ACDelco 9V Batteries, Super Alkaline 9-Volt Battery, 12-Count

I bought 2 boxes of Delco 9V. I checked the batteries for leaks. They were fine. I took several and checked voltage with meter. They tested at 9.6V. I stored the batteries at room temperature. This should last me 5 years for the smoke detectors and the transmitters. I hope theyll be as good as today.

Good price for a great brand. I use AC Delco batteries exclusively after many years of trying other brands because of their long working life and reliability. No more ruined devices from sulphation.

I have used these before and they are as good as the more expensive brand.

Good value. Work well. Come in a snazzy plastic package, all lined up in a space-saving fashion. The color of the battery is nice too. Not sure what else there is to say.

Needed these for four Smoke and CO2 detectors. I knew I needed more than four so next year would be set with replacements. Pleased to see the expiration date of 2026!!!!! Thank you!

I really like the packaging. I can store these without scattering them all over the place. Costs a tiny but more but lasts longer in my Smoke/CO² detectors.

Great price! I figgured ACDelco should be a name you can trust... I put them in all the smoke detectors in our house. I don't know how long they will last, but i'm gonna find out...

Walmart does not have much quality in shipping their orders. The order (batteries) were shipped in an envelope and the plastic box of batteries were crushed, broken open, with batteries loose in the bag. The PROBLEM with this : Same thing happened a couple years ago with these 9Volt batteries. They were all loose, and some must have been in contact with each other and were VERY VERY HOT. So I am very concerned about the way batteries are packed and shipped.. Other that that they were fine. PS: these same batteries are $1.00 less expensive from AMAZON!

the batteries arrived on time and in gpod shape. I have used a 9 volt snd a few of AA and AAAs. The only reason for four stars is because I don't know how long the batteries will last. I'll follow-up later if I find short life batteries.

There were 4 items put in one big box with no packing to protect the items inside the box, so a package of batteries busted open and was all over bottom of big box.
