ACDelco 12-Count 9 Volt Batteries, Maximum Power Super Alkaline Battery, 7-Year Shelf Life, Reclosable Packaging

I bought these batteries to use with my Bounty Hunter Tracker IV. It takes 2 9V bats. Other reviews said I could expect 20-25 hours of use. Using headphones with my detectors I got between 30-35 hours of use. Really good batteries. But I have since bought 9V rechargeable batteries and a charger to alleviate having to buy new ones.

Best 9-volt battery deal on Amazon. They perform as well as much more expensive batteries.

All batteries tested at 9.65v on delivery. Longevity yet to be determined.

I use them primarily for smoke detectors. I don't want them to chirp unnecessarily or stop working. These batteries work well. I test them every few months and replace them about every 3 years. So far no problems. I've also used them in garage door remotes and alarm clock backup. No issues there either.

What would you like to know about this 9-volt? it opens my garage opener, and it powers my smoke detectors. I do not have any old remote control cars that require them, as I am old now. My wife almost forgot they made 9-volt batteries. In a day that everything gets charged into a USB for recharging, it is reassuring to stick a 9-volt into something and forget about its existence.

Great quality, long lasting

A good battery for the price. These work as well as any battery bought from any major store brand.

The package is marked "7 years guaranteed". The batteries are marked 08-30. Unless I forgot how to add, I think it is only 5 years + 3 months.Cannot comment on the longevity however I purchased AA batteries which worked well.
