9V Lithium Batteries, 1200mAh Lithium 9 Volt Batteries, 10 Year Shelf Life, Long-Lasting Power for Smoke Detector, Microphone and Walkie Talkie, Non-Rechargeable 4 Pack

I’ve been using these Batteriol 9V lithium batteries in smoke detectors, wireless microphones, and a few other low-drain devices around the house. The 1200mAh capacity gives noticeably longer runtime than standard alkaline 9V batteries, and the 10-year shelf life is a big plus for emergency kits. They hold voltage well and don’t leak like some cheaper options. They work reliably and the performance is solid for the price. The only downside is that they’re a bit more expensive per battery than basic alkalines, and I didn’t notice a huge difference in high-drain devices compared to name-brand lithiums. Overall, a good choice if you want reliable 9V power with minimal maintenance and long storage life.

I used these on my outdoor garage door key pads and they work fine. I had trouble in the past on cold days with standard 9 v batteries. These work even in the coldest weather.

Easy replacement of standard 9 volt Great for extending the time between changes for smoke detectors

Worked perfectly right out of the plastic wrap. An honest review can’t be given just because I it hasn’t been years since I installed them. The only reason I’m giving it four stars instead of five is because I also bought the Amazon variety and they had the package of 4 mounted so beautifully + extra safe.

Perfect for smoke detectors to not have to change every year

Arrived nicely packed, and you won't find lithium 9-volt batteries at a better price!

Have in a radio car use for 60 days usually turn on in the morning for 15/20 minutes and ran down in 60 days so not real happy with performance. But they supposed don’t leak being there lithium.

These batteries have a very long shelf life. They are good for "keep-alive" in clocks, clock radios, and smoke-alarms.
