come at a cost, with Duracell priced higher than generic CR2450 models, and that cost point splits opinions.
Cross-Platform Consensus
Universally Praised
Duracell’s consistency across demanding devices is the standout trait. For medical device users, this battery’s dependable voltage ensures accurate readings—a crucial factor for glucose meters and thermometers. A verified buyer praised: "Compatible with all sorts of electronics, and lasts long without erratic drops."
In automotive applications, from key fobs to tire pressure sensors, users enjoy the immediate startup capability even after sitting idle for months. This aligns with the spec sheet’s promise of “flat discharge voltage” and resilience to high altitudes—a feature noted by long-distance drivers.
Another group benefiting are owners of home security sensors and smart home devices. Several reviewers use Duracell 2450 cells in devices like door sensors, citing months of uninterrupted function. One Amazon buyer wrote: "Managed around 9 months on a smart lock sensor before the low-battery warning."
Common Complaints
While official specs note a capacity of 540 mAh, multiple reports flagged premature depletion under heavier loads. A summary from CellularNews highlights: "Some customers experienced shorter battery life," particularly in continuous drain devices. This makes the battery less appealing to high-drain wearables.
The child-proof packaging—though praised for safety—receives consistent complaints about difficulty. One buyer humorously noted: "It’s child-proof to the point of being almost adult-proof." Seniors or users with mobility issues often find it inconvenient.
Availability is another sore spot. Because CR2450 cells aren’t as ubiquitous as CR2032, some users had issues finding replacements locally, leading to reliance on online sellers where freshness can’t always be guaranteed. A few reported receiving “older stock” or what felt like partially depleted batteries.
Divisive Features
Price polarizes feedback. Fans of the brand see it as justified for peace of mind—especially for critical devices—while budget-conscious buyers argue performance isn’t vastly better than mid-tier competitors. The unusual size also makes “buying in bulk” less common unless there’s a specific use case.
While the 10-year shelf-life claim holds under ideal conditions, a handful of users in warmer climates doubt its longevity outside controlled storage. Reddit comments suggest storing them “inside, at stable temperatures” to match marketing claims.
Trust & Reliability
Duracell’s long-standing presence and manufacturing standards earn it trust, with Trustpilot-style feedback highlighting the brand’s reputation. The safety compliance—meeting UL and IEC standards—gets nods from those wary of cheap imports. There’s minimal concern about counterfeit product within official retail channels.
The battery’s long-term durability holds up in most accounts. Users returning months later frequently report steady voltage with little drop. A verified Amazon buyer explained: "Six months in my scale—still at full power." Failures, when they happen, tend to be linked to suspected old stock rather than manufacturing defects.
Alternatives
Competitors appear often in discussions:
- Panasonic CR2450: Slightly lower shelf life guarantee (8 years) but praised for wide temperature resilience. Some buyers cite possible genuineness issues in certain shipments.
- Energizer CR2450: Reliable fit for automotive remotes with competitive pricing, though some reviews mention requiring replacements as soon as a month.
- PG Sonic CR2450: Budget option with shorter shelf life (5 years) and occasional dead-on-arrival complaints, but high marks for leak-proof safety.
For users who value cost efficiency and can handle more frequent replacement cycles, Panasonic and PG Sonic offer viable trade-offs.
Price & Value
On eBay, single Duracell CR2450 cells list around $3.69–$7.49, with 6-packs more cost-efficient at roughly $15–$20. Amazon’s pricing aligns, but competitive bulk deals are rare for this size, reflecting niche demand.
Community advice emphasizes purchasing from trusted retailers to avoid old stock and counterfeit risks. Buying in packs allows consistent performance monitoring across multiple devices—useful for testers and technicians.
FAQ
Q: Is the Duracell 2450 compatible with CR2450 devices?
A: Yes. It’s fully interchangeable with DL2450 and CR2450 models, maintaining the same voltage and dimensions for cross-device compatibility.
Q: How long can it last in active use?
A: Lifespan varies by device load. In low-drain electronics like remotes, users see well over a year. High-drain sensors may only get several months.
Q: Can this battery be recharged?
A: No. It’s a single-use lithium coin cell. Attempting to recharge compromises safety and function.
Q: Is the child-resistant packaging easy to open?
A: It’s intentionally difficult to open without scissors, which protects children but can frustrate some adults.
Q: How should it be stored for maximum shelf life?
A: Keep in a cool, dry place away from direct sunlight. Staying within 10°C–25°C storage matches Duracell’s stated 10-year guarantee.
Final Verdict
Buy if you’re a medical device user, automotive owner, or smart home enthusiast who values accurate, reliable power over cost savings. Avoid if you need a battery for high-drain continuous use or if difficult packaging might pose accessibility issues.
Pro tip from community: Purchase from reputable sellers and avoid storing near heat sources to preserve the claimed 10-year shelf life.
