I purchased a 2-pack 9V Duracell (with duralock) to replace a battery in a smoke detector approximately 2 months ago. These smoke detectors are also hard-wired so the battery is merely a "back-up". The thing is chirping already! I put the second battery from the pack in and it starting chirping almost immediately. Just went to the store and purchased an Energizer 9V which seems to have fixed the issue. I really expect about a year of use out of these 9V batteries in the smoke detectors...not 2 months.
Does Duracell actually back the 10 year guarantee?

These batteries are not that leak proof. I heard the ones in my TV remote bubbling last night and I opened the battery compartment to find a clear liquid coming out of the battery. I went to replace the batteries and found most of the ones left in the package had already bulged and crystallized. The expiry date for these batteries are supposed to be 2023 and they were stored at room temperature inside a living room. Does Duracell actually back their 10 year guarantee? I've had Duracell batteries leak before, but I thought these new ones would fair better.
I used to believe their commercials, it was worth to pay premium for batteries that can work in harsh environments, that had to work when you need them most (that flashlight in your car when you are stranded in the middle of nowhere). The ones emergency personnel trust. Etc. Just found my 2 AA Maglite with 2 corroded batteries I can not even remove, then checked, and found: LED lamp with 4 AA corroded batteries Photography Flash unit with 4AA corroded batteries My spare car pack (4AA) 2 corroded. Sharp Home stereo remote 2AA corroded
I can't tell you how many of my items have been victim to leaking Duracell batteries over the past two years. They used to be good but something has changed, I think I will change brands also, sick of this constant problem.
