Customer Ratings & Reviews

Great batteries. Energizers last longer than most other brands. Love the drum beating mascot!

Reliable product, been to using the brand for 40+ years

Needed them for my gate opener. Perfect fit and battery life

I used it for home fire sprinkler system. It worked.

I usually purchase this size of battery for our smoke and C02 detectors. Having spares is always important. The packaging makes it easy to store until needs.

Great battery life and so many come in one package.

Was hesitant after I read the reviews whether it would work for my smoke detectors .. it works like a charm

What can you say. Best 9 volt I have found to use.

Long lasting, fire detector needed a new battery..

Used this particular battery for our smoke alarms around the house. Very happy with this purchase. They last longer than most other brands in the market.

I needed a 9v that lasts. Bought this alkaline 9v.

I was looking for batteries and I found them. They were right there. In the store. All I had to do was buy them. I have a plastic card that had a predetermined spending limit and I was handed a dated paper confirming the transaction. It was wonderful.

Best 9V alkalines on the market. When you are involved in contracting or any kind of work that requires electrical diagnostics, those recharge nihm batteries don't cut it, your multimeter or other tool has to have a true 9 volts. Have went through 8 of these this year through heavy usage, no budget alkaline brand would last as long, and mid budget ones have spotty quality control. Can't speak for Duracell yet haven't tried their batteries besides some OEM ones in a flashlight I bought. Powerful, reliable, and worth it.

Worked as advertised. I'm using to test car speakers.

I finally figured out that it was less expensive to buy batteries from Best Buy than at the grocery. I keep a list of the batteries I need and on my next trip to Best Buy, I get my batteries there.... but why are 9V batteries so expensive compared to the other sizes?

Very handy when needing to install new smoke alarms, kids toys, etc.

COULDN'T FIND THE ELECTRONIC ONE FOR USE IN THE NEW FIRE DETECTORS BUT THEY ARE HOLDING MUCH LONGER THAN HDX.

These batteries tend to last longer than the value brands.

These batteries work fine. They are more expensive than other brands, but a better value when you buy them in multi-packs.

They're batteries. Pop them in the smoke detector and leave them there until it says battery low. and when it does, pop in the 2nd one.
