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

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 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.

worked well, good batteries. Good value.

I received one of batteries was not working , I am not sure why , but worth the price

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.

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!

Nothing fancy here, but they work exactly as expected. Good power, no issues with leakage or short life. Sometimes simple and reliable is all you need.

Another great battery from Amazon. No issues. They seem to work great.

Bought it for my old camera. The batteries are great but my camera is dead.

Works as expected

Works best with instax sq 6 if anyone’s wondering

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
