Energizer CR2025 Batteries Review: Conditional Verdict 7.8/10
Starting at nearly 80% positive reviews but facing a surprising number of reliability concerns, the Energizer CR2025 Batteries (6 Count) earn a conditional score of 7.8/10. While marketed for their 10-year shelf life and dependable performance, user experiences reveal a split between buyers who get long-lasting cells and those struggling with rapid drain or suspected counterfeit stock.
Quick Verdict: Conditional — Strong performance if genuine and fresh, but packaging issues and short life complaints require caution.
| Pros | Cons |
|---|---|
| Holds power for years in storage (when fresh) | Reports of batteries dying within days or weeks |
| Compatible with wide range of devices | No expiration date printed on some packages |
| Performs in extreme temperatures | Multiple buyers received fewer batteries than ordered |
| Affordable compared to in-store prices | Counterfeit concerns due to inconsistent branding |
| Leak-resistant under normal use | Poor packaging quality; thin foil tears easily |
Claims vs Reality
One of Energizer’s key promises is a 10-year storage life for these CR2025 lithium coin cells. The marketing states they can operate in temperatures from -22°F to 140°F with reliable output for heart rate monitors, key fobs, glucose meters, and other specialty devices. However, while Amazon specs and Energizer’s own product pages highlight that durability, some verified buyers say their new batteries drained almost immediately.
A verified buyer on Amazon noted: “Within 15 hours my Fitbit was reporting low battery” despite being advertised as long-life cells. This gap between claim and reality is especially problematic for users needing consistent performance in medical devices where failure can be more than an inconvenience.
Another claim is extreme temperature performance. While Energizer promises stability in cold and heat, Reddit reviewers focus more on real-world use in small electronics. One reviewer from Bestviewsreviews cited: “3 volts charge gives long-lasting performance in devices like heart monitors, remotes, etc.” — but this praise is undermined by other reports of premature failures even in normal indoor conditions.
Cross-Platform Consensus
Universally Praised
Buyers across Amazon, Reddit, and eBay appreciate the compatibility range. These batteries fit devices from Swatch, Fossil, Timex, and Casio watches to automotive key fobs and glucose monitors. A Reddit user highlighted their convenience: “Perfect for Mercedes owners who don’t want to spend $8 for the same battery from Mercedes.” For budget-conscious users, bulk packs on eBay and online retailers mean avoiding frequent store trips. Users also trust the leak resistance; batteryproducts.com promotes them as “100% leakproof in standard use,” a reassurance for those leaving cells installed for months at a time.
Durability under proper conditions does get some solid endorsements. Several verified Amazon buyers found them “quality batteries for a fair price” and praised that “batteries work very good,” especially when used in low-drain devices. This reliability makes them attractive to hobbyists, watch collectors, and those stocking emergency kits.
Common Complaints
Reliability issues dominate negative feedback. On Trustpilot and Amazon, some consumers allege receiving “counterfeit crap” or cells that “measure fine open circuit, but voltage drops quickly under even a light load.” Others suspect expired stock due to absent date codes. Reports of batteries dying within a week or two — far short of the advertised months of life — are common, especially from Fitbit and Orbit app users.
Packaging flaws add frustration. The thin foil backing can tear easily, exposing or even dislodging other cells. Some reviewers received fewer batteries than ordered — “only 2 batteries out of 4” or “single battery received when ordered a card of 5.” This leads to speculation about poor seller quality control or repackaging of returned stock. Delivery was sometimes slow, undermining the “fast shipping” many others praise.
Divisive Features
Bulk pricing divides opinion. While some celebrate the low cost — “the pack of 5 was about the same price as 1 at local stores” — others believe the savings are meaningless if the cells fail early or arrive incomplete. The wide temperature tolerance is another mixed point; outdoor enthusiasts value it for cold-weather trips, but for indoor electronics users, the real-life advantage is minimal compared to simply getting fresh stock that lasts.
Trust & Reliability
Trustpilot patterns suggest intermittent counterfeit or misrepresented batches. One flagged review described mismatched fonts compared to genuine Energizer products and battery tests revealing poor load capacity. Another buyer warned: “Stay away. Batteries dead right out the package. Waste of money.” This is reinforced by Amazon complaint threads about missing expiration dates.
On Reddit, longer-term updates show stark contrasts: some say they’re “still using the same battery six months later,” while others swapped out multiple cells in under two weeks. The absence of date codes makes tracking stock age impossible, which for some buyers is a deal-breaker.
Alternatives
Competitors mentioned by reviewers include Panasonic CR2025 and Amazon Basics coin cells. Panasonic earns praise for “extremely high energy density” and compliance with strict safety standards, making it appealing for medical and safety devices. Amazon Basics offers child-resistant packaging and zero mercury, good for family environments, but scored lower at 7.7 vs. Energizer’s higher marks when genuine and fresh. Buyers seeking certainty on freshness may prefer Panasonic’s clearly dated packaging even if it costs more.
Price & Value
On eBay, genuine fresh Energizer CR2025 cells expiring in 2031 are listed around $2.34 for 2 pieces, with larger lots dropping below $0.80 per cell. This undercuts retail drugstore pricing, which some Amazon reviewers say can exceed $4 per battery. However, buying from unknown sellers increases the risk of expired or counterfeit stock. Several buyers explicitly recommend purchasing from reputable high-turnover sources like recognized electronics or camera shops.
FAQ
Q: Do these Energizer CR2025 batteries actually last 10 years in storage?
A: When genuine and properly stored, yes — multiple users confirm long shelf life. However, absence of printed expiration dates in some packs makes verifying age difficult.
Q: Are these batteries safe for high-drain devices?
A: They work well for moderate drain devices like remotes and watches. Some users report rapid drain in trackers like Fitbit, suggesting they may be better suited for lower-drain electronics.
Q: How can I avoid counterfeit CR2025 cells?
A: Buy from verified sellers with recent manufacturing dates. Check packaging quality and font consistency against official Energizer samples.
Q: Why did I receive fewer batteries than ordered?
A: Multiple buyers suspect poor seller handling or repackaging errors. Reputable retailers are less likely to have quantity mismatches.
Q: Will they leak if left inside a device?
A: Under standard use, reports confirm they are leakproof — even after months installed. Energizer advertises 100% leak resistance in normal conditions.
Final Verdict: Buy if you need a versatile, broadly compatible coin cell and can source from trusted sellers who guarantee recent production. Avoid if you require absolute certainty on long-term reliability, especially for crucial medical devices. Pro tip from community: Pay a little more at a reputable store to ensure fresh stock — the small extra cost can save you from weeks of frustration and multiple replacements.
