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

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 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.

Good brand, i use these in various security alarm sensors. Amazon Basics always has a lower cost per unit than others. The battery has never leaked and lasts at least 6 months in the sensors.

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 work for fire alarms and don't chirp early. My main requirement is that they are not trash and live long, and for that they serve the purpose perfectly.

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.

Good battery for range finder. Had on shelf for year or so before using them all and they seemed to have good battery life and performance in cold conditions

I use the CR2 for my EDC flashlight. The batteries seem expensive when purchased individually. This bulk pack increases the value/price point and the quality is shown by the equal life/power span to the name brand batteries.

Works as expected

These batteries are hard to find and I am very happy with these ones I got from Amazon. These batiereis are used in our security system and we change them once a year and then the old ones are used in my husbands golf gps until they are completely dead. We have never had a battery die before they where scheduled to be changed and it is great when you have another device that can use the same batteries until all the charge is gone.

Rapport qualité/prix bien

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。
