Rayovac High Energy 9V Batteries (2 Pack), Alkaline 9 Volt Batteries

The rail, bike batteries I found over the years or very good batteries. I've used them many times and flashlights and a lot of my household electronics and they work and they lasted a very long time so I think they are one of the best products.

The ones that we had put in the smoke detectors years ago finally went dead so I figured I'd just replace them with the cheap brand that was in there since they had lasted for years. No need to spend the extra cash for a name brand. Assuming they last as long as the others is why I'll give it five stars for lower price and long life.

always good quality

These batteries are cheaper than the other brand names, but don't let that stop you from giving it a try. This is all I use. They last a very long time, sometimes longer than the brand names you find at your local stores. The best part is that the price is great.

These were actually pretty good batteries but didn't last very long Although for being inexpensive I decided on 4 stars I would rather pay a couple dollars more for a better lasting battery considering i use a tens unit daily for my back twitching Thats an ongoing issue so 9 volt batteries have to be at minimum 5 stars for my usage

My item arrive wrapped in a piece of paper. I am unsure of quality due to not knowing expiration date or other details that come on the original package.

These batteries are great and I do recommend them. However I'm a bit salty, and gave it a 1 star rating because I paid full price when ordering these online. When they arrived, the price tag said it was on sale for less than I paid for them. If you're gonna get these, buy them in store to save a bit of money.

I ordered 8 9Volt batteries in a plastic square box per the photo when ordered.  I received them all loose inside a floppy bubble wrap mailer. These could have started a fire if touched another one. These were not in the original package. There was no package, just loose inside the mailer/envelope.  How do I know these are even new?  These were even delayed shipment as well. The seller's reply to my email: "original box is huge and can not be fit into USPS priority mail and the USPS shipping cost will be $19.15 plus tax. Considering the major item is battery and we use the bubble to reduce shipping cost and sale price without damage the battery. If you need big battery box , we can send to you with extra $10 SH charge. The battery is protected with bubble and it is safe and no risk. You are welcome to return the item if not satisfication"

it doesn't work in the smoke detector

1 of the 2 batteries in the package was dead.
