Good for the money

Needed for a small safe, standard battery doesn't last long, 3 to four months or so I thought I would try them out. Will update on new timeline of these new batteries.

The product itself works just fine. Stars were removed because they shipped batteries that are over 18 months old!

They were all separated perfectly in the same box of four equal distance apart, so they would not touch or discharge prematurely. Super safe and very well done! Presentation presentation presentation! I will see how they last and perform overtime. I bought a different variety also and placed in the service at the same time, so we will see which one lasts the longest!

These have worked as well as the Energizer so far, and no leaks (as expected for lithium), and much cheaper. They are closer to normal shape (a little rounded) than Energizer, so actually fit in more things *but* still not as rounded on the edges as regular alkaline, so I have found a couple things they won't fit in (see photo...a regular one is quite rounded on corners, and En3rgizer are sharp corners)

Batteries came well packed with each in its own slot and individually shrink wrapped. I checked the voltage with a VOM and 10 were at 9.68 v and 2 were at 9.67 v. The dates on all were 06 2035 which is 9 years and 8 months out from delivery date of 10/1/25. The form factor is identical to a name brand alkaline 9v it had. Fits my First Alert smoke detector just like name brand (snug). For all intents and purposes, these appear to be just as good as a name brand for a lot less. If the long term discharge remains low, then these are winners. Will try to remember to update this review after a few years.

Great batteries at a great price

I got two of these batteries for the electronic combination lock on a safe. Now, to remove and replace the batteries in the lock mechanism is a real pain in the neck, so you don't want to do it often. Lithium batteries last a lot longer than alkaline batteries; also, these batteries have been found to put out a true 9-volts, not 8.5 like the Everyready Energizer 9-volts. Lithium batteries are lighter than alkalines and withstand extreme cold much better. There is one caveat: when lithium batteries go, they go with no warning, unlike the noticeable decrease in performance in an alkaline battery. So replace lithium batteries on a schedule. I will leave the lithium batteries in my safe for 5 years; I will replace them after that. These should power devices like a smoke detector for 3 - 4 years--but don't wait for a low-battery indicator, because you might not get one. Lithiums provide full power until the end of their life, unlike alkalines, which will slowly decrease in performance. So if you use these in a smoke detector, replace at a set interval. You won't have to replace lithiums in a smoke detector every year. So, if you have a smoke detector in an out-of-the-way place, lithiums are a good choice. I would change the lithiums every four years in a smoke detector; it's just not worth it to "push your luck" for such a device. If the batteries die in my electronic combination lock, no problem--I just have to replace them. Just make sure you have a fixed schedule for replacing the lithium batteries in any device--and you'll save a lot of hassle changing batteries frequently.

I tried an Energizer lithium 9 volt in my Liftmaster garage door keypad and it would not fit as it is slightly larger than their regular 9 volt batteries. This Amazon Basic 9 volt lithium is a normal 9 volt size and works great in the cold weather. It says it is good to minus 40 Celsius. My regular 9 volts stopped working on the Liftmaster at minus 20-25 Celsius.

No me sirvió

Batteries are great non leak saves my equipment.

I own far too many musical instruments (ask my wife!) — at last count, seven basses, two guitars, and a mandolin. All except the mandolin require a 9V battery and, because I live in mortal fear of having power go out on me half-way through a gig (it's happened), I opt for lithium-ion batteries for consistent power and longevity. The only problem is that Li-ions are expensive — I've seen them for as much as $15-99 for a single 9V in the stores. And then I spotted this set of eight on Amazon for around $5 a battery — given Amazon's decent reputation, I had no hesitation in ordering. On delivery, I tested a couple of them with a multi-meter, and they both measured around 9.8V — excellent! I've just ordered a second set of eight.
