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

So far so good. Range finder replacement batteries. The 4 pack allows me to keep a spare with the unit and a battery in each pack I might use. Hard to know how long it will last, especially compared to your big names, but considering the difference in price, who cares; I'll be able to afford to buy more.

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!

These batteries last pretty long for my door/motion sensor. Can't beat the price compare to the big brand.

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.

Not much to say here that isn't obvious, these are batteries, and they work. I picked these up specifically for Google Nest Temperature Sensors, which require the less common CR2 size that you won't find at every local store. Amazon Basics delivers the right chemistry at a fraction of the name brand price. No leaking, no connectivity issues with the sensors, and the 4-pack gives you enough to stock the sensors plus keep a spare or two on hand. For a specialty battery size, the value is hard to beat. Bottom line: Reliable, affordable, and exactly what Nest sensor owners need. Skip the name brand markup, get these!!

Works great in smoke alarm

What is for my rangefinder and it works.

I haven’t done any official testing but it seems like these last a little shorter then name brands but they so much cheaper who really cares. Solid product, great price, lasts long enough I won’t pay for the name brand.

Works as expected

Good quality battery. Last a long time. Better than some cheaper brands I’ve bought in the past.

The battery is fine only problem is I don't need 4at a time

Works best with instax sq 6 if anyone’s wondering

Un vrai basique à avoir à la maison ! 🔋 J’ai acheté ce lot il y a déjà plusieurs années et j’en utilise encore aujourd’hui. Les piles tiennent vraiment bien dans le temps et je n’ai eu aucun souci avec celles que j’ai utilisées jusqu’à présent. J’apprécie particulièrement le format CR2, qui n’est pas toujours facile à trouver en magasin. Avoir un lot de 12 permet donc d’avoir toujours quelques piles d’avance lorsqu’on en a besoin, plutôt que de devoir courir en acheter une au dernier moment. Après plusieurs années, je trouve que la qualité est vraiment au rendez-vous. Pour moi, c’est typiquement le genre de produit basique mais indispensable qu’il vaut mieux avoir dans un tiroir surtout avec des enfants ! 👍🔋
