POWEROWL CR2 3V Lithium Battery, 6 Pack High Capacity CR15h270 CR 2 C2 3 Volt Batteries Cell, Long Lasting Power

These CR2 batteries have been perfect for keeping all the smoke alarms in our house powered and working properly. It's such a relief to have a 6-pack on hand so I'm not scrambling to find the right battery size every time one starts chirping — I just grab a fresh one from the pack and I'm done. They've held a strong charge so far and installation was simple, straightforward drop-in with no issues. Knowing our smoke detectors are reliably powered gives real peace of mind, especially with multiple alarms throughout the house to maintain. Great price for the quantity compared to buying CR2 batteries individually elsewhere, and having extras on hand means I can also use them for other devices that take this size (cameras, flashlights, etc.). Will definitely be repurchasing when we run low — highly recommend for anyone who needs a reliable stock of CR2 batteries at home.

Good price... work well...

bought this for a range finder, and it works GREAT, with tons to spare. Better price than the name brands out there, and these are perfect

Work perfectly on my rifle optic. Suitable for every day use, and reliable. Good value and decent battery life so far.

I’ve been using this setup with my Level Lock, and it’s worked out really well for me. These batteries hold up great—I'm consistently getting several months of use before I ever have to swap them out. The lock runs smooth, responds quickly, and I’ve never had any unexpected low-battery issues. For something you rely on every day, that kind of reliability really matters. Overall, the combination works perfectly in my home. If you’re looking for dependable batteries that keep your Level Lock running strong, this has been a great choice in my experience.

It offers excellent value for money, boasts meticulous craftsmanship, and delivers powerful performance.

Honestly, they just make life easier. Highly recommended.
