Customer Reviews for Rayovac High Energy 9V Batteries (12-Pack), Alkaline 9 Volt Batteries

One of the batteries was already leaking. Their customer service was terrible.

Best for toys

As far as I can tell, all standard 9V alkaline batteries are equivalent in terms of shelf life and energy output. Rayovac is consistently cheaper, so why not get the most value for your money?

RAYOVAC IS MY GOTO FOR BATTERIES! They've never let me down and they are at a very reasonable cost. We keep a surplus for all my sons toys, remotes, and miscellaneous items. These in particular I use for my smoke & carbon monoxide detectors throughout the house. I can count on RAYOVAC for durability and safety!

Best price per at HD.

Excellent for smoke detectors. Last as long, if not longer than alkaline batteries and they're half the price.

They are batteries, what can I say...

The pack purchased contained 2 batteries, neither of which lasted any time when used as replacements in a home smoke detector. We were compelled in a matter of days to purchase additional batteries, and chose a different brand. No problem since.

both economical and reliable.

It works in my smoke detector

Batteries work well. I thought they were a little pricey.

For smoke detectors!
