Enegitech 9V Lithium Battery, 9 Volt Lithium Battery 1200mAh for Smoke Detector, Fire Alarm, Keyless Entry Door Lock, Multimeter, Metal Detector Non-Rechargeable 4 Pack

These batteries are great! We use them for the bass guitar at church. They last longer than any other brand we've tried, and we've tried a lot of them. I've subscribed so that we will never run out!

These are standard Li-ion batteries useful for smoke alarm back-up battery replacement. What I like: 1. Initial high voltage level as received. My Fluke multi-meter measured the battery voltage in the range of 9.70-9.74 volts across all of the batteries. This is important because smoke alram manufacturers I have noticed are upping the minimum threshold voltage at which they trigger the infamous "chirp" in the middle of a cold night (when the resting voltage drops to its lowest). My newest Kiddie alarms start chirping at a full 9.2~9.21 volts - when the batteries are still considered charged and are useful. 2. Standard size, including length. Some replacement batteries are a bit longer and may not fit your device's battery compartment. I have no negative comments, though only when the middle of fall 2025 approaches will I know if these batteries have lasted.

Priced genuine lithium batteries at the store lately? They arn't giving them away are they. So what usually happens is you let your fingers do the walking through the internet yellow pages and eventually you end up on Amazon, you find exactly what you need and at an affordable price point so you don't have to take out a second mortage or sell the car to to buy genuine lithium batteries. The lights are on, but you're not home Your mind is not your own Your heart sweats, your body shakes Another Lithium battery is what it takes Whoa, you like to think that you're immune to the stuff, oh yeah It's closer to the truth to say you can't get enough You know you're gonna have to face it, you're addicted to lithium. Might as well face it your addicted to Lithium...

I cannot yet comment on their durability, however what you should know is they may not fit into all your devices. These batteries are slightly larger than standard (a common problem with many lithium batteries). No problem with my smoke detectors, but my VOM and stud finder are a no go.

Hoping these do the trick. I have a rental that really rents only during the summer season. After various types of smoke detector batteries, I am giving these a go. I do not want chirping in the middle of the night. Chirping equates to lost revenue. So let's hope these will do the trick and last.

So what kind of loser writes battery reviews? This one! I purchased a 4-pack for LED lights I like to use. These were the most powerful lithium batteries I could find at 1200mAh. They arrived well packaged and each battery had a nice rubber cap to prevent short circuits. Love it. They are extremely well manufactured. Slightly larger than standard--yes--so beware. But they are damned near perfect. When I hooked them up to my 9v LED, they cast the brightest light I have seen from it. Perhaps it is charged a bit above 12v....I'm not an engineer, what do I know? I just know these seem very well made, well packaged, and and appear to be made by a company that takes pride in its work. So I purchased a second four-pack.

Stopped the beeping lmao

I have had really good luck with these.. smoke detectors by their very nature are up high and inaccessible so when I get out the ladder and replace batteries its something that I dont want to re-do. These get the job done and its one less thing on my list.

excellent
