These desertcart 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. Review: Hard to beat these - I picked up these desertcart brand 9V batteries for everyday use, and they’ve honestly been a great value. I use them in things like smoke detectors, garage sensors, and a few handheld devices, and they’ve been reliable across the board. They come ready to go right out of the package, and I haven’t had any issues with weak or dead batteries like you sometimes get with cheaper brands. 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. If you need dependable 9V batteries without overspending, these are a smart buy. I’ll definitely keep these on hand. ## Features - IN THE BOX: 2-pack of 9-volt lithium batteries - DEVICE COMPATIBLE: Ideal for digital cameras, handheld games, smart home devices, outdoor surveillance systems, and more - DESIGNED TO LAST: retains power for up to 10 years in storage; store for later or use right away.

We use a lot of lithium 9 volt batteries at my company so I did capacity test. Unfortunately, my battery analyzer had an error and didn't complete the test. At the time of the error, the tested capacity was 942 mAh and the voltage was 7.49. The discharge setting was 0.25 amps. I may do another test in the future but since these are primary cells you have to waste a battery to do the test. **Q: Anybody know how these compare to Energizer brand? I've always had issues with off-brands not performing as well so I spend the extra $ on name brands** A: I've had these in place for 2 years now on digital door locks (barn and garage - no heat). Northern Michigan can get really cold in winter and standard battries have failed on a few occasions at very cold temps. So far these have not failed. As to longevity I can't give an experienced answer. **Q: What is the capacity rating (in mah) of the amazonbasics 9 volt lithium battery?** A: Amazon is keeping this a secret. But I can say they last longer in my devices then any other 9 volt battery I have used. I hope this helps. **Q: Does Amazon make dilithium batteries?** A: I don't know.
