4-Pack CR2 Lithium Batteries, 3 Volt, Long Lasting Power, Reliable, Low Self-Discharge Rate

I bought these Amazon Basics CR2 Lithium Batteries to use in a Google sensor, and they’ve worked perfectly so far. Installation was straightforward, and the sensor powered on immediately without any issues. The batteries deliver consistent performance, and I haven’t experienced any dropouts or low-battery warnings since installing them. One thing I like is the low self-discharge rate, which is especially important for sensors that are always on but don’t draw much power. They seem well-suited for smart home devices where reliability matters more than high drain output. The batteries also feel well-made and comparable to more expensive name-brand options. For the price, this 4-pack is a great value. If you need CR2 batteries for Google sensors or other similar devices, these are a reliable and cost-effective choice. I would definitely buy them again.

I’ve been using the Amazon Basics CR2 Lithium Batteries for a variety of devices—my digital camera, flashlight, and even a golf rangefinder—and they’ve proven to be an outstanding choice. For an affordable pack of four, these 3-volt lithium batteries deliver impressive performance that rivals more expensive brands. I’m genuinely thrilled with how well they hold up, and they’ve quickly become my go-to option for CR2-powered gadgets. Pros: • Long-Lasting Power: These batteries have a low self-discharge rate, meaning they stay fresh for years when stored. I’ve used them in high-drain devices, and they last impressively long—weeks of frequent use in my camera without a hitch! • Versatile Performance: They work flawlessly in both high and low temperatures, making them perfect for outdoor gear like flashlights or sensors. I’ve had no issues even in chilly weather. • Great Value: At this price point, you’re getting four reliable batteries that compete with premium brands. It’s hard to beat the cost-to-performance ratio. • Consistent Reliability: Every battery in the pack has delivered steady power with no duds. They fit perfectly in all my CR2-compatible devices and keep them running smoothly. • Compact and Lightweight: Easy to carry spares in a bag or pocket without adding bulk, which is a huge plus for on-the-go use. Cons: • Not Rechargeable: These are single-use batteries, so if you’re looking for a rechargeable option, you’ll need to look elsewhere (though Amazon Basics does offer rechargeable alternatives separately). • Packaging Could Be Improved: The pack comes in basic plastic that’s a bit tricky to open without scissors. A resealable design would be more convenient for storing unused batteries. In short, the Amazon Basics CR2 Lithium Batteries are a fantastic buy—reliable, long-lasting, and budget-friendly. They’ve powered my devices without fail, and I love knowing I’ve got dependable spares ready when I need them. If you need CR2 batteries that won’t let you down, this pack deserves a solid five stars!

I bought this to replace the battery in a security camera. The original battery lasted more than five years, so hoping for the same kind of longevity with this. It's been installed for a year now, and no warning about the battery running low, so I suspect it is good. Price is excellent, and these are hard to source locally. It was an exact fit in the camera and easy to install.

Dependable, Long-Lasting CR2 Batteries at a Fair Price The Amazon Basics CR2 Lithium Batteries deliver the kind of steady, reliable power I’ve come to expect from the brand. I’ve used them in everything from my golf rangefinder to an older digital camera and motion sensor lights, and they’ve held up well. Each cell feels solidly built, with consistent voltage out of the package and no leaks or weak units. Performance-wise, they last just as long as big-name competitors like Energizer or Duracell in typical use. They handle cold mornings on the course and warm outdoor conditions without a noticeable drop in performance, which is a plus if you’re using them for outdoor gear or smart home devices. The low self-discharge rate also means they stay fresh for years in storage—handy for backup stock. My only small gripe is the packaging—it’s simple but not resealable, so you’ll want a small container to keep the spares together. And of course, they’re not rechargeable, which might matter if you use CR2 devices frequently. Still, for most people needing a reliable, affordable CR2 battery for cameras, rangefinders, or sensors, these are tough to beat. Bottom line: Consistent, long-lasting, and dependable CR2 batteries that perform as well as premium brands for a fraction of the price.

These Amazon Basics CR2 lithium batteries pack a serious punch. Long-lasting power? Check. Reliable performance? Double check. Basically, they keep going so long I sometimes forget what “low battery” even means anymore. If you need batteries for your gadgets that don’t die faster than your phone battery on a Netflix binge, these are your new best friends. Sure, they don’t sparkle or sing, but hey, they keep your devices alive—and isn’t that the real magic?

There batteries they do what they need to weight a normal battery weight and have a normal battery capacity I think they are the exact same as like Duracell batteries. Good value for money cause cheaper the Duracell.

Great batteries at a Great price

Works great in the Nest Thermostat plug in.

Works as expected

Works best with instax sq 6 if anyone’s wondering

Ich habe diese Batterien für meine SwitchBots gekauft, da dort dieser spezielle Typ benötigt wird. Das ist ein für mich spezielleres Format, das man so nicht überall bekommt. Passform: Die Batterien entsprechen exakt der CR2-Norm und lassen sich problemlos in die vorgesehenen Batteriefächer einsetzen. Leistung: Bisher verhalten sich die Batterien unauffällig und liefern die benötigte Energie stabil, wie das mitgelieferte Original. Zur langfristigen Haltbarkeit lässt sich nach kurzer Zeit noch nichts sagen, aber der erste Eindruck ist gut. Preis-Leistung: Wie für Amazon Basics typisch, ist der Preis absolut in Ordnung und deutlich attraktiver als bei vielen Markenherstellern im Einzelhandel, sofern man die da findet. Fazit: Eine preiswerte und funktionale Lösung für alle, die spezielle Batterietypen für ihre Smart-Home-Hardware benötigen.

スイッチボット用に購入！ お安くてしっかりと用をなす。これが当たり前だけど大切。 ただし、コストコやAmazonの乾電池は、長期保管時の質の低下がネック。 かったばかりなので、保管期間中の放電液漏れなどは追加予定。

Très bien
