CR2 Non-Rechargeabe Battery

I'm very impressed with the funkawa (2-Pack) CR2 3 Volt Lithium Batteries. They offer high capacity, durability, and compatibility with a variety of devices. If you're looking for reliable lithium batteries that provide great value for money, these are an excellent choice. I highly recommend them for their performance, versatility, and long-lasting power. You won't be disappointed with this purchase!

The battery fits a Nest remote sensor just fine. When I first installed the battery, the sensor kept giving a warning that the signal strength to the main thermostat was weak. This went away by itself after a few days, I'm not sure why a new battery would cause this. Other than that, there is nothing else to report. We'll see how long it lasts. The one that came with the sensor lasted several years, I hope this one will too!

They replaced the existing battery and worked flawlessly.

The package was a bit small, but I get it. Cost savings. I only needed it to operate an old film camera with film in and a dead battery, and I wasn't paying $20 USD for two over the counter. I will probably resell them as I have no further need for them now.

Used for range finder. Good!

I was very skeptical about buying these batteries. Other brands are much more expensive, include less batteries, and have a lower mAh time. I thought these were too good to be true but I was shocked with how great these batteries are. They charge very quickly with a 30 minute charge time on a dead cell from my soshine cr2 charger. The charge lasts quite a long time. I didn’t know they came with a case either so that’s a huge bonus. Overall very happy customer. I would like to see more of what Shockli has to offer in the future. 10/10

More mah than other batteries of the same size

Works as descripted. Worth the investment!!!
