Amazon Basics 8-Pack 9 Volt Lithium Batteries, 10-Year Shelf Life, Long Lasting Power

When it comes to 9V batteries, I’ve learned the hard way that you don’t want to go cheap, especially for items that protect your home. These Amazon Basics Lithium batteries are a fantastic middle ground. They offer the long-term reliability of lithium at a price that doesn't feel like a luxury purchase. I swapped these into all my smoke and CO2 detectors, and having that 10-year shelf life provides some serious peace of mind. They maintain a consistent voltage and don't seem to suffer from the "leakage" issues you find with cheaper alkaline brands. Whether you're using them for household safety or for high-drain electronics like guitar pedals or wireless mics, they hold up under pressure. It’s a boring purchase, but a necessary one, and these get the job done right. Pros: • Long Shelf Life: 10-year rating means you can stock up without worrying about them going dead in the drawer. • Lithium Performance: Much more consistent power delivery and temperature resistance than alkaline. • Great Value: Performance is on par with the "name brands" for a fraction of the cost. • Leak Resistant: Solid construction reduces the risk of ruining expensive electronics. Cons: • Initial Cost: More expensive than standard alkaline, but you save money in the long run by changing them less often. • Disposal: Like all lithium batteries, you need to dispose of them properly at a recycling center. Verdict: This is a 5-star essential. If you’re tired of the "low battery" chirp in the middle of the night, upgrade to these. They are reliable, long-lasting, and a smart investment for home maintenance.

The lifespan has been solid too—no constant swapping them out, which is exactly what you want, especially for devices you don’t check often. For the price, these are hard to beat. They may not have the name recognition of premium brands, but performance-wise they’ve held their own in my experience.

Not bad, Not great, Serviceable.

Purchase these so I didn’t have to replace all of my smoke detector batteries so frequently. So far it’s working well. It’s a great value for the money, convenience, and quality.

Long shelf life. Easy storage.

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.

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.

Pretty good value for a lithium battery. Now to see how well it lasts!

Good

No me sirvió

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.

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.
