Review: Bought two 8-packs of these, they fit my Kidde smoke detectors and measured 9.5 V on arrival. - I have a lot of smoke detectors in my house. One of them began chirping a few days back, reminding me it's time to refresh them all with fresh 9V backup batteries. So I bought two 8-packs of these Rayovac "Ultra Pros." I ordered them in early July, 2019, and each of the batteries I received were individually labeled "Feb 2023" so it's unlikely that these had been sitting for a long time in a warehouse losing charge. When I replace batteries in my smoke detectors, I always test the voltage of the new battery I'm about to put in to make sure it's working and reasonably fresh. I only needed 12 of the 16 batteries for my detectors but went ahead and tested all 16 of these for the heck of it. They would initially read 9.39 V or 9.40 V, but if I held the testing leads to them for another 30 seconds the reading would slowly climb up to 9.50 V. I've seen other alkaline 9V batteries that measure 9.55 V or slightly higher when fresh, but I was satisfied that these all reached 9.50 and that there were no duds among my order. Note that every year or two my homeowner's insurance mails me some 9V batteries bearing their own logo, and those ones seem to have about a 20% dud rate, no joke -- this is why I decided to buy name-brand ones for my smoke detectors as I need them to work and to last a decent length of time. It's also why I decided not to buy the desertcartBasics 9V batteries. I've had great luck with desertcartBasics AA and AAA rechargeables but the reviews of the desertcartBasics 9V alkalines left me with the impression that the quality control isn't all there. Enough said -- these seemed reasonably priced, fit my Kidde-brand smoke detectors, and based on the initial voltage readings they are fresh batteries that I hope to get 16 to 18 months out of before needing to replace them.
Review: Smoke detectors worked well - I realize they say to replace smoke detector batteries yearly but man they got expensive. Anyway. Bought these in 2022 and changed them out today. No issues in 4 smoke detectors for 2 years that are hardwired and battery is backup. I would say worth it compared to big box stores charging just about double.

### ⭐⭐⭐⭐⭐ Smoke detectors worked well
*by L***N on October 30, 2024*

No issues in 4 smoke detectors for 2 years that are hardwired and battery is backup. I would say worth it compared to big box stores charging just about double.

### ⭐⭐⭐⭐⭐ Yes--very good choice for smoke alarms/CO detectors
*by R***H on November 3, 2019*

I've been using these 6 pack Rayovac 9V for a few years now primarily in smoke detectors in multiple properties (hardwired with battery backup type). I've used in both BRK and Kidde/Firex brands--these batteries fit fine. I tried using the ~$9 each Lithium batteries made by Energizer? as they listed 10 year life--no way you will get 10 years--more like 4 years in a hardwired battery backup smoke alarm. I've tried alkaline Energizer, Duracell, and these Rayovac--I don't see any difference in longevity when used in smoke detectors. PS: smoke detector companies now make smoke detectors with built in/non replaceable 10 year battery--a bit more expensive (around $55 for hardwired versions from what I recall) which I have started using--yes, a bit pricey but if it eliminates one call for "it's chirping" from an aging relative at 3am scared its carbon monoxide or just can't sleep it is well worth it--time will tell how long these "10 year built in battery" smoke detectors actually last.
