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: Great Batteries At A Great Price! - I try to use Rayovac batteries in my 6 smoke detectors if I can get them. I did use one of the other name brands but started to have some problems with them going dead before the year of smoke detector use was up. Since I started to use Rayovac....for the past 5 years, that has not happened. I don't have to worry about these going dead. As a matter of fact, they still have a lot of juice left in them at the end of the year, so I save them for my grandchildren to use in their controllers and such! Great Batteries At A Great Price!
