Been on these since the 80’s
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.

Great battery
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.

Trustworthy
I trust in my smoke detectors which says a lot about this brand . The output is consistent and lasts a long time without worry. A popular brand that is sold pretty much everywhere.

Expensive but worth it
The batteries themselves are fantastic, long lasting, and powerful. But the price is a little steep.
The packaging is minimal and made of cardboard, which is great for the planet and recycling.

Price
Long lasting especially if you go camping and you need for lights or a radio. Very common when you’re going to fish abroad with long lasting power
