Reliability when I need it the most
I use this in my scuba diving regulator for the durability and the reliability it gives me. The two pack was a great value for me because I always like to carry a spare. The power performance is superb and I know I can rely on Duracell.
These are great
I have a flash light that requires these type of batteries, as far as the longevity I give em a 7 out of 10, I use the flash light pretty often and have to change them out every couple of months
Duracell HP
I really like the Duracell HP batteries, they work really well. It also lasts a long time. I really recommend this product. Give it a try!!

Very good product, lasts long , can be used for multiple things at home. Powerful , durable , safe . One of the best among competitors.
This is a comment on a 1-star review
So, the person bought a "new" smoke detector with this battery in it and it didn't last very long. There is a LOT we don't know: (1) how old was this new smoke detector? The seller may have sold it cheaper because it had been sitting for a while. (2) was the house power ever off? in which case the battery would have taken over and drained. (3) Maybe there was a problem with the manufacturer or design of the smoke detector - we don't know (4) a high heat or humid environment [the detector is/should be ceiling mounted] can cause premature problems. The smoke detector buyer really should have pinged on the smoke detector manufacturer because it was their "system" of which the battery is only a part. Having said all this, there is such a thing as probability - of manufacturing error. Could have been the batter, but could have also been a part (resistor, capacitor, IC, etc.) in the smoke detector. The battery is a comparatively simple construction so I'd really be looking at the smoke detector. Having said all this, there is also such a thing as consumer error. Given the write-up, I'd take this persons "battery review" with a grain of salt.
longest lasting battery
Great battery for my kids high-drain devices. Works in Video Games and remote controlled cars.
Battery Expired after 3 months in smoke Detector
Included with my "First Alert" smoke detector 2 pack were new, Duracell Ultra CR2 batteries sealed separate from the detectors. Expiration date on the batteries are March 2021. I installed the smoke detectors after inserting the batteries 3 months ago. One of my detectors started to chirp last night indicating a "Low Charge Battery". ??? Being a Safety Device for the home, seems like it should have lasted a few years being it is included in a detector designed by a well known brand. Being a special size they have us over a barrel, charging a high price and poor performance.
