Unlike the alkaline batteries that had me up on a ladder every other month, these last six months or more between battery changes. What a pain to climb the ladder, remove the motion sensor from its mount, climb down the ladder, unscrew the battery cover and replace the battery. Once every six months is better than three times every six months. Less batteries used equals less money spent even if the lithium ion batteries are a bit more. The Amazon Basics brand helps take the bite out of the higher cost of lithium ion batteries. Happy with my purchase and will/have purchase(d) again.

I use these lithium 9volts for biometric gun safes. They last for years of opening and closing.

Little more power for wife’s tens unit

Price is very fair. Use it for diamond tester

I have never changed the battery in a smoke detector in such a short time. Incredibly disappointed in these,

I ran a capacity test on one of these, using a constant 60 milliamp load (0.060A). The result was an outstanding 1,148 milliamp hours! The battery didn't drop below 7v until the 1,025mAh mark (with the 60mA load). At lower loads, you could probably squeeze 1200mAh out of these.For comparison, an Amazon Basics Alkaline 9v gave me only 535mAh total and dropped below 7v at about 350mAh. Now, the Lithium batteries are about 3.5x the cost for 2x the capacity, so the Alkaline are a better "cost per mAh" if you don't mind changing batteries. But for low drain items, hard-to-reach items, or intermittent use items that sit in a drawer for long time -- I find the extra cost of the Lithium worthwhile.The combination of long shelf life, high capacity, better low-temp performance, and near leak-proof construction has me sold on these. Since Amazon doesn't specify the capacity in the product listing, they could change the specification at any time -- but I can say that the current product is a real winner!

I needed a lithium battery to replace the fire alarm battery in the shop after resetting it twice a day for a couple months because I just hate messing with fire alarm batteries. Some of them go into full blown fire alarm mode as soon as you remove the old battery, and it's completely ear and nerve shattering. This Amazon basic battery fit perfectly and no more beeping every 8 hours. A small victory in Gilda's life of just one thing after another :)

Amazon makes just about everything I can think of and fully supports there movement! From batteries to clothes and I’m also a shareholder!! Amazon if you see this, feel free to have me sample out anything new you start making and I will promise to leave an honest opinion on whatever it is. By the way. So far so good on the 9 volt battery! No limits to Amazon’s moves creating them a huge asset to consumers and any government contracts they have inline.

When I got these battles I checked the level power, both where completely charged and the batteries are working great.
