I’m in my last few batteries but these lasted me a good four years. We use these for certain electronics and these last really long. One machine I use them for is a electric muscle massager which uses a lot of power and it’s 60 minutes per session. One battery lasts me weeks with continuous use so that means their capacity is really high and they drain slowly. They also offer a guarantee that if you’re not satisfied with the product you can call the number in the back and I assume they’ll give you replacements. Although these packs can be expensive, it’s one of those purchases you buy one time and you’re set for years.

From race car tracks teddy ruxpin to remote control cars and smoke detectors. I grew up in the 80’s where to see if these 9 volt batteries still worked you would lick them.

Best batteries I used no leakage output is great capacity awesome strong good last you for long time doesn’t get salty or rusty quality vs price totally worth it

One of the best and most reliable batteries out there. Not a huge need for 9V batteries much anymore but when I need one I go with Duracell every time.
